iready diagnostic scores readyscores.com by grade help parents and teachers understand how students are performing in reading and mathematics. Instead of showing only a pass-or-fail result, iReady provides a scale score, placement information, growth data, and national percentile comparisons. These results can help families identify strengths, understand learning gaps, and see which skills a child 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 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. Families may see both names during the transition: iReady Diagnostic iReady Inform iReady Inform, formerly iReady Diagnostic The important point is that the assessment continues to measure reading and mathematics performance and helps schools determine what students know and where additional support may be needed. How iReady Scores Work by Grade iReady results should always be interpreted according to the student's grade, subject, and testing season. A scale score from one grade should not automatically be compared with a score from another grade. Parents may see results for Grades K–8, with information covering: Kindergarten Grade 1 Grade 2 Grade 3 Grade 4 Grade 5 Grade 6 Grade 7 Grade 8 Each grade has its own expected performance ranges and comparison information. Understanding Math and Reading Scores iReady provides separate results for mathematics and reading. A student's performance can vary between the two subjects, so parents should review each result independently. Math results can provide information about developing mathematical skills, while reading results can help identify strengths and areas that may require additional practice. When reviewing either subject, parents should check the grade, testing season, scale score, percentile, placement information, and available growth data. Why Testing Season Matters iReady assessments may be taken during three main testing periods: Fall Winter Spring Student performance can change throughout the school year as children receive instruction and practice new skills. Because of this, a score should be compared with information from the correct testing season. For example, a Fall result should be compared with Fall information for the same grade and subject rather than directly with a Spring result. Understanding iReady Percentiles The national percentile helps parents understand how a student's performance compares with students in the relevant national comparison group. A percentile is not the percentage of questions answered correctly. Instead, it describes a student's relative performance compared with other students. A higher percentile generally means that the student performed better than a greater proportion of students in the comparison group. Parents should consider percentile information together with the scale score, placement, and growth rather than using the percentile as the only measure of performance. Understanding Placement and Growth Placement information can help teachers identify a student's current instructional needs. It can provide additional context about how performance relates to grade-level expectations. Growth information shows how performance changes over time. Reviewing multiple assessment results can help parents understand whether a child is making progress during the school year. Placement and growth should not be viewed as permanent labels. Students can develop skills through instruction, practice, and appropriate support. Find Updated iReady Score Charts Parents can view updated 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 and national comparisons can change throughout the school year. 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 way to understand an assessment result, parents can use the free iReady Score Calculator on ReadyScores.com. Enter the child's grade, subject, testing season, and scale score. The calculator can then explain the estimated national percentile, grade-level placement, how the result compares with relevant national information, and possible next steps. It can help answer common questions such as: Is this a good iReady score? Is my child near the national average? Is the score below or above grade level? What does the percentile mean? What should we work on next? Has my child made enough progress? The calculator works for reading, mathematics, or both subjects and covers the main Fall, Winter, and Spring testing windows.
