Vocational jobs are careers that require specific skills or knowledge of a trade. These jobs do not require a four-year degree. Instead, you may learn the skills that you need through an apprenticeship, a vocational or trade school, or a technical program at a university or community college. This field typically refers to skilled, manual labor. Some of the most common vocational jobs include electricians, plumbers, HVAC installers, and auto mechanics. The duties and responsibilities of these positions vary, but in all of these careers, you learn through hands-on training with limited academic instruction.
