Independent Impairment Assessors

Independent Impairment Assessors (IIAs) are medical practitioners specially trained to conduct impairment assessments.  These assessments are required for a person injured in a transport accident, who has made a claim for impairment benefits as a result of sustaining a permanent impairment.

Impairment assessors play a critical role in ensuring the TAC provides timely and equitable lump sum benefits to a person injured in a transport accident.
