What this means: About 56% of students here test proficient in math and reading, compared with the roughly 43% typical for Maryland schools with a similar share of low-income students. BeatsExpectations measures results against demographically similar schools rather than by raw scores, and this school falls within the typical range, neither among Maryland's top nor bottom 10%.
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 MCAP?
Maryland public-school students take the Maryland Comprehensive Assessment Program (MCAP) in English Language Arts and Math each spring (grades 3-8 + grade 10). MCAP uses a 4-level performance scale, with Levels 3 and 4 indicating proficiency.
What does "% Proficient (Levels 3-4)" mean?
It is the percentage of students at the school who scored at Performance Level 3 ("Proficient") or Level 4 ("Distinguished") on MCAP. Levels 3 and 4 are MCAP's grade-level benchmark — top 2 of 4 performance levels. A higher number is better.
What does 57.9% mean for English Language Arts at Mattaponi Elementary?
It means about 57.9 percent of students tested at Mattaponi Elementary performed at grade level or above on the MCAP English Language Arts test in 2024-25. The statewide average for Maryland that year was 50.6%. 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 Maryland, 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?
Maryland State Department of Education, Maryland Comprehensive Assessment Program (MCAP). School-level Performance Level data scraped from the Maryland Report Card SPA. Headline metric is the cumulative 'Proficient or Distinguished' rate (Performance Levels 3 + 4 on MCAP's 4-level scale).
How often is it updated?
MCAP 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.
