Diagnostic Assessment

i-Ready Diagnostic is the heart of the i-Ready Assessment suite. This diagnostic assessment platform is designed with teachers in mind, to work on its own or with other i-Ready programs. The Grades K–12 diagnostic testing assessments manifests our core belief that all students can grow and achieve grade-level expectations. Use these diagnostic assessment tools to help educators see where students are, set high—but achievable—expectations for growth, and connect the right instructional tools to help them get there.


See Exactly Where Your Students Are

Our diagnostic evaluation prepares and equips teachers by delivering actionable data that addresses the first part of the learning process—knowing exactly where each student is. i-Ready Diagnostic provides teachers with a complete picture of student performance relating to their grade level and national norms. It also includes Lexile® and Quantile® information for insights into reading and mathematics performance. Select an option below to preview the reports for that subject.

While other assessments only report scores using national norms, i-Ready Diagnostic provides normative- and criterion-referenced data. This diagnostic test for students ultimately promotes equitable access and growth for every student—no matter their background. i-Ready Diagnostic also correlates to leading state and national assessments so that students become familiar with the rigor and format they will see on high-stakes tests.

i-Ready provides a lot of good resources for teachers to graph student growth. It’s a very visual way to show their data, and it’s easy for their families to understand. When the students can see where they’re starting and where they’ve grown, I think that it brings up their expectations because they see that they can do it, and they can see where they want to be.”
