The share of the four-year graduating class who met CUNY's college-readiness standard in English — the level at which a student can start credit-bearing college courses without remedial classes. This covers English only, not mathematics, and is reported for high schools.

The share of students who attended more than 90% of their school days. The DOE publishes this as the positive counterpart to chronic absence, so a higher number is better.

The share of parents and guardians who responded positively to "At this school my child is safe" on the NYC School Survey. This reflects what families reported, not students or staff.

We don't rank schools on this one. Almost every family answers it positively, so NYC schools are bunched within a few points of each other and a ranking would turn that gap into a verdict it can't support. The range above is where the middle half of schools land.

The share of parents and guardians who responded positively to "School staff regularly communicate with me" on the NYC School Survey. This reflects what families reported, not students or staff.

The share of parents and guardians who responded positively to "I trust the principal/school leader at their word" on the NYC School Survey. It asks about the school leader specifically, not about teachers.

The DOE's estimate of how much economic hardship a school's students face. A student counts fully if their family receives public assistance, they lived in temporary housing in the past four years, or they are a recent-immigrant high schooler whose home language is not English. Otherwise they count by the poverty rate of their census tract. The school's figure is the average across its students, which is why it usually runs higher than the poverty measure.

The share of students the DOE counts as living in poverty. Because every NYC school serves free meals, the DOE identifies these students by matching against income-based assistance programs rather than by lunch-form applications.

The school's students-per-class ratio: total students in reported classes divided by the number of classes. It covers every class the school reports, so a school spanning elementary and middle grades includes both.
