What is Crime Grade?

Crime Grade uses a combination of official crime reports (FBI, state, and local law enforcement) and machine‐learning algorithms to fill in reporting gaps and correct errors, producing a single letter‐grade that reflects a neighborhood’s overall safety.

By integrating Crime Grade, parents see not only how well a school performs academically but also how safe the surrounding community is, giving a more complete picture of each school’s environment.
