LC 4660 requires the Administrative Director to amend the PD rating schedule once every ___ years.

• A. One year
• B. Three years
• C. Five years
• D. Ten years

Answer: (C)

The PD rating schedule is the set of impairment percentages used to translate medical impairment into a permanent disability rating. Under Labor Code 4660, the Administrative Director must update this schedule every five years. This cadence keeps the ratings aligned with current medical knowledge and practice, ensuring fairness as treatments and outcomes evolve. Updating more frequently (one year or three years) would create instability and administrative burden, while waiting ten years could make the schedule become outdated.
