This module, the second of four units about vocational competency measurement, is module 18 in the Vocational Education Curriculum Specialist series. The purpose stated for the document is to help vocational educators determine the specific job-related competencies that need to be tested. Content is organized into two sections, each of which focuses on one goal and two or more objectives. Section 1 describes the necessary steps for systematically determining requirements for vocational competency measures, including involvement of expert advisors, collection of job and task information for a specific occupation, and verification of task importance. Section 2 focuses on listing task priorities on the basis of which existing competency measures will be reviewed or new measures will be developed. Each section concludes with individual study activities, discussion questions, and group activities. Self-check items and possible responses to them are appended for use as a pretest and review of the module content. (YLB)
