On Texas's STAAR end-of-course (EOC) tests, Biology is reported on a scale from 1885 to 6615 (2026), and each score falls into one of 4 performance levels. Reaching Approaches, at 3550 or above, is the state's passing score.
The score ranges changed during these years, so each period has its own table below, newest first.
From 2026, Biology has a new score scale (1885 to 6615), so a score from before 2026 is not directly comparable to one from 2026 on. Percentiles are, because each year is compared with its own students.

Statewide in 2026, about 94% of the students counted for Biology reached Approaches or higher. The bar above shows the share at each level (left = lowest).
These counts are the students who took this STAAR end-of-course test in the spring (April or May) of that school year, first-time testers and retesters alike. December and June retests are not included. Middle-school students who take a course early, most often Algebra I, are counted at their middle school.

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 Biology score into an estimated percentile versus the school, district, county and the whole state, so you can see where a score stands, not just its level.
