Most of the remainder worked for manufacturing firms, government agencies, wholesale and retail establishments, and schools. Carpenters are employed throughout the country in almost every community. Some pick up skills informally by working under the supervision of experienced workers. Many acquire skills through vocational education. Others participate in employer training programs or apprenticeships.
Most employers recommend an apprenticeship as the best way to learn carpentry.
Because the number of apprenticeship programs is limited, however, only a small proportion of carpenters learn their trade through these programs. Apprenticeship programs are administered by local joint union-management committees of the United Brotherhood of Carpenters and Joiners of America, the Associated General Contractors, Inc., or the National Association of Home Builders. Apprenticeship applicants must generally be at least 17 years old and meet local requirements. For example, some union locals test an applicant's aptitude for carpentry. The length of the program, usually about 3 to 4 years, varies with the apprentice's skill.
