Iowa Tests of Basic Skills (ITBS)
The Iowa Tests of Basic Skills are norm-referenced tests. Georgia law mandates that a nationally norm-referenced test, such as the ITBS, be administered annually to students in grades three, five, and eight. The purpose of a norm-referenced test is to obtain information about the performance of Georgia's students and compare it with that of students in a national sample. The results are used for evaluation, decision-making, and instructional improvement.
