What this means: About 84% of students here test proficient in math and reading, well above the roughly 61% typical for New Hampshire schools with a similar share of low-income students. BeatsExpectations ranks schools against others at the same poverty level, not by raw scores, so a school can post high scores and still fall short of its prediction, or post lower scores and still beat it. This school clears its prediction by about 22 points, placing it in New Hampshire's top 10%.
BeatsExpectations runs a per-state regression of proficiency on free/reduced-lunch share, then scores each school by residual.
How this is calculated →What is NHSAS?
NHSAS is the statewide standardized test administered by New Hampshire public schools.
What does "% Above Proficient (lvl 3+4)" 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 81.0% mean for English Language Arts at Riddle Brook School?
It means about 81.0 percent of students tested at Riddle Brook School performed at grade level or above on the NHSAS English Language Arts test in 2024-25. The statewide average for New Hampshire that year was 55.2%. 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 New Hampshire, 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?
New Hampshire Department of Education, New Hampshire Statewide Assessment System (NHSAS). School-level All Students subgroup from the NH DOE public disaggregated data CSV. Headline metric is the cumulative Level 3+4 rate ("Above Proficient").
How often is it updated?
NHSAS 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.
