Scoring v2.1 — proxy academic scoring and private school thresholds
Schools without direct test data now receive proxy-based academic scores with tiered weight discounts, validated by holdout testing. Private school scoring thresholds raised.
Scoring v2.1 improves how we handle the ~33,000 schools that lack direct state test data — mostly private schools and specialized public programs.
- Tiered proxy academic scores: Schools without test data receive an estimated academic score based on directly-measured schools in their area. City-level proxies (from schools in the same city) carry 80% of normal academic weight. State-level proxies (statewide average) carry 65%. Every school page clearly indicates when a proxy score is used.
- Holdout validation: We validated these discount levels by holding out 10% of directly-measured schools, imputing their scores via proxy, and comparing to actuals. City proxies predicted within 1.5 points on average (10-point scale), state proxies within 1.7 points.
- Private school minimum components: Raised from 2 to 3. Private schools with only 2 thin components (representing ~45% of weight space) are now shown as “Not Yet Rated” instead of receiving misleading scores.
- Equity display change: Equity metrics (diversity index, demographics, FRL%) are now shown as informational context only — no longer displayed as a numeric score. Our poverty-adjusted academic score already accounts for socioeconomic context.
