How we rate schools?

We rank elementary schools across three criteria: Academics, Learning Environment, and Safety. We assess Academics using statewide standardized test scores, by comparing each school’s test performance to the distribution of elementary schools on the same test in the state. We then compute overall achievement by averaging a school’s standardized performance across subjects and years. 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 the Safety of an elementary school 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.
