These norms are based on Diagnostic data from the 2022–2023 school year and apply to the 2024–2025 school year. By finding a student’s scale score in the table, families and educators can see where that score falls among a nationally representative sample of students. A percentile indicates the percentage of students nationwide whose scores a given student’s performance meets or exceeds. For instance, a student at the 75th percentile scored as well or better than 75% of students in the same grade who took the i-Ready Diagnostic during the specified window.

Spring 2024-2025 – i-Ready Diagnostic Scores By Grade in Math (Percentiles).

Below is Table 1, which shows the Spring i-Ready Diagnostic for Mathematics percentile-to-score conversion ranges by grade level for Diagnostics taken between March 2 and the end of the school year. The analyses were based on the 2022–2023 academic year. Each percentile indicates how a student’s scaled score compares to a nationally representative sample of students in the same grade during this spring testing window.

This table displays the scaled score ranges associated with percentiles 1–99 for Grades K–8.

These Spring norms are based on Diagnostic data from the 2022–2023 academic year, and they apply to the 2024-2025 school year. By locating a student’s overall i-Ready Mathematics scale score in the table, educators and families can see where that score stands relative to a nationwide sample of students at the same grade level during the spring testing season. The percentile indicates the percentage of students at or below that performance level—for example, a score at the 30th percentile means the student performed as well or better than 30% of students in that grade who took the test in the spring.
