Ramsay Corporation's Electrical Aptitude Test was developed to be used to enable a quick 18-minute evaluation of a person's ability to learn electrical and maintenance job activities. This test is not designed to measure specific knowledge and skills, but rather the potential to be successful in an apprenticeship or trainee program for maintenance jobs.

Test items were written by two Industrial/Organizational psychologists based upon the six areas shown in Table 1 on the following page. These areas were selected from a review of recent books, tests, and training materials. The Ramsay Corporation Job Skills (RCJS) Electrical Aptitude Test Form REA was developed by Ramsay Corporation in April of 2002 to enable a quick evaluation of electrical aptitude. It was revised in September of 2003 to place test questions in a sectional spiral format, in which test items become more difficult as the test progresses. This format was suggested by job experts in early uses of the test. The revised test was RCJS Electrical Aptitude Test Form REA-R. The self-scoring format RCJS Electrical Aptitude Test Form EA-R-C was developed in May of 2004. At this time, seven items and four diagrams were revised slightly. RCJS Electrical Aptitude Test Form EA-R-C was updated in 2007. At that time, two items were replaced and one drawing was edited. RCJS Electrical Aptitude Test Form EA-R-C was revised and renamed RCJS Electrical Aptitude Test Form EA2-C in 2010. At that time, one item was replaced and five items were edited.
