On Iowa's ISASP, Grade 8 Science is reported on a scale from 385 to 720, and each score falls into one of 3 performance levels. Reaching Proficient (at 508 or above) is the state's grade-level, on-track benchmark.
| Level | Score range | What it means |
|---|---|---|
| Not Yet Proficient | 385–507 | The lowest level, well below grade-level expectations |

| Advanced | 609–720 | The highest level, above grade-level expectations |
Statewide in 2025, about 69% of Grade 8 students reached Proficient or Advanced in Science. The bar above shows the share at each level (left = lowest).
A score's meaning depends on where it lands in the ranges above, and on how it compares to other students. Our free tool turns a score into an estimated percentile versus the child's school, district and the whole state, so you can see exactly where a score stands, not just its level.
