Introduction The final two years of high school should do more than help students “finish requirements.” They should strengthen the habits that matter most after graduation: disciplined thinking, clear communication, intellectual honesty, and the confidence to learn independently.

The IB Diploma Programme (DP) at IST is built to develop those strengths. Students don’t just absorb content—they learn to make claims with evidence, weigh perspectives fairly, and communicate ideas with precision. They practice managing long-term deadlines, responding to feedback, and sustaining effort over time.

DP learning is intentionally both broad and deep. Students study across disciplines while also developing expertise in selected subjects through Higher Level coursework. At the same time, the DP Core—Creativity, Activity, Service (CAS), Theory of Knowledge (TOK), and the Extended Essay (EE)— develops research competence, reflection, ethical awareness, and real-world engagement.

This guide is designed to make the high school clear and manageable. It outlines diploma options at IST, what students will experience day to day, the headline milestones families should protect, and who to contact with questions. Read it as both a map for the journey ahead and an invitation to a kind of learning that changes students for the better.

Why IST DP? At IST, the final two years are the capstone of a fully aligned IB journey. Students enter DP fluent in inquiry, reflection, and international-mindedness—and we raise the ceiling. DP at IST balances rigorous academics with whole-student development: students learn to think deeply, communicate with precision, analyze complex information, and defend ideas with evidence. They also build the habits that matter most for college success—time management, resilience, and the ability to connect learning to real-world contexts.

Our promise is simple: whether a student pursues the full IB Diploma or earns course results through the same DP classes, the learning experience and expectations remain equally rigorous.

The difference is how students complete the final credentialing components—not the quality of the program or the outcomes it builds.

What kind of student thrives here?

Students thrive at IST DP when they’re curious, willing to wrestle with complexity, and open to feedback.

They don’t need to be “the smartest kid in the room.” They need to be the kind of learner who can ask good questions, revise their thinking, and show up consistently. If a student enjoys discussion, debate, labs, problemsolving, creative work, or building arguments from evidence, DP will feel like a home.

IST is also a strong fit for students who want a school culture that values kindness, perspective-taking, and global awareness alongside achievement. DP rewards students who can think beyond “right answers” and learn to make strong, ethical, wellsupported decisions—especially when the world is messy.

What outcomes do we build (no matter the credential path)?

Evidence-based thinking. Students learn to analyze information, evaluate claims, interpret data, and justify conclusions—skills that transfer to any university major or career.

Research and academic writing. Students learn to ask meaningful questions, locate and assess sources, and produce structured, credible writing.

Clear communication. Students develop confidence speaking and writing with precision —explaining ideas, defending arguments, and collaborating effectively.

Time management and resilience. Students learn to plan, prioritize, and sustain highquality work over time—one of the strongest predictors of college success.

Ethical, globally minded leadership. Students learn to weigh perspectives, consequences, and responsibility in an interconnected world.

IST is a strong fit for students who want a culture that values kindness, perspectivetaking, and global awareness alongside achievement. The DP rewards learners who can move beyond “right answers” to make thoughtful, ethical, evidence-based decisions— especially when real-world issues are complex.

In the pages that follow, you will see what each DP course looks like at IST—what students study, how learning runs week to week, and how IB results are earned in each subject.

To earn the IB Diploma, students study six DP subjects across languages, individuals and societies, sciences, mathematics, and the arts— selecting three at Higher Level and three at Standard Level. At IST, all students complete the same courses whether or not they ultimately pursue the full IB Diploma. The DP Core (CAS, TOK, and the Extended Essay) is completed in its full IB form by IB Diploma candidates.

All students also complete the DP Core: Theory of Knowledge (TOK) encourages students to question how knowledge is constructed and to explore connections between disciplines and perspectives while building philosophical inquiry skills.

The Extended Essay (EE) is an independent research project developing academic writing, inquiry, and self-management skills for university life. (IB Diploma candidates complete the full 4,000-word EE.) Creativity, Activity, Service (CAS) invites engagement in artistic pursuits, physical challenges, and community initiatives that promote balance, reflection, and purpose in and outside of school. (IB Diploma candidates complete CAS requirements and the full portfolio.)

IST combines academic rigor with balance and structure with freedom to develop individual pursuits, encouraging students to explore interdisciplinary connections, develop leadership through service, and build the self-management and inquiry skills essential for university success.

Graduates of the IB Diploma Programme are recognized worldwide for their preparation and achievement, with universities across the globe granting advanced standing, course credit, or direct admission to successful Diploma candidates.

Diploma Pathways

High School Faculty Spotlight Average of 18+ years of teaching experience. 100% hold bachelor’s degrees; 72% hold graduate-level degrees; 18% hold PhDs.

All IST students take the same courses.

Families typically finalize the decision to pursue the full IB Diploma at the end of DP1 (Grade 11).

IST Pathway (Course Results / IST Diploma): Students remain in the same DP courses, but may take SL courses only in DP2, may opt out of IB external assessments and complete IST campus-based final assessments instead, and may complete an EE-style research project at a reduced length if not pursuing the full IB Diploma.

Graduation Pathways

The IST Diploma

The IB Diploma

Upon successful completion of IST graduation requirements, students earn an IST High School Diploma (TEPSAC/TAPPS accredited). All 11th and 12th grade courses are college preparatory courses.

To earn the full IB Diploma, students complete six DP subjects (typically three at Higher Level and three at Standard Level) and successfully complete the DP Core: CAS, TOK, and the Extended Essay.

It’s important to distinguish between two types of results students earn during DP: Standard day to day course grades vs. the overall final IB score is determined from required Internal and External assessments. See individual course pages scoring sections for more details.

*Exams & Registrations (IBDP, SAT, ACT) not included in tuition fees.

The IB Diploma Programme at IST The IB Diploma Programme (DP Grades 11-12) is designed to develop strong subject knowledge while also building the habits universities expect: independent learning, clear communication, research competence, and ethical decision-making.

What makes the DP distinct Students do not just learn content—they learn how to build and defend ideas with evidence, consider multiple perspectives, and communicate with precision. Across two years, students practice long-term planning, revision based on feedback, and sustained performance under deadlines.

DP structure Students pursuing the full IB Diploma complete six subjects (typically three at Higher Level and three at Standard Level) plus the DP Core: Creativity, Activity, Service (CAS) Theory of Knowledge (TOK) Extended Essay (EE)

University recognition (important, but individualized) Universities worldwide recognize the strength of DP coursework. Admission and credit/placement policies vary by institution and programme. IST College Counseling will support students in researching recognition policies, building balanced plans, and aligning DP choices to postsecondary goals.

Planning note This guide provides a clear overview of expectations and key programme windows. Cohort-specific deadlines and exact dates are provided in the Two Year Assessment Calendar finalized in August of each student’s DP1 (Grade 11) year.

DP Courses at IST: A Shared Learning Journey The Diploma Programme is designed as a coherent two-year course of study, not a collection of disconnected classes. While each subject has its own content and assessment model, all DP courses at IST share a common purpose: to help students think deeply, communicate clearly, and apply learning in sophisticated, real-world ways. Across the programme, students build the habits that make advanced learning possible—strong reading and research skills, disciplined writing and problem-solving, effective time management, and the ability to reflect and improve through feedback.

You will notice a consistent rhythm across courses from DP1 to DP2. DP1 focuses on building the foundation: core concepts, key skills, and the academic routines students need to succeed. DP2 increases independence and performance: students refine their thinking, strengthen their ability to work under exam-style conditions where relevant, and complete major IB assessment components such as Internal Assessments and course-specific performance tasks. This gradual increase in sophistication is intentional; students are not expected to start at “IB or university level” on day one—they grow into it through structured practice.

At the heart of the DP is a shared emphasis on perspective, evidence, and responsible learning. Students learn to support claims with evidence, evaluate ideas fairly, and communicate with clarity and respect. They also learn to use academic integrity consistently and to manage long-term tasks with planning and resilience. Over two years, students develop more than subject knowledge—they develop the intellectual toolkit to succeed in university and beyond.

Each course page that follows explains what students study, how learning typically looks week to week, and how the final IB subject score (1–7) is calculated for that course.

Course lengths: All courses run the full two years (Class of 2028: August 2026 through May 2028graduation).

Standard level courses have a minimum of 150 hours of instruction, and High level courses have a minimum of 240 hours of instruction.

Choosing HL vs SL (simple guidance) Higher Level courses require deeper conceptual mastery and greater volume over two years. Students should choose HLs based on: sustained interest, demonstrated strength, and realistic workload balance alongside TOK, EE, CAS, and internal assessments.

Available courses each year/cohort dependent on student interests, staffing, and scheduling.

Group 1 Language A:

English Language & Literature Course overview DP English Language & Literature at IST is a two-year course in disciplined reading, clear thinking, and powerful communication. Students study literary and non-literary works to understand how meaning is shaped—by language, structure, voice, and context—and how writers and speakers build credibility, persuade audiences, and express complex ideas with precision. Across DP1, students strengthen close reading and analytical writing; across DP2, they develop greater independence and control, refining interpretation, synthesis, and argumentation under timed conditions. The through-line is simple and rigorous: strong claims are built through evidence, reasoning, and craft. By the end, students can write with authority, speak with confidence, and engage thoughtfully with challenging texts and ideas.

How students learn in this course (what it looks like week to week) Week to week, students move through a steady rhythm of close-reading workshops, guided discussion, and writing cycles built around feedback and revision. Lessons regularly shift from noticing details to forming interpretations, then shaping those interpretations into coherent arguments with purposeful structure and style.

Students practice comparative thinking deliberately—connecting works by technique, purpose, audience, and choices rather than surface topic. Oral work develops in stages from low-stakes practice to polished delivery, building clarity, poise, and control over ideas in real time.

Group 2 Language Acquisition: Spanish B

For students with existing proficiency in the target language

Course Overview DP Spanish B at IST is a two-year course designed to build real, usable communication—confident listening, reading, speaking, and writing in meaningful contexts. The curriculum is organized around five prescribed themes with which the students engage through written, audio, visual and audiovisual texts. Students learn Spanish through authentic language use: stories, articles, audio, conversations, and practical writing tasks with clear purposes and audiences. Across DP1, students build fluency and accuracy with strong scaffolds. Across DP2, they sharpen precision, tone, and complexity as they handle more demanding texts and sustained speaking. The through-line is purposeful communication: students learn to choose language that fits the situation. By the end, the course is designed to provide students with the necessary skills and intercultural understanding to enable them to communicate successfully in an environment where the Spanish is spoken. Students will develop into successful, effective communicators evidenced through receptive, productive and interactive skills.

How students learn in this course (what it looks like week to week) Week to week, students engage in predictable, confidence-building cycles: input (listening/reading), guided practice (vocabulary and structures in context), and output (speaking/writing for specific purposes). Classes include frequent short conversations, partner tasks, and structured discussions that grow into longer exchanges. Writing is taught as craft—planning, drafting, and refining for clarity and tone—while listening and reading build stamina through repeated exposure to authentic materials. Students regularly practice the kinds of tasks they will be asked to do in assessments, but always through real communication, not rote drills.

Group 2 Language Acquisition: Spanish ab initio

For students with no/low existing proficiency in the target language

Course Overview DP Spanish ab initio at IST is a two-year beginner language course designed for students with little to no prior experience in Spanish. There is a strong emphasis on encouraging students to develop intercultural understanding, open-mindedness, and the attitudes necessary for them to respect and evaluate a range of points of view. Students learn to communicate in practical, real-life situations—understanding spoken and written Spanish, expressing ideas clearly in speech and writing, and building confidence through steady, supported practice. Across DP1, students develop the essential foundations: high-frequency vocabulary, core grammar in context, accurate pronunciation, and the habits that make language learning stick. Across DP2, students move from supported production to more independent communication, expanding range, improving accuracy, and sustaining conversations with greater ease and flexibility. The course has a consistent throughline: communication with purpose—choosing language that fits the situation, the audience, and what you want to accomplish. Students regularly connect language to everyday life and cultural perspectives (media, routines, communities, and shared human experiences) while practicing respectful interpretation and appropriate expression. By the end of the course, students will have the necessary skills and intercultural understanding to enable them to communicate successfully in an environment where the language studied is spoken.

How students learn in this course (what it looks like week to week) Week to week, learning follows a predictable, confidence-building cycle: input (listening/reading), guided practice (vocabulary and structures in context), and output (speaking/writing for a clear purpose). Language ab initio students develop their receptive, productive and interactive skills while learning to communicate in the target language in familiar and unfamiliar contexts. Classes include frequent short speaking routines—partner talk, role-play, and structured discussion—so students build fluency through repetition without feeling put on the spot. Students work with authentic, level-appropriate audio and texts, then practice responding with increasing accuracy and independence. Writing is taught as a skill: students plan, draft, and revise short text types (such as emails, messages, blog-style posts, or short articles) with feedback that targets clarity organization, and language control.

How the final IB score (1–7) is calculated in this course: Your student’s IST course grade comes from ongoing coursework across the year. The final IB subject score (1– 7) comes from the IB assessment components below. Language ab initio is not offered as an HL course in the IB.

Group 3 Individuals & Societies: Psychology Course overview DP Psychology at IST is a two-year course that teaches students to think like researchers: to ask careful questions about human behavior, evaluate evidence, and draw well-supported conclusions.

Students explore how biological, cognitive, and sociocultural factors influence thinking and behavior, and they learn how psychologists design studies, interpret data, and weigh the strengths and limits of claims. Across DP1, students build foundational knowledge and learn how to write clear, structured responses using research appropriately; across DP2, they refine evaluation and synthesis, comparing studies and applying concepts to unfamiliar scenarios. The through-line is evidence over assumption —students learn how to think clearly about complex human questions without oversimplifying them.

How students learn in this course (what it looks like week to week) Week to week, students analyze studies, practice research-based writing, and build fluency with command terms through targeted practice. Lessons often begin with a question or scenario, then move into the evidence: what counts as good research, what conclusions are justified, and what limitations must be acknowledged. Students practice planning responses, integrating research accurately, and evaluating arguments with balance and clarity. Practical work emphasizes research skills and ethical study design, with frequent feedback cycles to improve precision and reasoning.

Group 4 Sciences: Chemistry Course overview DP Chemistry at IST is a two-year course that empowers students to explore and explain how matter behaves - both predictably and often paradoxically. Students investigate the 3D structure and properties of matter, bonding types, energetics, kinetics, and the mechanisms that drive chemical change. Across DP1, students develop strong foundations in the scientific method, using the chemical lexicon, quantitative reasoning, and lab techniques. Across DP2, they will integrate ideas across topics, interpret more complex data, and solve unfamiliar problems with expertise and confidence.

The through-line is model-based thinking: students learn to connect what they observe to what is happening at the molecular level, and to support explanations with evidence and calculation. By the end, students can analyze chemical systems, reason through multi-step problems, and communicate scientific conclusions clearly.

How students learn in this course (what it looks like week to week) Week to week, classes move between concept development, structured problem-solving, and handson practical work. Students learn to translate between representations (words, equations, graphs, the periodic table, molecular models), then apply those representations to real chemical questions. Labs are purposeful: students plan, observe, measure, analyze, evaluate error and uncertainty, and improve methods, they don't just “follow the procedure. Frequent practice with IB-style questions builds speed and accuracy, while teacher feedback focuses on precision, reasoning, and clear scientific communication.

Group 5 Math:

Applications and Interpretations (AI) Course overview DP Mathematics at IST is a two-year course that builds both mathematical fluency and mathematical judgment. Students strengthen core skills in algebra and functions, equations and inequalities, trigonometry, geometry, and sequences and series, while also developing confidence with probability, statistics, and data analysis. As the course progresses, students use these tools to model real situations, interpret graphs and results, and communicate solutions with clarity and precision.

Across DP1, the focus is on building strong foundations and flexible problem-solving habits; across DP2, students tackle more complex, multi-step problems and deepen their ability to reason, justify, and verify. Whether students are headed toward calculus-heavy university pathways or fields that rely on quantitative literacy, the through-line is the same: students learn to think mathematically— accurately, logically, and with purpose.

How students learn in this course (what it looks like week to week) Week to week, students practice through a blend of direct instruction, worked examples, independent problem sets, and collaborative problem-solving. Lessons emphasize reasoning steps and clarity of method, not just final answers. Students regularly interpret graphs and data, explain decisions, and revise solutions after feedback. Investigation work supports deeper understanding by asking students to explore patterns, test models, and communicate findings in a clear mathematical style.

Group 6 The Arts: Visual Arts Studio Course overview DP Visual Arts Studio at IST is a two-year course for students who want to think and work like artists —developing technique, building a personal voice, and learning to make intentional choices. Students explore materials and processes, study artists and art contexts, and practice turning ideas into strong visual outcomes through experimentation and reflection. Across DP1, students build foundational skills, creative habits, and artistic risk-taking; across DP2, they refine craftsmanship, deepen conceptual focus, and curate a coherent body of work that shows growth and intention. The throughline is purposeful creation: students learn to plan, test, revise, and communicate the “why” behind what they make.

How students learn in this course (what it looks like week to week) Week to week, students are actively making—sketching, experimenting, producing work, and documenting decisions. Studio time is structured around cycles: concept exploration critique revision refinement. Students regularly analyze artworks to learn strategies and vocabulary, then apply those insights to their own practice. Feedback is frequent and specific, helping students strengthen composition, technique, and conceptual clarity while maintaining individual style.

Students build strong documentation habits so their process and thinking are as visible and compelling as their final pieces.

Assessment in the IBDP In every DP course, assessment is ongoing and supports learning over time. Students receive frequent formative feedback and complete summative assessments that reflect IB expectations for skills, thinking, and communication.

Two important assessment layers: Course assessment at IST (for regular grades and transcripts).

Students complete regular tasks throughout the two years—writing, labs, 7 presentations, problem sets, performances, projects, and exams. Teachers assess learning using IB-aligned criteria, provide feedback, and report progress.

5 IB assessment (for official IB scores) IB subject results are determined by required IB assessment components that vary by 4 course, including: 3 the teacher and 1. Internal Assessments (IAs): major coursework tasks graded by externally moderated by the IB 2 2. External Assessments: IB examinations and/or externally graded components set 1 and marked by IB examiners

Academic integrity matters: Because internal assessments and core components contribute to official IB results, students must produce authentic work and document sources appropriately. IST teaches and reinforces academic integrity expectations and provides guidance about what support is allowed. Failure to uphold IB Academic Integrity requirements may disqualify students from the IB Diploma. Expectations are explicitly taught and reinforced across all DP courses.

Scoring snapshot Each DP subject is scored by the IB on a 1–7 scale (7 is highest). Students can earn up to 3 additional points from combined TOK/EE results, for a maximum diploma total of A B C D E or N 45 points. Weight of individual elements varies by course - see the breakdown on the individual course pages and the Grade Conversions section. .

Conditions for Awarding the IB Diploma The IB Diploma is awarded to students whose total score (including up to 3 points from TOK/EE) reaches or exceeds 24 points, and who also meet additional IB requirements.

In addition to earning sufficient points, diploma award depends on meeting IB requirements, including: Completion of CAS requirements and full portfolio Successful completion of TOK and EE components.

Satisfactory completion of all required assessment components (no missing components) Meeting minimum performance thresholds across subjects and levels (including Higher Level and Standard Level expectations) No academic misconduct penalty that affects the final award decision

IB Course Results Students who take DP courses may still receive official IB course results in individual subjects even if they do not earn the full IB Diploma—provided they are registered for IB assessments and complete the required assessment components for those subjects. Students who opt out of IB external assessments complete IST campus-based final assessments and earn IST course credit and transcript grades.

Grades vs Scores Understanding DP Scores Vs. Grades, Results, and the Diploma There are two types of results (scores and grades) - It is important to not confuse them: 1) IST course grades (for typical transcripts and report cards) Students complete regular coursework all year (assignments, labs/studio work, tests, essays, projects, presentations, etc.). These are assessed by teachers using IB-aligned expectations and appear on report cards and transcripts.

2) IB Diploma results (final IB scores) At the end of DP2, the IB awards official scores in each DP subject based on required IB assessments (which vary by course). These official IB scores are separate from IST course grades.

HOW IB SUBJECT SCORES WORK (1–7) Each IB subject is awarded a score from 1 to 7 (7 is highest).

A subject’s final IB score is based on a combination of: External assessments (IB exams and/or externally marked components), and Internal assessments (IAs) completed during the course (assessed by teachers using IB rubrics and moderated by the IB).

Important: the exact Weight differs by subject.

WHAT TOK + EE ADD (UP TO 3 POINTS) TOK and the Extended Essay are assessed6by the IB and can contribute up to 3 additional points to the overall diploma total (according to the IB’s TOK/EE matrix).

5 CAS is required for the diploma but does not earn points.

4 THE DIPLOMA TOTAL (OUT OF 45) The IB Diploma total is a maximum of 45 points: 3 Up to 42 points from six subjects (each out of 7) Plus up to 3 points from TOK + EE 2

“PASSING” THE IB DIPLOMA (WHAT IT 1REALLY MEANS) Earning the IB Diploma is not just about reaching a point total. In general, students must: Meet the IB’s minimum point requirement (commonly 24 points) Complete CAS requirements Submit all required assessment components (no missing pieces) Meet IB’s minimum expectations across HL/SL courses (specific conditions apply) Avoid academic misconduct penalties that can affect the final award decision (A full list of conditions is published by the IB A and is applied to each cohort.)

RESULTS TIMING (WHAT FAMILIES CAN EXPECT) B Most IB subject assessments are completed during DP2 (with internal assessments submitted during the year and examinations at the end of the programme).

C Official IB results are released after the examination session.

Students may request that results be sent to universities through the IB’s results service process.

Universities evaluate IB A scores using their own admission, placement, and credit policies and assign the point value based on those policies.

E The exact balance of internal vs. external assessment varies by subject. (See individual course syllabi for details and percentages.)

Key Date Windows Non-negotiable deadlines Major milestones happen in predictable windows across DP1 and DP2. Internal assessments and core deadlines build steadily through DP2, mock exams occur mid-year of DP2, and final IB examinations take place in May of DP2. Because these are sent to the IB to be scored or moderated by IB teachers worldwide, the deadlines and exam dates are fixed. No extensions or make-ups are possible for IB examinations. Final internal assessment submission deadlines are fixed once work is finalized for IB upload; late work risks missing IB submission requirements and the ability to earn the IB diploma.

College Counseling & University Planning Counselor: T.B.A. University planning begins early in DP1 and becomes increasingly individualized through DP2. Students build a balanced academic plan, develop a strong record of learning, and practice presenting themselves clearly through writing, reflection, activities, and evidence of growth.

Families can expect support in these areas: Course planning for best-fit pathways and HL/SL balance Understanding IB results and university recognition (credit/placement policies vary by institution) Building a healthy application timeline and decision-making process Guidance on written materials (essays and short responses) and application organization Planning for deadlines while protecting student wellbeing and sustainable routines 7 6

Testing note

2 1

Mr. Hyatt & college counselor to confirm and report ASAP

About IB credit/placement: Credit and advanced placement policies vary by university and sometimes by department. Students and families should rely on the university’s published recognition policy and confirm details for intended majors. IST counseling supports students in A documenting and planning for these policies—without assuming that any single policy B applies universally.

C

How families can help (realistically): Protect key programme windows (major IA deadlines, TOK/EE deadlines, mock exam D periods, and exam windows). Encourage steady habits over last-minute surges. When travel conflicts arise, communicate early—IB deadlines have limited to no flexibility.

E

Universities with Generous Credit* An IB Diploma means Time & Tuition Savings These schools often grant a semester or more of credit for strong IB scores: UT Austin, Texas A&M, University of Houston – State law: up to 24 credits UCLA, UC schools – HL 5–7 = up to 30 credits University of Michigan, University of Virginia – HL scores may earn 24–28 credits University of Colorado Boulder & Colorado State – Full IB Diploma = 24 credits Iowa State, BYU, BYU–Hawaii, Utah Valley University – Generous credit for HL 5–7.

Western Oregon University: IB Diploma with a score of 30+ grants guaranteed admission, sophomore standing, honors program entry, priority housing, and studyabroad opportunities.

College of Idaho: IB diploma (with a score of 28+) earns preferred admissions status, 30 credits, and merit scholarships up to $11,000/year. *ALL examples are provided for general awareness (based on information available 2025). Universities change recognition policies; families should confirm credit and placement directly through each university’s published policy.

Universities with Strong Recognition IB Diploma = Time & Tuition Savings These schools grant meaningful credit (often a semester), though with subject caps: USC – Up to 20 credits for a strong Diploma.

Boston University, NYU – Up to 32 credits for HL scores.

Pepperdine, University of San Diego, University of Illinois, University of Houston – HL 5–7 count toward major/minor requirements.

IB DP students often shorten their degree path while strengthening their admissions profile.

Universities with Placement Emphasis An IB Diploma means Recognition and Advanced Placement At these highly selective universities, IB carries enormous admissions weight. Credit is limited, but strong IB results often allow students to skip introductory courses and move directly into advanced study.

Brown University – HL scores may allow placement; credit is rare. Still, IB achievement is highly valued in admissions.

University of Chicago – Very limited credit, but IB Diploma strengthens admissions profile.

Duke University – Some HL 6–7 scores recognized for “International Placement Credit,” though not always toward graduation.

Stanford University – Limited credit; HL 7s sometimes earn placement into advanced courses.

Princeton University – No degree credit; departmental placement possible. IB is highly respected in admissions.

Massachusetts Institute of Technology (MIT) – HL 7s in Math or Physics may allow advanced placement, but not formal credit.

Harvard University – No credit, but strong IB performance allows placement out of certain introductory courses. IB is a major plus in admissions.

Columbia University – No official credit, but IB Diploma is considered one of the strongest possible academic programs for admissions.

Johns Hopkins University – Limited IB credit, but used widely for placement into advanced courses.

Auburn University – HL 5–7 may earn some course credit; policy varies by department.

Even without additional college credits, the IB diploma makes a student stand out in admissions. It signals readiness for elite academic environments.

University recognition and credit/placement for IB results vary by institution and programme—and policies change over time. What is consistent is what the DP builds: deep content mastery, strong academic writing, high-level problem solving, research competence, and the ability to perform under sustained deadlines.

IST College Counseling supports every family in researching current policies for the universities students are considering and planning course choices accordingly.

More Universities That Actively Favor DP Grads An IB Diploma often means access to exclusive scholarships and higher admissions rates Ivy League and Elite Institutions Admission rates for IB Diploma students at Ivy League schools can be as much as 18% higher compared to the general applicant pool.

The effect is even stronger—around 22% higher—for other top-tier universities outside the Ivy League.

Universities with scholarships specifically designated for IB DP graduates: Southern Methodist University (SMU) Florida State University (FSU) University of Oregon (UO) Oregon State University (OSU) College of Idaho University of Arizona (UA) University of Rochester Illinois State University Mississippi State University Drury University University of Calgary (Canada) University of Alberta (Canada) These examples show universities that actively recruit and offer structured advantages to IB students beyond credit alone.

Admissions officers value the IB DP because of its rigor—as one source puts it, “IB students tend to have higher GPAs and are admitted at notably higher rates.”

Insights IB DP graduates enroll and persist in college at stronger rates compared to the national average.

They’re more likely to graduate within 4 or 6 years—even more so if they completed the full diploma.

Nearly half attend highly selective colleges.

IB students demonstrate higher preparedness, managing college-level rigor and independent learning more effectively than peers.

Academic Preparedness & GPA A University of California study found IB students earned higher college GPAs and graduated at higher rates than peers.

Data from the University of Oregon Honors shows IB students strongly outperform in persistence and adaptation—especially in time management, workload resilience, and taking ownership of learning.
