iReady scores help parents and teachers understand how a student is performing in reading and mathematics. Rather than providing only a pass-or-fail result, iReady reports information such as a scale score, national percentile, placement level, and growth. These results can help identify academic strengths, learning gaps, and the skills a student may need to work on next.



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 Scores in 2026



An iReady scale score provides a numerical measure of student performance. However, the score should always be considered alongside the student's grade, subject, and testing season.



The national percentile provides additional context by comparing a student's performance with the relevant national comparison group. Placement information can help explain instructional needs, while growth shows how performance changes over time.



Together, these results provide a more complete picture of student achievement.



iReady Reading and Math Scores



iReady provides assessment information for both Reading and Mathematics.



A student may perform differently in the two subjects. One subject may be a strength while another may require additional practice or instruction.



Parents should review each subject separately and consider the scale score, percentile, placement, and growth information rather than focusing on one number.



Understanding iReady Growth



Growth information helps parents understand how a student's performance changes across assessment periods.



Families can compare Fall, Winter, and Spring results to see whether their child is making progress throughout the school year.



A single score provides a snapshot of performance, while growth provides information about changes over time. Both can help parents and teachers discuss learning progress and future goals.



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.
