Scores and Placements
The i-Ready Diagnostic provides a complete picture of student performance with scores that relate to their grade-level and national norms. The scores that result from the Diagnostic describe student performance against grade-level criteria as well as against their peers. Information about Diagnostic scoring and placement is available below. For information about Diagnostic norms, please visit the Diagnostic norms page on this site.
Diagnostic Placements
Placement levels provide a criterion-referenced indication of a student’s performance based on grade level. It is determined based on specific scale score ranges for each chronological grade (i.e., the grade in which the student is currently enrolled). Students receive a placement that indicates if they are above grade level, on grade level, one grade level below, or two or more grade levels below.

Greater Insight into Student Performance
i-Ready’s 5-Level Placements were developed to provide better insight into student performance relative to grade-level proficiency. They mirror the same placements that are used to calculate student growth in the i-Ready growth model.
