This booklet is designed to provide ideas on how youth competencies in the areas of basic education, pre-employment and work maturity, and job-specific skills can be utilized to help disabled youth meet performance standards in programs funded under the Job Training Partnership Act (JTPA). Discussed in the introductory section are the following topics: the basic provisions of the JTPA and their implications for disabled youth, adoption of a competency-based student evaluation system, the advantages and disadvantages of a competency-based system for student assessment, and strategies for helping a private industry council (PIC) develop a competency-based system. Next, three models of the competency development process are described. The next, three chapters, which constitute the bulk of the guide, contain numerous forms, questionnaires, and checklists that are currently being used by PICs and other JTPA-related agencies across the country to assess the competency levels of disabled clients with respect to the following skill areas: pre-employment and work maturity, basic education, and job-specific skills. Concluding the guide is a list of references and contact persons. (MN)
