Supersession

Lineage follows TGA's retrieved equivalence assertion (D-084): equivalent means the same entity under a new code, not equivalent means a separate entity with an edge between them. The equivalence below is TGA's, verbatim — not our inference.

Superseded by
  • CPC50412 supersedes CPC50408 — TGA equivalence: not equivalent (2013-02-06)
    “Revised qualification deemed not equivalent to CPC50408 A number of core units updated and deemed not equivalent to previous version Core and elective units revised resulting in a number of unit identifier changes”
    official relationship — Publisher-provided correspondence, hierarchy or succession — ABS ANZSCO↔OSCA correspondence, TGA supersession, TGA taxonomy occupations.

    limitations: Register supersession as published by TGA. Not a statement about equivalence of outcomes; see is_equivalent.

Which occupations does this qualification lead to?

3 occupations published by training.gov.au as an occupational outcome of these codes. This is what the register says, not evidence of labour-market outcome.
