iReady Diagnostic scores help parents and teachers understand how a student is performing in reading and mathematics. Instead of providing only a pass-or-fail result, iReady reports information such as a scale score, national percentile, placement level, and growth. These results can make it easier for families to identify strengths, understand learning gaps, and see how a student is progressing.

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 purpose: providing 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 rather than the introduction of an entirely unrelated assessment. Curriculum Associates says the assessment will continue to provide useful data, familiar reports, and instructional support.

During the transition, families may see several versions of the name:

iReady Diagnostic
iReady Inform
iReady Inform, formerly iReady Diagnostic

The assessment continues to measure reading and mathematics performance and helps schools determine what students know and where additional support may be needed.

Understanding iReady Math Scores

iReady Mathematics results provide information about a student's performance using a scale score and other measures. Parents should interpret the result using the child's grade, testing season, and the appropriate comparison information.

A Math score can help families understand areas of strength and identify skills that may benefit from additional instruction or practice.

Understanding iReady Reading Scores

iReady Reading results provide similar information about a student's developing reading skills.

Parents can review the scale score, national percentile, placement information, and growth to get a broader picture of Reading performance.

A child may have different results in Reading and Mathematics, so each subject should be considered separately.

Understanding iReady Growth

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

Parents can compare 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, while growth adds information about changes between assessment periods. Parents can discuss these results with teachers to better understand progress and future learning goals.

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.

Understanding scores and growth patterns often comes down to making numbers easier to interpret. The same principle applies when dealing with large figures in different numbering systems. Learning how to convert lakhs into crores can make financial data, population statistics, and educational budgets much easier to understand, especially when comparing large values. Just as a clear score guide breaks complex results into simple terms, knowing that 100 lakhs equals 1 crore helps readers quickly interpret numbers without unnecessary confusion.
