How iReady Scoring Works
The i-Ready Diagnostic assigns scores based on a scaled system, with typical scores for students ranging anywhere between 400 and 800 depending on the subject and grade. These scores are tied to grade-level benchmarks, allowing teachers and parents to see whether a student is performing below, on, or above grade level.
Scores are divided into performance categories:
- Mid or Above Grade Level
- Early On Grade Level
- One Grade Below
- Two or More Grades Below
These levels help educators tailor instruction to meet students' needs more effectively.

Average iReady Scores for 7th and 8th Grade
7th Grade iReady Score Range
In reading, the average iReady score for 7th graders typically falls between 580–610. In math, average scores usually range from 590–620. A “good” score would be one that places the student in the Mid or Above Grade Level category, which generally means scoring at or above 610 in reading and 620 in math.
8th Grade iReady Score Range
For 8th graders, the average reading score usually falls between 600–630, while math scores typically range from 610–640. A “good” score for 8th grade students would be anything in the 620+ range for reading and 640+ for math, indicating they are either on grade level or performing above expectations.
What Do These Scores Mean?
On Grade Level or Above
If a student is scoring on grade level or above, it’s a strong indicator they’re keeping up with academic expectations. These students are usually ready for new and more complex topics in reading comprehension and math problem-solving.
Below Grade Level
A student scoring one or more grade levels below may need additional help, whether through tutoring, one-on-one support, or targeted instruction. The goal of iReady is not to label students but to identify learning gaps and address them effectively.
Tips to Improve iReady Scores
Students looking to improve their iReady scores can benefit from a few focused strategies:
- Daily Reading Practice: Reading 20–30 minutes a day can boost vocabulary and comprehension skills.
- Consistent Math Practice: Using iReady’s online lessons or similar resources can reinforce concepts.
- Ask for Help: If a concept is unclear, students should reach out to their teacher or a tutor.
- Stay Positive: A growth mindset can help students tackle challenges with confidence.
Final Thoughts
A “good” iReady score for 7th and 8th graders is generally one that shows they are at or above grade level in reading and math. However, it’s important to remember that every student learns at their own pace. The iReady Diagnostic is just one part of a larger picture, helping guide teachers and families toward better support and instruction. Whether your child is above grade level or needs a little extra help, the focus should always be on progress and improvement.
