Iowa Test of Basic Skills (ITBS)

What is the Iowa Basics Test (ITBS)?

The Iowa Tests are achievement tests published by the University of Iowa and are part of the “The Iowa Testing Programs.” The ITBS was the original Iowa Achievement Test. It was developed in 1935 and was originally called “Iowa Every Pupil Test of Basic Skills.” Over 80 years later, more-recent editions of the ITBS are still being used today as a tool to monitor and track student progress over time.

What does this graph show?

This graph represents our school’s composite scores by grade level of their National Grade equivalency. National Grade Equivalents (NGE) is a score that tracks students on a grade-level scale. The numerical value assigned to the NGE is a decimal value that illustrates academic performance in terms of grade level and month. Our 7th grade students, for example, averaged a score of 11.2 on the Math subtest. This shows they are scoring the average NGE for an 11th grader in his or her second month of the academic year.
