Chicago Vocational Career Academy (commonly known as CVCA, Chicago Vocational High School or CVS) is a public 4-year vocational high school located in the Avalon Park neighborhood on the south side of Chicago, Illinois, United States. Operated by Chicago Public Schools, Chicago Vocational High School opened in 1940. The school was barely opened when the outbreak of World War II caused a change in plan. The school would be a vocational school, but one under the control of the United States Navy, where many mechanics who would build and repair aircraft, among others, were trained. After the war, the school was instrumental in helping returning veterans who went off to war prior to graduation to earn their diploma.
