Applicants seeking a plumber's licence in Western Australia based on qualifications obtained outside WA must provide evidence that their trade skills have been assessed by a Registered Training Organisation (RTO) approved by the Plumbers Licensing Board to conduct a Technical Skills Assessment.

The Technical Skills Assessment consists of three stages:

1. Desktop review
2. Technical interview
3. Knowledge and practical assessment

The assessment is completed in two parts:

• Part 1: Desktop Review and Technical Interview – $820.00 - The applicant's qualifications and work history are reviewed to determine whether they are suitable to progress to the TSAR assessment.
• Part 2: TSAR Knowledge and Practical Assessment – $2,591.00 - The applicant completes the knowledge and practical assessment. Upon successful completion, they will be issued a Trades Skills Assessment Report (TSAR).

Following successful completion of the TSAR assessment, the applicant may apply for a provisional plumbing licence, allowing them to work under supervision while completing the additional training requirements for an unrestricted plumbing licence.

Additional requirements include:

• Logging the required hours of practical experience while working under supervision.
• Successfully completing the Migrant Plumbing Training Course (additional fees apply).

Once all training requirements have been completed, the applicant may apply for an unrestricted plumbing licence by providing a letter from the RTO confirming successful completion of the Migrant Plumbing Training Course.
