SJNCS 2014 ITBS STANDARDIZED TESTS SCORES & INFORMATION UNDERSTANDING THE TESTS


About the ITBS • Developed by the College of Education University of Iowa in 1935 • Is used nationwide by public as well as private and parochial schools • Name will now change to IOWA Assessments


New Version of the ITBS – Form E • It is still a norm-referenced test

• The new version was developed based on content from the Common Core State Standards. • The assessment focuses on reading, English, language arts, mathematics, science, and social studies. • Geared to assess student readiness for higher education and the world of work.


Appropriate Uses of ITBS Scores • Describe each student’s developmental level within a test area. • Identify student and group areas of relative strength and weakness in subject areas. • Monitor year-to-year growth

• Used for grouping students in the class • (Small Group Instruction) • As one criteria in the selection process for advanced classes and for the ESE program.


Norm-referenced Tests • Norm-referenced tests compare a student's achievement with students in a norm group. • After a test is created, it is administered to a large, diverse group of children which makes up the norm group. The children's scores are ranked from low to high performance. • The scores are then statistically manipulated to form a normal distribution. If a child scores at the 65th percentile, for example, it would mean that the child performed better than 65 percent of the children in the norm group. • This allows for a student's performance to be compared to a suitable control group and provide a fair assessment of their current cognitive functioning. From the NWEA


Percentile, NOT Percent • Suppose 100 people take a test of 50 items. • If one of them got 40 of the items correct, then the percentage that he got correct is 80. He got 80 percent of the items correct. • But we don't know what percentile he is in until we see what scores the other 99 people got. • Suppose that all 99 of those other people got only 60% (or fewer) of the items correct. Then the person who got 80% did better than all other 99 people. He did better than 99% of the whole group of 100, so he is in the 99th percentile. From: EnglishForums.com • ITBS SCORES ARE SHOWN AS PERCENTILES


National Percentile Rank (NPR) • Shows a student’s standing within the group of students in the same grade who were tested at the same time of the year. • Useful for determining areas of relative strength and weakness for an individual student, a class, or a grade group
