A skills assessment is an evaluation by a designated assessing authority that compares your overseas qualifications and work experience against the Australian standard for a nominated occupation. A positive assessment is a prerequisite for many skilled migration visas.
Different authorities assess different fields. Engineers Australia assesses engineers, Trades Recognition Australia (TRA) assesses tradespeople, VETASSESS covers a wide range of professional and general occupations, and AHPRA-linked bodies handle registered health practitioners.
