Impairment assessment

An impairment assessment is undertaken if a worker has a permanent impairment resulting from a work injury. When the work injury has stabilised, the worker's case manager will discuss referral to an accredited impairment assessor.

Impairment assessors are medical practitioners that are accredited under the Accreditation Scheme established by the Minister for Industrial Relations. Their role is to assess injured workers and prepare assessment reports in accordance with the Impairment assessment guidelines   (PDF, 1194 KB) to determine:

  • whether the injury has reached maximum medical improvement
  • whether the worker's injury has resulted in an impairment
  • whether the impairment is permanent
  • the degree of whole person impairment resulting from the work injury.

The degree of whole person impairment suffered by a worker will determine whether they are entitled to weekly payments after two years of incapacity and ongoing medical and like expenses and will be significant in determining their access to lump sum payments for economic and non-economic loss.

Further information about impairment assessments is detailed in section 22 of the Return to Work Act 2014.

An electronic copy of the Impairment assessment report template for physical and psychiatric assessment, which is mandatory to use, is available on our Impairment assessor news and resources page.
