This report examines the costs that both employers and apprentices incur for undertaking training in the plumbing and electrical industries. The importance of understanding costs is fundamental. Employers will not take on apprentices if the cost is too high, and prospective apprentices will not undertake an apprenticeship if the future benefits (increased wages) do not outweigh the immediate costs to them. The research found that the apprenticeship model involves a substantial financial commitment from employers, and apprenticeships are more attractive to young people and will remain unattractive to older people, unless the premium paid to qualified tradespeople is substantial. Appendices include: (1) Details of case studies; and (2) Data collection sheets. (Contains 19 tables, 6 figures, and 5 footnotes.)
