Program completion is positively related to a variety of demographic characteristics, including being married and having completed at least a high school education prior to beginning an apprenticeship. Males and females have similar completion probabilities. Completion is negatively related to time in the apprenticeship program (beyond the normal program length) and the number of employers during training. Type of technical training and having a journeyperson always present enhance the probability of completion. The regional unemployment rate has little effect on whether an individual completes an apprenticeship program or not. There are also large provincial and trade group differences.
