This 60 item, paper-and-pencil test is designed to test knowledge and skill in the area of air conditioning.

Categories tested include: Print Reading, Electrical, and Test Equipment; Controls; Welding, Piping and Plumbing; Mechanical Maintenance & Machines and Equipment; Heating and Ventilation & Combustion; and Air Conditioning & Refrigeration.

The Air Conditioning Specialist Test was developed as part of the development of a series of skills tests. A shortened version consisting of 60 items, RCJS Air Conditioning Specialist – Form SWA-C, was developed in February of 2002. An on-line version Form SWA-E was developed in October of 2002. One item was altered slightly in the on-line version of the test in order to allow the use of a smaller schematic diagram.

The test was intended for use with applicants and incumbents for jobs where knowledge and skill in the area of air conditioning is a necessary part of job activities. Job analysis activities conducted during development of this test revealed that an applicable title is Heating and Air Conditioning Installer Servicer as defined in the Dictionary of Occupational Titles (U.S. Department of Labor, 1991) and Heating and Air Conditioning Mechanics and Installers, as defined on O*NET OnLine (National O*Net consortium for the U.S. Department of Labor, 2007).
