Gather evidence: Qualification or apprenticeship papers, employer templates and pay evidence for every job.
Apply and pay: MSA through the TRA Online Portal; OSAP through an approved RTO.
Assessment: MSA: documents only (about 120 days). OSAP: documents, then technical interview, then practical if licensed.
Outcome: Outcome letter emailed to you.
