District of Columbia Biology: what a high-school score means

On District of Columbia's DC Science Biology test, Biology is reported on a scale from 300 to 600 (2019, 2022, 2023 and 2025), and each score falls into one of 4 performance levels. Reaching Met Expectations, at 450 or above, is the state's proficiency line.

Who takes this test

These numbers are the DC public and public charter school students who took each high-school course exam (PARCC, then DC CAPE), by the school where they tested. Algebra I, Geometry and Algebra II count high-school students (grades 9-12) only; middle-school students who take those courses are not included. English I and II count every student who took them. Biology (the DC Science test) counts the high-school students who took it. OSSE hides groups of fewer than 10 students.

Is a particular score good?

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, LEA and the whole state, so you can see where a score stands, not just its level.
