A vocational school (or trade school or career school), providing vocational education, is a school in which students are taught the skills needed to perform a particular job. Traditionally, vocational schools have not existed to further education in the area of liberal arts, but rather to teach only job-specific skills, and as such have been better considered to be institutions devoted to training, and not liberal arts education. That purely vocational focus began changing in the 1990s "toward a broader preparation that develops the academic" and technical skills of students, as well as the vocational. Typically, most career colleges specifically design their curricula for fields that have the best current and future growth potential.
