Occupational Group 311
In the California 2005 PD Rating Schedule, occupational group 311 covers jobs such as CHIROPRACTOR, CHIROPRACTOR ASSISTANT, and MAKE-UP ARTIST, BODY. Your occupational group sets the variant applied to each impairment, which adjusts the standard rating up or down before the age adjustment. Here a physical impairment barely changes the rating.
How group 311 adjusts a rating
The occupational variant (C–J) for each impairment, and what it does to a standard 20% rating for this group.
| Impairment | Variant | Standard 20 → | Change |
|---|---|---|---|
| Spine — back / neck | G | 22% | +2 |
| Shoulder | F | 20% | ±0 |
| Knee | F | 20% | ±0 |
| Wrist / carpal tunnel | G | 22% | +2 |
| Grip / pinch strength | F | 20% | ±0 |
| Psychiatric | J | 29% | +9 |
| Hearing loss | J | 29% | +9 |
| Respiratory / lungs | G | 22% | +2 |
Illustrative: a standard rating of 20% is shown. The variant is fixed per impairment + group; the size of the adjustment scales with the rating (PDRS Section 5). The calculator applies the exact variant for your impairment.
