How to read these scores
What is NYS Assessments + Regents?
New York public-school students in grades 3 through 8 take annual state assessments in English Language Arts and Math each spring, plus Science at grades 5 and 8. High school students take Regents Examinations in core subjects (ELA, Algebra I, Living Environment, etc.) which are required for a Regents diploma.
What does "% Proficient (Level 3 + Level 4)" mean?
It is the percentage of students at the school who scored at Level 3 ("Proficient") or Level 4 ("Excels at Standards") on the 3-8 test, or at the passing threshold (65 or above) on a Regents Examination. New York reports four performance levels for grades 3-8; Levels 3 and 4 indicate grade-level proficiency. A higher number is better.
What does 98.0% mean for English Language Arts at MILLBROOK HIGH SCHOOL?
It means about 98.0 percent of students tested at MILLBROOK HIGH SCHOOL performed at grade level or above on the NYS Assessments + Regents English Language Arts test in 2024-25. The statewide average for New York that year was 58.3%. 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 York, 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 York State Education Department (NYSED), Grades 3-8 ELA/Math/Science assessments + Regents Examinations, via the NYSED School Report Card database (data.nysed.gov). School-level All Students subgroup. Headline metric is the cumulative "Proficient" rate (Level 3 + Level 4 for 3-8; passing Regents score for HS).
How often is it updated?
NYS Assessments + Regents 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.
