High confidence. Built on 2,653 tested students and a graduating class of 5,760; ordinary year-to-year swings are unlikely to change the grade.
How the School Grade works
- Results, not inputs. Math and reading proficiency on California’s state tests, each against the state average, plus the four-year graduation rate. 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. Tests count 60% and graduation 40%.
- Graded within the state. Each state writes its own tests, so districts are lined up against the rest of California 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 California 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.
