About the ITBS Tests and Iowa Assessments

The Iowa Assessments and ITBS tests can be given either as a Complete, Core, or Survey Battery. The Complete Battery is a collection of standardized tests used to measure a wide range of skills. The Core Battery uses the same tests as the Complete Battery, with the exclusion of the Science and Social Studies subtests. The Survey Battery includes the tests for Reading and Mathematics, in addition to either the Language or Written Expression tests.

The Iowa Assessments and the Core Curriculum

The old version of the ITBS tested students of all levels with a series of subtests that only partially belonged to Iowa's Core Curriculum. As of 2011, with the introduction of the Iowa Assessments Forms E/F, all of the subtests administered across all levels measure student standards within Iowa's Core Curriculum. The Core Curriculum was developed by the University of Iowa's Board of Educators to best prepare learners for college readiness and their futures in the workforce. With this goal in mind, the College of Education of the University of Iowa now distributes more extensive post-exam reports in an attempt to provide effective feedback for student progress.

ITBS Tests and Iowa Assessments Grades and Levels

The tests on the Iowa Assessments in 2017 are divided into Levels 5–18, which correspond roughly to the age and grade of the student. Each test level consists of a series of subtests, and each subtest measures several different skills. Each level of the Iowa Assessments may be administered in their entirety, or with only some of the subtests.

Age GradeTest Level
5 K.1-1.5 5
6 K.7-1.9 6
7 1.7-2.3 7
8 2.3-3.2 8

13 7 13
14 8 14
15 9 15
16 10 16
17 11 17
18 12 18

Decimals in the "Grade" column indicate the month of the school year. For example, K.1–1.5 means the first month of kindergarten through the fifth month of first grade.
