Occupational Group 330
In the California 2005 PD Rating Schedule, occupational group 330 covers jobs such as ARBOR PRESS OPERATOR, AUTOCLAVE OPERATOR, and BAND-SAWING MACHINE OPERATOR. 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 330 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 | F | 20% | ±0 |
| Shoulder | F | 20% | ±0 |
| Knee | F | 20% | ±0 |
| Wrist / carpal tunnel | F | 20% | ±0 |
| Grip / pinch strength | G | 22% | +2 |
| Psychiatric | F | 20% | ±0 |
| Hearing loss | E | 18% | -2 |
| Respiratory / lungs | F | 20% | ±0 |
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.

Group 330 rating FAQ
What is occupational group 330 in California workers’ comp?
Occupational group 330 is one of the 45 groups in the 2005 Permanent Disability Rating Schedule. It covers jobs such as ARBOR PRESS OPERATOR, AUTOCLAVE OPERATOR, and BAND-SAWING MACHINE OPERATOR. The group number sets the “occupational variant” applied to each impairment, which adjusts the standard rating up or down (PDRS Sections 4 and 5).
Does my occupational group change my permanent-disability rating?
Yes. After the whole-person impairment is converted to a standard rating, the occupational group applies a variant (C–J) that raises or lowers it before age adjustment. For group 330, a physical impairment such as a spine or knee injury barely changes the rating relative to the standard.
How much does group 330 adjust a 20% standard rating?
Spine: 20% (±0); Shoulder: 20% (±0); Knee: 20% (±0); Wrist / carpal tunnel: 20% (±0); Grip / pinch strength: 22% (+2); Psychiatric: 20% (±0); Hearing loss: 18% (-2); Respiratory / lungs: 20% (±0).
Is this a legal PD rating?
No — it’s an estimate for informational use. Always confirm the occupational variant and final rating against the DEU. RateString rates strict AMA Guides values under the 2005 PDRS.
