Diagnostic Norms

i-Ready Diagnostic national norms provide a way for educators to understand student scores as they compare to the performance of students across the country. Norms are reported as percentile ranks that describe how a student’s score compares to the performance of nationally representative samples of student scores in the same grade level taking the Diagnostic at the same time of year.

Data on norms is reviewed regularly so updates to norms can be made when warranted. 

i-Ready will introduce new post-pandemic national norms in summer 2024. Based on a large, nationally representative data set, these norms will more accurately represent student performance after the interrupted learning experienced during the pandemic.

Using New Norms to Inform Instruction or Tiered Intervention  

New norms may have implications for districts that use percentile ranks to make instructional decisions about students, such as determining which students receive Tier 2 and Tier 3 intervention services or for determining eligibility requirements for certain coursework.
