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.

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.
The complete GAF → WPI chart
Every ratable score in the 2005 PDRS conversion (page 1-16). GAF 70 and above converts to 0% WPI — no ratable psychiatric impairment; the scale runs to GAF 1 = 90% WPI. Read straight from the engine’s table, so this chart cannot drift from the calculator above.

The WPI is only the first step — it still runs the ×1.4 adjustment, the occupational variant, and the age table before it becomes a percentage anyone pays on.
