A series of occupational competency tests representing all seven vocational education curriculum areas were developed, field tested, and validated. Seventeen occupations were selected for competency test development: agricultural chemicals applications technician, farm equipment mechanic, computer operator, word processing specialist, apparel sales, fabric sales, grocery clerk, hotel (motel) front office, dental assistant, physical therapist assistant, custom sewing, restaurant service (waiter, waitress, and cashier), electronics technician, water treatment technician, wastewater treatment technician, carpenter, and diesel mechanic. Identification of competencies involved development of a task inventory and task verification through interviews in the field. Test items were reviewed by experts representing vocational educators and employers, and the tests were revised and pilot tested. Over 3500 students in more than 150 sites in 37 states participated in the field testing. Contents of the final test packages were a job information (paper-and-pencil) test, a complete set of hands-on performance tests, a Work Habits Inventory (a teaching and counseling tool in job survival skills), and an Examiner's Manual. Test reliability and validity were also investigated, and a wide range of dissemination activities were undertaken to stimulate test usage and additional test development. Appendixes include a copy of the Work Habits Inventory. (YLB)
