Most carpenters learn their trade through a 3- or 4-year apprenticeship. For each year of the program, apprentices must complete at least 144 hours of paid technical training and 2,000 hours of paid on-the-job training. In the technical training, apprentices learn carpentry basics, blueprint reading, mathematics, building code requirements, and safety and first-aid practices. Some 2-year technical schools offer carpentry degrees that are affiliated with unions and contractor organizations. Credits earned as part of an apprenticeship program usually count toward an associate’s degree.
