Undergraduate Highlights ABE’s undergraduate programs are consistently ranked amongst the top programs in the country according to U.S. News & World Report. The four degree programs are split, two and two, between two of the strongest and most respected colleges at ISU: The College of Engineering and the College of Agriculture and Life Sciences. We reached a milestone in undergraduate program enrollment this fall, with just over 600 students. And while we are part of a large campus community, the small size of our department allows for frequent student/faculty interaction and a truly familylike atmosphere – this is exemplified by recent exit survey data showing that students rated “departmental support of educational goals” as 4.7/5.0. And not only do student like their experiences – the job market recognizes the excellence of our students. Recent placement rates for the department have been above 95%, with students helping solve some problems in the agriculture, food, manufacturing, environment, and energy sectors. The department offers two popular technology degree programs: agricultural systems technology (AST) and industrial technology (ITec). These programs each enroll well over 150 students, with recent growth in both, but particularly in the ITec program thanks to focused recruiting efforts. The technology students are required to do internships prior to graduation, and rate these experiences among the most useful parts of their overall educational experience (4.7/5.0 on recent exit surveys). The technology programs are both accredited by Association of Technology, Management, and Applied Engineering (ATMAE) and departmental faculty and administrators are preparing for the upcoming 2014 accreditation visit. Technology students participate in a required two-semester, 6-credit capstone project experience, allowing students to dive into the details of an industrially-relevant project. For the past three years, ABE has been hosting a department-wide Capstone Day at the end of each semester, where students in the engineering and technology capstone courses present their work.

WWW.ABE.IASTATE.EDU/REPORTS

The department offers two undergraduate degree paths for engineers, agricultural engineering (A E) and biological systems engineering (BSE). Both curricula offer flexibility so that students can customize their studies to suit their career and research interests – there are three options in A E and four in BSE. With a recent decision by the Iowa Board to recognize the BSE program as effectively accredited, both A E and BSE students can take the fundamentals of engineering (FE) exam as a first step on their way to becoming licensed professional engineers. Both programs underwent an ABET accreditation visit in 2012 and results will be official in September 2013. In the past year, we utilized differential tuition funds to completely redesign our senior design capstone

teaming rooms. We also received College of Engineering Dean’s Education Initiative funds to enhance lab safety in the department (and across the college) and to develop hands-on experiences in freshmen engineering, sophomore heat/mass transfer, and electronics classes. Student participation in professional clubs is high – averaging three semesters of involvement for the last group of graduates surveyed. These clubs all are very active – for example, the ASABE and BSE clubs did five professional trips in the last academic year, and will do a similar number this year. They also invite industry speakers to their meetings, organize community service projects, and participate in the life of the department by assisting with key outreach efforts.
