The introduction explains the content and purpose of OCAPs.. Presented next are an OCAP listing competency builders in 8 technical skill areas specific to the electrical trades (safety, electrical principles, National Electrical Code, residential installations, commercial and industrial installations, commercial and industrial motor installations, specialized systems, and electronic applications) 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 the electrical trades, 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 79 academic competencies specific to the electrtcal trades. Concluding the OCAP is information on the OCAP verification panels.

According to the Action Plan for Accelerating the Modernization of Vocational Education: Ohio's Future at Work A comprehensive and verified employer competency list will be developed and kept current for each program Imperative 3, Objective 2 The Occupational Competency Analysis Profiles (OCAPs) are the Ohio Division of Vocational and Adult Education's response to that objective. OCAPs are competency listsverified by expert workersthat evolve from a modified DACUM job analysis process involving business, industry, labor, and community agency representatives from throughout Ohio. The OCAP process is directed by.the. Vocational Instructional Materials Laboratory located at The Ohio State University's Center on Education and Training for Employment. Each OCAP identifies the occupational, academic, and en.ployability skills (or competencies) needed to enter a given occupation or occupational area. The OCAP not only lists the competencies but also clusters those competencies into broader units and details the knowledge, skills, and attitudes (competency builders) needed to perform each competency. Within the competency list are two levels of items: core and advancing. Core items, which are essential for entry-level employment, are required to be taught and are the basis for questions on the Ohio Vocational Competency Assessment (OVCA). Advancing items (marked with an asterisk) are those needed to advance in a given occupation. Schbol districts may add as many units, competencies, and/or competency builders as desired to reflect local employment needs, trends, and specialties. Local advisory committees should be actively involved in the identification and verification of additional items. Vocational and applied academic instructors will be able to formulate their courses of study using the varied contents of the OCAP and will be able to monitor competency gains via the new criterion-referenced competency testing program, which is tied to the competencies identified on the OCAP. 4 1 Notes Occupational Competency.
