Bulletin #1 (24 July 2006)
Please note that in developing the ECRS suite from the Engineering Competence Standards (ECS) and the Higher Level Standards (HLS), some of these source Units have been combined. This means that in the published audit trail there may not be a reference to some of the ECS or HLS Units. For example, HLS Units 3.1.1 and 4.1.1 are now incorporated in the new ECRS Unit 5.01.
