below demographic expectation
What this means: About 17% of students here test proficient in math and reading, below the roughly 36% typical for New Hampshire 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 →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 23.0% mean for English Language Arts at Henry J. McLaughlin Jr. Middle School?
It means about 23.0 percent of students tested at Henry J. McLaughlin Jr. Middle 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.
