Presented next are an OCAP listing competency builders in 13 technical skill areas specific to precision machining (safety/equipment maintenance; measuring workpieces; drawing interpretation/layout/inspection; benchwork; power saws; drilling, grinding, milling, and turning machines; numerical control and computer numerical control machinery; conventional electrical discharge machining machines; heat-treating equipment; and advanced machining technology) and an OCAP listing competency builders in 12 employability skill categories. A section on academic job profiles discusses the purpose of job profiling, presents an academic job profile for precision machining, and details the specific academic skills included in the following categories: applied mathematics, locating information, reading for information, applied technology, teamwork, listening, and writing. Included in a section on academic competencies are a master list of 504 academic competencies and a list of 62 academic competencies specific to precision machining. Concluding the OCAP is information on the OCAP verification panels. (MN)
