School Environment: The sum of the standardized rank scores for average class size; student/faculty ratio; percentage of faculty with advanced degrees; and number of AP tests offered, which was calculated as a ratio of grade 11 and 12 enrollment in order not to penalize smaller schools. (Senior class size is shown in the published charts for reference only; it is not part of the ranking calculation.)
Student Performance: The sum of the standardized rank scores for average combined SAT score; percentage of students showing advanced proficiency on HSPA; and students scoring a 3 or higher on AP tests as a percentage of all juniors and seniors.
Student Outcomes: A single score based on a new graduation-rate calculation (four-year adjusted cohort graduation rate) introduced by New Jersey in 2011, as mandated by the federal government. Essentially, the adjusted cohort formula divides a school’s number of four-year graduates by the number of first-time ninth-graders who entered the cohort four years earlier.

Vocational schools: Schools defined in this category by the state Department of Education were ranked using the same methodology as other public schools, but with two exceptions. No average class size is available for these schools, since many students are shared with mainstream schools. Similarly, there is insufficient data on AP tests.
