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.

This lineage supersedes
  • CPC20712 supersedes CPC20711 — TGA equivalence: not equivalent (2013-02-06)
    “Revised qualification deemed not equivalent to CPC20711 Qualification packaging amended  same number of core and elective units required, but: • CPCPCM2050A moved from core to elective • CPCPDR3021A moved from elective to core Change to core units: • native CPC08 first aid unit (CPCPCM2011A) replaced with imported HLT07 unit (HLTFA211A) Core and elective units revised resulting in a number of unit identifier changes”
