This publication presents experimental estimates of completion and attrition rates for the latest commencing apprentice and trainee cohorts. Such up-to-date estimates are possible by applying a "life tables" methodology to simple cross tabulations of commencements, completions and cancellations/withdrawals. The resultant cross-sectional estimates reflect what completion and attrition rates would be if the patterns observed in a particular quarter remain unchanged for the life of the commencing cohort in that quarter. The estimates are derived from the Apprentice and Trainee Collection no. 63 (March 2010 estimates), which is compiled under the Australian Vocational Education and Training Management Information Statistical Standard (AVETMISS) for Apprentice and Trainee Collection Specifications, Release 6.0, March 2008.
