MAP Growth scores explained for parents
What the RIT score means, how percentiles work, and how to read your child's MAP Growth report.
MAP Growth is an adaptive test schools use 2–3 times a year to track progress. Its scoring is different from a typical test — here's how to read it.
The RIT score
The RIT (Rasch Unit) is a stable scale that measures what your child knows regardless of grade. It's designed to grow over time — a 5th grader might score 210 in reading and aim higher by spring. RIT is not a percent-correct score.
The percentile
The report also shows a percentile vs. same-grade peers nationally. That tells you where your child stands; the RIT tells you how much they've grown.
What to focus on
Growth matters more than a single score. Look at the fall-to-spring RIT change and the suggested learning areas, then practice the skills just above your child's current level.
Common questions
What is a good MAP RIT score?
It depends on grade and season — compare to grade-level norms and, more importantly, to your child's own previous RIT to see growth.
