How the School Grade works

Results, not inputs. Math and reading proficiency on Connecticut’s state tests, each against the state average. Spending and class size are shown below but don’t count toward the grade. Tests: 2020–21; graduation: class of 2020.
The whole path. A town’s grade follows its kids: every district that serves it, weighted by the number of students tested in each.
Graded within the state. Each state writes its own tests, so districts are lined up against the rest of Connecticut only. A+ top 5%A next 10%A- next 10%B B+ to B−, next 30%C C+ to C−, next 30%D D and D−, bottom 15%
Individual schools are graded the same way on their own test results, against every public school in Connecticut with 25+ students. Private schools aren’t graded: they don’t take the state tests.
What a grade can’t tell you. Test results track family income closely, so a high grade partly reflects who lives in a town. That’s why we also compare towns with similar incomes. Visit, ask other parents, and read neighbor reviews. It’s our own summary of U.S. Department of Education data, not an official rating.
