What is NJSLA?

What does 70.4% mean for English Language Arts at Peter Cooper School?

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 Jersey, 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 Jersey Department of Education, New Jersey Student Learning Assessments (NJSLA). Per-grade per-subject Spring administration: ELA grades 3-9, Math grades 3-8 + Algebra I/II + Geometry, Science grades 5/8/11. School-level All Students subgroup from the NJDOE Statewide Assessment Reports. Headline metric is the cumulative 'Meeting or Exceeding Expectations' rate (top 2 of 5 ELA/Math levels; top 2 of 4 Science levels).
How often is it updated?
NJSLA 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.
