MAP Testing Scores Explained for Parents
Making sense of RIT numbers, percentiles and your child's reading journey. Decode MAP Growth scores and learn how to support reading progress at home.
If your child has come home talking about MAP Growth, you may have felt a mix of curiosity and confusion. Those three-letter "RIT" numbers can look more like secret codes than a measure of reading progress. This guide unpacks the jargon in plain language and shows you how to use MAP scores to celebrate growth without piling on pressure.
MAP Reading Basics
What Is MAP Growth?
MAP (Measures of Academic Progress) Growth is an adaptive online assessment used in thousands of U.S. schools. During the Reading test, each answer determines the difficulty of the next question, zeroing in on a student's precise reading level. Because it adapts, MAP can track the same child from year to year and still stay challenging.
How the Reading Test Adapts
The engine behind MAP uses the Rasch Unit—or RIT—scale. Think of this scale like a yardstick with equal intervals. Whether a first grader or an eighth grader takes the test, a ten-point jump in RIT always signals the same amount of skill growth.
RIT Scores & Percentiles
The RIT Scale in Plain English
A RIT score isn't a percentage; it's more like a location marker on the reading road. Most second graders fall somewhere in the 170–195 range. Fourth graders tend to sit around 195–210. Because the scale is grade-independent, a high-achieving second grader and an on-track fourth grader could share a RIT.
Percentile vs. RIT: Why Both Matter
Percentiles compare your child to a national sample. A 65th-percentile score means your child out-performed sixty-five percent of peers. Percentiles help you see where a RIT falls in the broader landscape, while the RIT itself shows growth over time.
Grade-Level Benchmarks
Most districts use NWEA's national norms to establish grade-level expectations. Understanding these benchmarks helps you contextualize your child's performance without creating unnecessary pressure. Roughly speaking, fall RIT medians progress predictably: Grade 1 students typically score in the mid-160s, Grade 2 in the low-180s, Grade 3 in the low-190s, and Grade 4 in the high-190s to 200 range.
Remember: Your school's cut-points may differ slightly, but the pattern remains consistent—each grade typically shows eight to ten RIT points of growth between fall and spring assessments.
Because MAP's scale uses equal intervals, a ten-point gain represents the same amount of skill growth whether you're moving from 160 to 170 or 210 to 220. Students usually grow faster in early grades, then level out as skills become more sophisticated. If the winter test shows only a three-point increase, don't panic—that can still put a child on track for strong spring growth.
What Counts as a "Good" Score?
Every parent wonders where "good" starts, but the answer is more nuanced than a simple number. NWEA labels the 40th percentile as "low average," 41st-60th as "average," and 61st-80th as "high average." Anything above the 80th percentile indicates college-ready performance. However, these labels tell only part of the story.
Growth matters more than position: A child moving from the 20th to the 35th percentile in one year has made remarkable progress. Always compare each score to your child's previous performance, not just to classmates' results.
How to Help Your Child Improve
Reading growth hinges on consistent practice rather than intensive cram sessions before testing. Daily fifteen-minute reading sessions, followed by brief conversations about the story, build both fluency and comprehension more effectively than sporadic longer sessions. The key is variety—mix fiction and nonfiction, include graphic novels and poetry, and always let your child's interests guide book selection.
In the weeks before the next MAP window, focus on building reading stamina by gradually increasing the length of passages your child reads without breaks. This prepares them for the test format while strengthening their overall reading endurance. Remember that authentic reading experiences—discussing characters' motivations, predicting plot developments, making text-to-life connections—build the deep comprehension skills that MAP measures.
FAQs
Is a MAP score part of my child's grade?
Usually not. Teachers use MAP as one data point among many, but report-card grades typically reflect daily classwork, projects, and classroom assessments rather than standardized test scores.
What if my child is behind grade-level benchmarks?
Focus on daily reading habits rather than score anxiety. Read aloud together, encourage rereading of favorite books for fluency practice, and celebrate small improvements. Choose books slightly below your child's frustration level to build confidence rather than pushing age-rated titles that feel discouraging.
How do I find books that match my child's RIT?
Ask your school for a RIT-to-Lexile conversion chart, or use NWEA's free Reading Resources website to filter books by RIT range. Many library catalogs also allow you to search by reading level.
Can practice tests boost scores?
Familiarity with the test format can reduce anxiety, but the biggest score improvements come from regular reading and vocabulary-rich conversations rather than drill sheets or practice tests.
Bringing It Home
MAP scores aren't a verdict on your child's intelligence or potential—they're simply a roadmap for supporting continued growth. Celebrate each milestone, keep reading experiences joyful and pressure-free, and use the data to guide rather than dictate your next steps. When growth stalls or concerns arise, partner with your child's teacher early to develop targeted support strategies.
Remember: The goal isn't achieving perfect scores—it's nurturing a lifelong love of reading while building strong comprehension skills. Focus on progress, not perfection.
