About the Tests
- In 2010-2011 Iowa used the Iowa Test of Basic Skills (ITBS) to test students in grades 3 through 8 in reading and math.
- The results for grades 4 and 8 are displayed on GreatSchools profiles. The scores reflect the performance of students enrolled for the full academic year.
- The ITBS is a norm-referenced test, which means it measures how well students in Iowa score in comparison to their peers nationwide. Students who score at the 40th percentile are considered proficient.
- The goal is for all students to score at or above the proficient level.
