How we rate schools?

We rank middle schools across three criteria: Academics, Learning Environment, and Safety. We assess Academics primarily using statewide standardized test scores, by comparing each school’s test performance across subjects and years to the distribution of middle schools on the same tests in the state. We also assess a school’s Academics from the percent of students who passed Algebra I in 8th grade, which indicates a college academic track. 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, or 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.
