On the Alaska Science Assessment, Grade 10 Science is reported on a scale from 400 to 800 (2022 to 2025), and each score falls into one of 4 performance levels. Reaching Proficient, at 601 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 2022, Grade 10 Science has a new score scale (400 to 800) and new level names, so a score from before 2022 is not directly comparable to one from 2022 on. Percentiles are, because each year is compared with its own students.

Statewide in 2025, about 35% 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 Alaska public school students in grade 9 tested in ELA and math, and in grade 10 tested in science, by the school where they tested: PEAKS and the older science test in 2018 and 2019, AK STAR and the Alaska Science Assessment from 2022. Alaska hides a group's whole row when it is small; the statewide figures add up the district reports, since Alaska publishes no statewide breakdown by level.

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.
