A majority select their trade because it was something they had always wanted to do. Masters are often selected because they are relatives or family acquaintances. Costs of apprenticeship vary considerably among and within trades and from one country to another depending on demand and whether the master is a relative. Apprenticeship usually takes 3 or 4 years, and working hours are long. Usually, masters follow a training plan.
Apprentices learn technical skills as well as management and organization skills.
Intervention options should include measures aimed at apprentices or at masters.
