Independent Impairment Assessors

Independent Impairment Assessors

Independent Impairment Assessors (IIAs) are medical practitioners specially trained to conduct impairment assessments. These assessments are required of workers who have made a claim for impairment benefits as a result of sustaining a permanent impairment from a workplace injury, to assess their level of entitlement.

Impairment assessors, who represent over 25 medical specialities, deliver up to 8000 examinations each year, playing a critical role in ensuring that WorkSafe provides timely and equitable lump sum benefits to injured workers.


WorkSafe can pay the reasonable costs of your services as detailed in the relevant fee schedule.

Becoming an Independent Impairment Assessor

Training is provided by a training provider approved by the Minister for WorkSafe. The training course offers:

  • Administrative information on the assessment of impairment
  • Theory and practice of assessing impairment

For further information about the training course, contact AMA Victoria via email

Upon the successful completion of the impairment assessment training course, you can advise WorkSafe by emailing of your availability to accept referrals from a WorkSafe Agent.

Contacting WorkSafe

As an Independent Impairment Assessor accepting referrals from WorkSafe, it is important that WorkSafe's records contain your latest practice details (all consulting room contact and speciality practice information). If you have any changes, general questions regarding your role as an IIA or feedback, contact the Impairment Benefit Team.
