GAF score to WPI calculator
California rates psychiatric injuries from the evaluator’s Global Assessment of Functioning score. The 2005 PDRS converts GAF to whole person impairment on a fixed table (page 1-16): GAF 70 and above is no ratable impairment; lower functioning climbs toward 90% WPI. Enter the GAF from the report — the engine reads the exact table, then converts onward to PD.
For injuries on or after January 1, 2013, a psychiatric consequence of a physical injury generally cannot increase PD (violent-crime and catastrophic cases excepted) — though treatment remains covered. A direct psychiatric injury remains ratable. The math above is the schedule; whether it is compensable is the legal question — the psych guide walks the line.
The landmark conversions
Engine-read from the PDRS table, then rated at the age-neutral bracket for two occupations. Every cell recomputes from the tables on every build.
| GAF | WPI | PD · clerical (111) | PD · heavy (380) |
|---|---|---|---|
| 70 | 0% | — | — |
| 65 | 8% | 16% | 14% |
| 60 | 15% | 28% | 26% |
| 55 | 23% | 41% | 38% |
| 50 | 30% | 51% | 48% |
| 45 | 40% | 65% | 62% |
| 40 | 51% | 78% | 76% |
| 35 | 61% | 89% | 88% |
| 30 | 70% | 98% | 98% |
Note the inversion: unlike orthopedic injuries, psychiatric variants adjust clerical work up and heavy labor down. Price any PD result on the settlement calculator, or run the full case — apportionment, add-ons, CVC — in the free calculator.
