How we rate schools?

We rank high schools across three criteria: Academics, Learning Environment, and Safety. We assess Academics using statewide standardized test scores, by comparing each school’s test performance across subjects and years to the distribution of high schools on the same tests in the state. We also assess a school’s Academics using indicators of college readiness and likelihood of future college enrollment. These measures include the percent of students enrolled in at least one Advanced Placement or International Baccalaureate course and the percent of students taking the SAT or ACT. Next, we evaluate a school’s Learning Environment by combining various classroom indicators, such as the ratio of teachers to students and the percent of teachers who are novice, uncertified, and chronically absent. Finally, we measure Safety from the percent of students receiving in-school and out-of-school suspensions and the reported incidents of physical altercations per 100 students. While we recognize any ranking metric is inherently subjective, we believe our grades can serve as a valuable resource to help students and parents compare neighborhood schools and find the best school to fit their desired educational needs.
