The concordances presented in Appendixes A1, A2, B1 and B2 provide advice on the conceptual relationship between occupations in the two editions of ASCO. Appendixes A1 and A2 indicate the link from ASCO First Edition to the Second Edition. Appendixes B1 and B2 indicate the link from ASCO Second Edition to the First Edition. The letter 'p' indicates where there is a partial match from one edition to the other.

For example:

      p = partial match
      Medical Scientist
      Medical Laboratory Scientist
      Clinical Physical Scientist

The entry from Appendix B1 illustrated above indicates that the Second Edition occupation 2115-11 Medical Scientist comprises all jobs classified in the First Edition occupation 2109-11 Medical Laboratory Scientist and some of the jobs which were classified in the First Edition occupation 2109-13 Clinical Physical Scientist.

The concordances present important summary information for understanding the changes that have taken place in the definition of occupations between the First and Second Editions. They do not, however, identify the proportion of a First Edition class that would fall into a relevant Second Edition class and vice versa. This information is being compiled by coding 1996 Census of Population and Housing data to both the First and Second Editions.

The ABS will produce a link file indicating the one-to-one links and proportional relationships following completion of the processing of data from the 1996 Census of Population and Housing.

There are some cases where particular care should be exercised, if it is necessary to use the concordance to draw conclusions about the relationship between data sets coded to the different editions of the classification. These cases arise primarily from changes in coding practices for particular groups of occupations or from the emergence of new occupations in the Second Edition.

A discussion of these particular cases can be found at the end of Appendix B2. The relevant entries are referenced by notes in Appendixes B1 and B2.
