This Occupational Competency Analysis Profile (OCAP) contains a competency list verified by expert workers and developed through a modified DACUM (Developing a Curriculum) involving business, industry, labor, and community agency representatives from Ohio. This OCAP identifies the occupational, academic, and employability skills (competencies) needed to enter building climate control occupations. The competencies are clustered into 12 units that cover the following topics: fundamental concepts of human comfort; fundamental concepts of the refrigeration cycle; fundamental concepts of electricity; basic safety procedures; basic shop practices and tools; preventive maintenance; installing refrigeration and air-conditioning equipment; troubleshooting refrigeration and air-conditioning equipment; servicing and repairing refrigeration and air-conditioning equipment; installing heating systems; troubleshooting heating systems; and servicing and repairing heating systems. In addition, employability competencies are grouped into 12 units: career development; decision making and problem solving; work ethic; job-seeking skills; job retention and career advancement skills; technology in the workplace; lifelong learning; economic education; balancing work and family; citizenship in the workplace; leadership; and entrepreneurship. The units detail the knowledge, skills, and attitudes (competency builders) needed to perform each competency. Within the competency list are two levels of items, core items essential for entry-level employment, and items needed to advance in heating, ventilation, air-conditioning, and refrigeration occupations. The OCAP guide also contains an academic job profile based on the Work Keys system that identifies the level of applied academic skills that students must master to qualify for and be successful in their occupations; a total list of academic competencies in communication, mathematics, and science that all students should master; and a specific list of academic competencies needed for heating, ventilation, air-conditioning, and refrigeration occupations .
