A staffing ratio does not measure the quality of counseling, the number of appointments, the kinds of services offered, student outcomes, or whether another professional provides similar support. A counselor may serve multiple campuses, and local reporting practices can differ.
The data also cannot tell a family where to live or which school to choose. It describes a federal filing from one school year. Use it beside current information from the school or district, not in place of that information.
For the national table and comparison chart, see school counselor ratio data by state. For a step-by-step explanation, read how to calculate and interpret a counselor ratio. The CRDC glossary explains the federal source, and the methodology page documents K12 Atlas joins and missing-value rules.
