In 1983, a competency-based vocational education (CBVE) program began in Croydon Park College of TAFE, South Australia. This was six years before the Australian State Ministers of Vocational Education and Training decreed competency-based training (CBT) to be the national training imperative. Two reports were produced in 1985 and 1987, based on evaluations over a three-year period. 25 years on, the two authors have tracked down and interviewed some of the original staff in the program. This paper traces the vicissitudes of an idea – CBT – as it was conceived in 1982, implemented from 1983, evaluated over a three-year period and as it became transformed over the next generation. What were the features of CBVE then? How did these features alter over time? What contextual factors may account for shifts over this period? To respond to these questions, the paper uses data from 1983–85 and interview data from 2008.
