Vocational training refers to instructional programs or courses that focus on the skills required for a particular job function or trade. It is a type of education that prepares individuals for a skilled craft, trade, or work as a technician. Vocational education can also be seen as that type of education given to an individual to prepare that individual to be gainfully employed or self-employed with requisite skill. Vocational training can take place at the post-secondary, further education, or higher education level and can interact with the apprenticeship system. Vocational training programs are designed to provide students with the hands-on training required to work in specific careers. These programs can be taught at high school, in tech prep programs, and in post-secondary education. Vocational training can cover a wide scope of well-paying, satisfying jobs, including blue-collar professions, IT, healthcare, and the service industry. The cost of vocational training is generally cheaper than a university education, but the median salary of university graduates is generally higher.
