Industrial arts vocational teachers instruct students in their specialised field of study, industrial arts, which is predominantly practical in nature. They provide theoretical instruction in service of the practical skills and techniques the students must subsequently master for an industrial arts-related profession, working with wood and metal, such as carpenter or sheet metal worker. Industrial arts vocational teachers monitor the students' progress, assist individually when necessary, and evaluate their knowledge and performance on the subject of industrial arts through assignments, tests and examinations.
