iReady Diagnostic Scores 2024-2025 – Reading: These are the i-Ready Percentiles and Diagnostic Scores chart by grade for Reading for students at Grade K to Grade 8. The Math scores table can be found at the iReady Math Scores page.
The i-Ready norms provide a way for teachers and educators to compare how students are performing, relative to all other students across the entire country.
The norms and scores in the tables and charts below will be introduced to the i-Ready system beginning Fall 2024.

What are i-Ready Diagnostic Scores or ‘Normative Scores’?
Norms are percentiles in i-Ready allow teachers and educators to compare their students’ performance with that of other students across the country. The iReady Diagnostic Scores refer to the testing scores.
How to Interpret i-Ready Diagnostic National Norms?
Norms are percentiles showing how a student performed compared to a nationally representative sample of students in the same grade who took the Diagnostic at the same time of year. For example, a fall Diagnostic norm of 90 means the student scored better than 90% of similar students.
Normative scores, along with criterion-referenced scores (e.g., grade-level placements for reading and math), give educators a complete picture of student performance. Normative scores show how students perform relative to others, while criterion-referenced scores show what students know and can do against grade-level standards.
Norms are available for both i-Ready Diagnostics for Reading and Mathematics.
Where to Find National Norms in i-Ready?
Normative scores, labeled as “percentile ranks,” are found in the Diagnostic Results (Class) report, the Diagnostic Results (Student) report, and the Diagnostic Results export on the i-Ready platform.

The previous norms were from the 2020-2021 to the 2023-2024 school years, based on 2018-2019 data. Before that, the update was in 2015-2016.
Next Update for i-Ready Diagnostic Norms.
Curriculum Associates reviews norms yearly and updates them as needed to ensure they reflect national student performance accurately.
