In addition, the assistance of the following people was valuable to the production and redaction of this report: Danielle Baum, Kathryn McMullen, Richard Shillington, Karl Skof, Isabelle Thony, the members of the Canadian Council of Directors of Apprenticeship (CCDA) Research Committee and as well as the members of the CCDA Project Steering Committee. [...] The study also found an apparent relationship between the age of the apprentice at the start of the program and the likelihood of completion in two of the three jurisdictions (Ontario and Alberta) with the younger completing in higher proportion than the older; however, there was no apparent relationship between the nominal duration of a program and the completion rate. [...] The number of newly registered apprentices in the industrial and mechanical trades posted a 45% increase while the same number in the building and construction trades, in the food and services trades and in the metal fabricating trades posted a 16%, 16% and 21% decrease respectively. [...] The chart shows the attrition in the size of the continuer group over the years and the corresponding increases in the proportions of discontinuers and completers. [...] Then, in the following two years, the number of discontinuers grew faster than the number of completers so that, at the end of the third year, the number of discontinuers was twice the number of completers.
