Understanding Your Child’s i-Ready Diagnostic Scores for 2024-2025 – Reading
As a parent, you want to know how your child is progressing in their reading skills. The i-Ready Diagnostic Scores and Percentile Charts help you see where your child stands compared to other students nationwide. These scores apply to students from Kindergarten through 8th grade.
If you’re also looking for the Math scores, you can find them here: iReady Diagnostic Scores by Grade – Math.
The i-Ready norms give teachers valuable insights to track student progress and ensure they are on the right learning path. These benchmarks will officially update in the i-Ready system starting in Fall 2024.
When Are the i-Ready Diagnostic Tests Given?
The i-Ready Diagnostic assessment is administered at three key points throughout the school year. Each testing period, known as a ‘norming window,’ provides a snapshot of how students are developing their skills over time. The percentiles and scores may vary across these windows as students grow academically.
- Fall Testing Window: From the start of the school year until November 1.
- Winter Testing Window: November 16 to March 1.
- Spring Testing Window: March 2 to the end of the school year.
Understanding these scores can help you support your child’s learning journey. If you have any questions, consider reaching out to your child’s teacher for more insights on their progress.

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.
