The Iowa Tests®

Form C

The Iowa Tests Form C makes understanding and applying your student's test scores easy. It includes a Primary Reading Profile (PRP) score report for Kindergarten through Grade 3 and a Lexile® Measurement for Grades 1–12. An optional CCSS comparison (Grades 3–12) is available upon request and can be viewed in our sample score reports.

The Iowa Tests of Basic Skills® (ITBS®) and Iowa Tests of Educational Development® (ITED®) are also available in combination with the CogAT (Cognitive Abilities Test).
