This Policy Brief examines statewide student scoring on the Keystone exams given to 11th-graders. Several Allegheny County school districts’ results are also reviewed with emphasis on Pittsburgh Public School District (PPS).
The review begins with a look at the 2019 to 2025 comparison of achievement results since 2019 was the last year before COVID and its deleterious impact on educational achievement. At the state level, Keystone results for all three exams—math (Algebra 1), biology and literature (the stand-in for English) —all fell significantly from 2019 to 2025.
