This publication presents completion and attrition rates for apprentices and trainees using three different methodologies: (1) contract completion and attrition rates: based on the outcomes of contracts of training; (2) individual completion rates: based on contract completion rates and adjusted for factors representing average recommencements by occupation; and (3) projected contract completion and attrition rates for the latest commencing apprentice and trainee cohorts: based on a "life tables" methodology. Contract completion and attrition rates are derived by tracking the outcomes of contracts of training over time.
