On North Dakota's NDSA and ND A+ tests, Grade 10 Science is reported on a scale from 850 to 1150 (2025), and each score falls into one of 4 performance levels. Reaching Proficient, at 1021 or above, is the state's proficiency line.
The score ranges changed during these years, so each period has its own table below, newest first.
From 2025, Grade 10 Science has a new score scale (850 to 1150) and new level names, so a score from before 2025 is not directly comparable to one from 2025 on. Percentiles are, because each year is compared with its own students.
| Level | Score range | What it means | Statewide 2025 |
|---|---|---|---|
| Novice | 850–980 | The lowest level, well below the state standard | 36% |
| Approaching Proficient | 981–1020 | Approaching the state standard | 35% |
| Proficient | 1021–1074 | Meeting the state standard (the proficiency line) | 23% |
| Advanced | 1075–1150 | The highest level, above the state standard | 7% |
| Level | Score range | What it means |
|---|---|---|
| Novice | 900–972 | The lowest level, well below the state standard |
| Partially Proficient | 973–999 | Approaching the state standard |
| Proficient | 1000–1034 | Meeting the state standard (the proficiency line) |
| Advanced | 1035–1100 | The highest level, above the state standard |
Statewide in 2025, about 30% of the students counted for Grade 10 Science reached Proficient or Advanced. The bar above shows the share at each level (left = lowest).
These numbers are the North Dakota public school students in grade 10 tested on the state test, by the school where they tested. Through 2024 a district could give the ACT in grade 11 instead of the grade 10 ELA and math test, so those years count only the districts that gave the grade 10 test (about a third of the class); from 2025 every grade 10 student takes ND A+. Science counts nearly every grade 10 student. North Dakota prints each level as a percentage band for small groups, and the number tested is estimated from enrollment.

A score's meaning depends on where it lands in the ranges above, and on how it compares to other students who took the same test. Our free tool turns a Grade 10 Science score into an estimated percentile versus the school, district and the whole state, so you can see where a score stands, not just its level.
