i-Ready Placement Levels Explained
Read the placement labels in your child's school report alongside their national percentile. The two measures answer different questions.
Placement and Percentile Are Different Measures
A percentile describes national rank for the same grade, subject, and testing season. Placement describes performance against grade-level criteria. A high percentile does not automatically mean a student has met those criteria.
For example, the 50th percentile is the national median. It is not a cutoff for being on grade level. Use the school report to review overall placement and individual learning domains.
Mid or Above Grade Level
Meets or exceeds the report’s grade-level benchmark.
For parents: Discuss the domain results before selecting extension work.
Early On Grade Level
Partially meets grade-level expectations.
For parents: Ask which current-grade skills need continued instruction.
One Grade Level Below
Approaches current-grade expectations through skills from the preceding grade.
For parents: Discuss the testing season and specific skills when planning support.
Two Grade Levels Below
Indicates a need to strengthen skills below the enrolled grade.
For parents: Review the domain results with the teacher to plan targeted support.
Three or More Grade Levels Below
Indicates a need for substantial foundational support.
For parents: Work with the school on an individual support plan using multiple measures.

Where to Find Official i-Ready Placement Tables
Use the report supplied by your school for an individual placement decision. This guide explains the labels; our calculator provides percentile estimates.
- Open Curriculum Associates' official assessment resources and find the Diagnostic Scores and Placement Tables section.
- Choose the Grades K–12 Scale Score Placement Tables resource and check that its edition applies to the report you are reading.
- Select Math or Reading and the student's enrolled grade. Find the interval containing the scale score and read its placement label.
- Compare it with the school report's overall and domain results. If labels or editions differ, ask the school which table it uses.
Placement tables describe grade-level criteria. Fall, Winter, and Spring percentile tables compare students with peers and cannot substitute for placement tables.
Frequently Asked Questions
How is placement different from a percentile? ▾
A percentile compares a score with peers. Placement compares performance with grade-level criteria. One cannot be inferred from the other.
Is the 50th percentile the same as on grade level? ▾
No. The national median is not a grade-level proficiency cutoff. Read the placement in the school report.
Do five-level placement boundaries change each season? ▾
The official five-level placements use consistent criteria throughout the school year. Percentile comparisons use testing-season norms.
How do I find the correct placement for a score? ▾
Use the school report or the publisher’s placement tables for the student’s enrolled grade and subject. The calculator on this site estimates percentiles, not official placement.
Where can I find official i-Ready placement tables? ▾
Open Curriculum Associates' official assessment resources page and find Diagnostic Scores and Placement Tables, then Grades K–12 Scale Score Placement Tables. Use the applicable edition, subject, and enrolled grade to locate the scale-score interval. National percentile tables answer a different question; confirm individual results with the school report.
Can placement alone determine the support my child needs? ▾
Discuss overall and domain results, classroom work, and progress with the teacher before selecting instruction or support.
