What are the Iowa Test of Basic Skills (ITBS)?
The Iowa Test of Basic Skills (ITBS) is a group-administered achievement test for grades K-12 which measures a student’s knowledge in subject areas that students have learned in school – reading, language arts, mathematics, science and social studies. The Iowa Assessments were released in the 2011-2012 school year and has replaced the Iowa Test of Basic Skills® (ITBS) and Iowa Test of Educational Development®. The new exam format has been redesigned to better align the exam with the Iowa Common Core Standards. The test is also better aligned with other state standardized tests such as the Smarter Balanced Assessment exam.
