Frank Parsons is considered the father of vocational guidance. He wrote the first book on career choice in 1908. Vocational guidance aims to help individuals choose, prepare for, and progress in an occupation. It involves discovering one's interests and abilities, acquiring knowledge about different occupations, and developing decision-making skills to evaluate options. Various strategies are used, including career corners, conferences, industrial visits, and counseling. Factors like family, personality, economics, and public policy can influence vocational development. Vocational guidance counselors should provide impartial and confidential services to help people access educational and career information.
