BeatsExpectations measures results against demographically similar schools rather than by raw scores, and this school falls within the typical range, neither among Alabama'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 ACAP?
ACAP is the statewide standardized test administered by Alabama public schools.
What does "% Proficient" 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 87.3% mean for English Language Arts at Mountain Brook Junior High School?
It means about 87.3 percent of students tested at Mountain Brook Junior High School performed at grade level or above on the ACAP English Language Arts test in 2024-25. The statewide average for Alabama that year was 52.7%. 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 Alabama, 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?
Alabama State Department of Education, Alabama Comprehensive Assessment Program (ACAP) Summative. School-level All Students subgroup from the Alabama Achieves Participation and Proficiency files. Headline metric is the cumulative 'Proficient' rate (Levels 3 + 4 on the 4-level ACAP scale).
How often is it updated?
ACAP 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.
