The DEU under the direction of AD will issue four types of ratings?

• A. Only as to the relationship between the disability described and the percentage of PD.
• B. To determine eligibility for benefits regardless of disability.
• C. Based on the duration of disability.
• D. According to the claimant's occupation.

Answer: (A)

The important idea here is how impairment ratings from the Disability Evaluation Unit are used to establish permanent disability. The DEU translates the medical description of a claimant’s disability into a corresponding percentage of permanent disability (PD) on the PD rating scale. In other words, the rating shows the relationship between what the disability is and how much PD it represents. This PD percentage is the basis for benefits calculations, but it doesn’t by itself decide eligibility, duration of disability, or factors like the claimant’s occupation. So the ratings are specifically about mapping the described disability to a PD percentage.
