- Check whether graduation confirms the pattern. When graduation and score point to different counties, inspect local districts more carefully.
- Treat spending as context. Spending helps explain resources, but it is not automatically a better-school label.
What it cannot decide
- It cannot confirm school attendance for a specific home address.
