iReady Diagnostic scale scores help parents and teachers understand how a student is performing in reading and mathematics. Unlike a simple percentage or pass-or-fail result, the scale score provides a consistent way to measure performance and track changes over time. Parents can use the score together with percentile, placement, and growth information to better understand a child’s learning progress.



For the 2026–2027 school year, parents may notice a new name on school reports. Curriculum Associates is changing iReady Diagnostic to iReady Inform for both reading and mathematics. The new name reflects the assessment’s main purpose: giving teachers, students, and families useful information that can guide instruction and learning decisions.



Is iReady Inform a Different Test?



The change from iReady Diagnostic to iReady Inform is primarily a rebrand, not the introduction of an entirely unrelated assessment. Curriculum Associates says the assessment will continue to provide valid and reliable data, familiar reports, and instructional support. A shorter assessment option will also be available during the 2026–2027 school year, responding to requests from educators to reduce testing time while preserving useful results.



This means families may see both names during the transition:



iReady Diagnostic

iReady Inform

iReady Inform, formerly iReady Diagnostic



The important point is that the assessment still measures reading and mathematics performance and helps schools determine what students know and where additional support may be needed.



Understanding iReady Scale Scores



An iReady scale score is a numerical result used to describe a student’s performance on the assessment. The score is more useful when it is considered with the student’s grade, subject, and testing season.



Parents should not assume that a higher or lower number automatically means a student is performing above or below grade level. The correct comparison information is needed to understand what the score represents.



Find Updated iReady Score Charts



Parents can view complete iReady score charts for the 2026 and 2027 school year at ReadyScores.com. The website includes reading and mathematics charts by grade, testing season, scale score, and national percentile.



The charts cover Fall, Winter, and Spring testing periods. This matters because average scores normally change during the school year. A score should therefore be compared with the correct grade, subject, and testing season.



ReadyScores.com presents iReady score charts based on published national norms, including percentile tables for Grades K–8. Parents can use the charts to see whether a score is below average, near the national average, or above average for a child’s grade and testing period.
