What this means: About 14% of students here test proficient in math and reading, below the roughly 35% typical for Pennsylvania schools with a similar share of low-income students. BeatsExpectations compares each school with others at the same poverty level, not by raw scores, so a school lands here when its results trail those comparable schools, which is not the same as having low scores. A higher-scoring school can still fall in this tier if similar schools score higher still.

BeatsExpectations runs a per-state regression of proficiency on free/reduced-lunch share, then scores each school by residual. How this is calculated →

How to read these scores

What is PSSA + Keystone?
PSSA + Keystone is the statewide standardized test administered by Pennsylvania public schools.
What does "% Proficient or Advanced" mean?
It is the share of students at the school who performed at grade level or above on the test, summed across the top two of four performance levels. A higher number is better.
What does 17.1% mean for English Language Arts / Literature at Lindley Academy CS at Birney?
It means about 17.1 percent of students tested at Lindley Academy CS at Birney performed at grade level or above on the PSSA + Keystone English Language Arts / Literature test in 2024-25. The statewide average for Pennsylvania that year was 51.1%. The other students fell into the lower performance levels.
How is the state average calculated?
It is a weighted average, not a simple average of each school's number. We multiply each public school's score by how many of its students tested, add those together for all schools in Pennsylvania, and divide by the total students tested that year. This way a big school with 1,500 students counts more than a small school with 50 students, which is the right way to ask "how did the typical student do this year?". District and county averages on this page use the same method, just scoped to that district or county.
Where does this data come from?
Pennsylvania Department of Education, Pennsylvania System of School Assessment (PSSA) for grades 3-8 and Keystone Exams (Literature, Algebra I, Biology) at the high-school level. School-level All Students subgroup, "Percent Proficient and above" column from the PDE school-level data downloads. Top 2 of 4 PA performance levels (Proficient + Advanced).
How often is it updated?
PSSA + Keystone is administered once a year (spring). Results are released by the state in the summer or early fall. We refresh this page after each annual release.
