When your child's MAP score comes back, the first question is whether the score is good for their grade. But the second — and often more telling — question is whether their score is growing fast enough. A student who starts Grade 3 at the 60th percentile and ends Grade 4 at the 55th percentile has grown in absolute RIT points but lost ground relative to peers. Understanding growth norms turns a score report from a one-time snapshot into a trajectory.
What Are MAP Growth Norms?
MAP Growth norms are published by NWEA and show the expected change in RIT score between two testing windows for students at various starting points. The most recent comprehensive norms are from the 2020 NWEA norming study, which remains the current reference for the 2025–26 school year.
Growth norms are separate from status norms (which show average scores at a point in time). A student who scores at the 70th percentile in fall and stays at the 70th percentile in spring has grown exactly as expected — their RIT score increased, but so did the cohort average. Staying at the same percentile over time means growing at the national average rate.
The key question growth norms answer: Is my child growing faster, at the same rate, or slower than the typical student who started at the same level?
MAP Math Growth Norms by Grade (Fall to Spring)
Math growth is relatively consistent and predictable — each year builds on the previous year's curriculum, so well-taught students grow steadily. Growth decelerates as students move through middle school, not because learning slows, but because the RIT scale is calibrated to reflect that maths becomes denser and more difficult with each year.
| Grade | Fall Average RIT | Spring Average RIT | Expected Gain |
|---|---|---|---|
| Kindergarten | 144 | ≈156 | ≈11.5 |
| Grade 1 | 163 | ≈173 | ≈9.9 |
| Grade 2 | 178 | ≈186 | ≈8.2 |
| Grade 3 | 188 | ≈195 | ≈7.4 |
| Grade 4 | 197 | ≈204 | ≈7.0 |
| Grade 5 | 205 | ≈211 | ≈6.4 |
| Grade 6 | 211 | ≈217 | ≈5.7 |
| Grade 7 | 215 | ≈220 | ≈4.5 |
| Grade 8 | 218 | ≈221 | ≈3.4 |

MAP Reading Growth Norms by Grade (Fall to Spring)
Reading growth follows a very different pattern from Math. Growth is rapid in Kindergarten through Grade 2 — the decoding and fluency phase — then decelerates sharply after Grade 3 as comprehension and vocabulary become the limiting factors. By Grade 7–8, a gain of even 2 RIT points over a full year is normal. This is not a sign of poor teaching or low effort; it reflects the nature of how reading comprehension develops.
| Grade | Fall Average RIT | Spring Average RIT | Expected Gain |
|---|---|---|---|
| Kindergarten | 155 | ≈166 | ≈11.0 |
| Grade 1 | 167 | ≈177 | ≈10.0 |
| Grade 2 | 182 | ≈190 | ≈8.4 |
| Grade 3 | 191 | ≈196 | ≈5.1 |
| Grade 4 | 203 | ≈207 | ≈4.2 |
| Grade 5 | 211 | ≈214 | ≈3.0 |
| Grade 6 | 214 | ≈216 | ≈2.2 |
| Grade 7 | 219 | ≈221 | ≈1.9 |
| Grade 8 | 221 | ≈222 | ≈1.3 |

How to Interpret Your Child's Growth
Compare your child's fall-to-spring RIT gain to the expected value for their grade in the tables above. A useful rule of thumb:
Growth is on track. No action needed beyond maintaining current habits.
Growth is below average. Worth discussing with the classroom teacher — ask whether MAP data showed specific skill gaps, and which subject area the shortfall was in.
Significant growth gap. Request a teacher conference, ask about the MAP Learning Continuum report, and consider whether subject-specific support is appropriate. One slow test window is not a crisis; two consecutive below-expected windows are worth acting on.
Strong growth. Maintain enrichment; consider whether the current level of challenge is sufficient. A student growing significantly faster than peers may benefit from acceleration or a gifted programme referral.
Why Does Reading Growth Slow After Grade 3?
The Reading deceleration after Grade 3 catches many parents off guard. A child who gained 8 RIT points in Grade 2 and gains only 3 in Grade 5 may seem to be regressing — but they are not. The explanation is structural.
In Grades K–2, the primary skill being measured is decoding — turning letters into sounds and sounds into words. This skill develops rapidly with instruction and produces large RIT gains. After Grade 2–3, most students can decode fluently. Reading progress from this point onward depends on vocabulary, background knowledge, and the ability to infer meaning from complex text. These skills grow slowly because they require broad experience rather than focused instruction.
The practical implication: from Grade 4 onward, reading at a level slightly above the child's current comfort zone — books and articles that require effort but are not frustrating — produces more Reading RIT growth than anything else.
