How to read a RIT score
A RIT score is a position on a continuous, equal-interval scale — not a percentage correct. The national average sits at the 50th percentile for each grade; the 75th–90th range is above average, and 95th–99th is where gifted screening typically begins. Because the scale is stable across grades, the most useful signal is often growth over time rather than a single number.

Frequently asked questions
What is a good NWEA MAP RIT score by grade?
A RIT at the 50th percentile is the national average for the grade (for example, about 188 in Grade 3 Fall Math, rising to about 218 by Grade 8). Scores at the 90th percentile and above are considered well above average, and the 95th–99th percentile range is where many gifted programmes screen.
What does a RIT score actually mean?
RIT (Rasch Unit) is a stable, equal-interval scale spanning the whole K–12 curriculum, so the same RIT score means the same level of knowledge regardless of grade. That lets you track growth year over year, not just rank within a grade.
Is my child gifted if they score in the 95th percentile?
A single MAP score is a screen, not a diagnosis. Many gifted programmes look for the 95th–99th percentile, but criteria vary by district and most combine MAP with a cognitive test (CogAT, NNAT) and teacher input.
How accurate are these numbers?
The benchmarks are approximate, based on NWEA national norms for Fall MAP Growth Mathematics. Exact percentiles vary by test term (Fall/Winter/Spring) and subject. For official figures, consult the NWEA 2020 Norms Study.
