Pennsylvania reports the Keystone Exams for its 11th graders. Each junior with a score is counted once, with their best Keystone score so far, whatever grade or test session it came from: a student can take an exam before 11th grade and can take it again. So a percentile here compares a score with juniors' best scores, and a school's numbers are its own 11th graders, wherever they tested. Fewer juniors are counted in 2021 to 2023, because the spring 2020 exams were cancelled, students who missed them did not have to test later, and fewer students tested in 2021. PDE says the 2021 results are not a representative sample.

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 Keystone Algebra I 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.
