The iReady Diagnostic assessment helps parents and teachers understand how a student is performing in reading and mathematics. Instead of providing only a pass-or-fail result, the assessment reports information such as a scale score, national percentile, placement level, and growth. These results can help identify academic strengths, learning gaps, and areas where additional support may be useful.



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.



How iReady Scores Are Reported



iReady results include several types of information that can help explain a student’s performance.



The scale score provides a numerical measure of performance. The national percentile provides context by comparing the student's performance with students in the relevant national comparison group.



Placement information can help teachers understand instructional needs, while growth information shows how performance changes across assessment periods.



Parents should consider these results together rather than focusing on one number.



How iReady Growth Is Reported



Growth information helps show how a student's performance changes over time.



Parents may review Fall, Winter, and Spring results to understand whether their child is making progress throughout the school year.



A single score provides a snapshot of performance. Growth provides additional information about changes between testing periods.



Parents can discuss growth results with teachers to understand whether progress is meeting expectations and which skills may need more attention.



Understanding Reading and Math Results



The iReady Diagnostic assessment provides information for both reading and mathematics.



A student may perform differently in the two subjects. For example, a child may demonstrate stronger reading performance while needing additional support in mathematics.



Parents should review each subject separately and consider the grade, testing season, scale score, percentile, placement, and growth.



Find Updated iReady Score Charts



Parents can view complete iReady score chart 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.



Use the Free iReady Score Calculator



For a faster answer, use the free iReady Score Calculator on ReadyScores.com.



Enter the child’s grade, subject, testing season, and scale score. The calculator then explains the estimated national percentile, grade-level placement, how the result compares with national averages, and possible next steps.



It can help answer common questions such as:



What does my child’s iReady score mean?

What percentile is my child in?

Is this a good iReady score?

Is the score below or above grade level?

Has my child made enough progress?

What should we work on next?



The calculator works for reading, mathematics, or both subjects and covers the main Fall, Winter, and Spring testing windows.
