Iowa Test of Basic Skills (ITBS Test)
What is the ITBS?
The ITBS® (Iowa Test of Basic Skills®) is a standardized achievement test that’s given to students from Kindergarten through 8th grade. And despite the name, it isn’t just given to children living in Iowa — rather, some states and many private schools administer the Iowa Test of Basic Skills® to assess each student’s grade-level performance and is written in levels 5-14. If your child is being tested for admission into a gifted and talented program, the ITBS is typically paired with another IQ measurement test, such as the WISC®-IV or the CogAT®.
Homeschooling families can also use the ITBS® to confirm a child’s learning progress, since the test is sufficient to meet state homeschool requirements. Iowa Test scores are also accepted by the National Honor Society to confirm a student’s eligibility.
Iowa Test levels 5-8 are administered to students from Kindergarten through 2nd grade, while levels 9-14 are given to students from 3rd to 8th grade. Each Iowa Test level consists of a series of subtests that are administered in sections by content.
