iReady Diagnostic growth scores help parents and teachers understand how a student’s performance changes over time in reading and mathematics. Instead of looking at one test result, growth information allows families to compare results from different testing periods and see whether a student is making progress. These results can help identify strengths, learning gaps, and areas that may need additional support.
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 Growth Scores
Growth information shows how a student’s performance changes between assessment periods. Parents may compare Fall, Winter, and Spring results to understand whether their child is making progress during the school year.
A single score provides information about performance at one point in time. Growth adds another perspective by showing how that performance changes over time.
Parents should consider growth together with the scale score, percentile, placement, grade, subject, and testing season.
How iReady Measures Student Progress
Student progress can be reviewed by comparing assessment results from different testing periods.
For example, parents may look at:
Fall results
Winter results
Spring results
A change between testing periods can provide useful information about learning progress. However, parents should avoid judging progress from the score difference alone. Teachers can provide additional context about classroom instruction and individual learning goals.
Find Updated iReady Score Charts
Parents can view complete iReady score chart 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.
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:
Has my child made enough progress?
Is this a good iReady score?
Is my child near the national average?
Is the score below or above grade level?
What should we work on next?
How does this result compare with previous scores?
The calculator works for reading, mathematics, or both subjects and covers the main Fall, Winter, and Spring testing windows.
