PS 121 Nelson a Rockefeller

PS 121 Nelson A. Rockefeller serves 299 students across kindergarten through eighth grade in Brooklyn, New York. With a composite score of 9.1 out of 10, the school earns an Exceptional rating — placing it 45th among 4,739 public schools statewide and 6th out of 570 public schools in Brooklyn.

In practical terms, it outperforms 99% of all New York schools. Academic performance drives a 9.0 score, while growth — measuring how much students advance relative to peers — reaches an even higher 9.4. That combination signals a school that doesn't just attract strong students but actively accelerates them.

The student-teacher ratio of 7.7 to 1 is notably low for a public elementary school, giving students more direct instructional time than most public school peers receive. For families weighing options in Brooklyn, PS 121 stands among a very small group at the top of a crowded field. Only 36 elementary schools in all of New York State rank higher.

The school's consistent strength across both academics and growth makes it one of the most complete performers at the elementary level in the state — a rare combination that separates it from the many schools that excel in one area but not the other.

With a student-teacher ratio of 7.7:1, PS 121 Nelson a Rockefeller offers a notably low ratio compared to the national average. This typically means smaller class sizes and more opportunities for one-on-one interaction between students and teachers.
