National BCA competency assessment system levels

Last updated: 15 March 2016

There are performance indicators and specifications for each core competency required.

The competency specifications have been developed to provide the assessor and candidate with a detailed set of knowledge and skills a person needs to be competent at a particular level.

We have provided a document for each competency level with details about the skills and knowledge required to be processed and inspected for it. They outline the mandatory criteria which must be achieved to demonstrate competency and gives guidance for assessors and candidates to consider. They also outline which sections of the Building Regulations 2006 are being assessed.

You can find the national competency levels and their subsequent documents below.
