Know Thyself Manuals contain test protocols and summaries of test interpretations and were developed to be given to vocational rehabilitation clients in order to involve them in the assessment process. This example of a Know Thyself Manual demonstrates how the "know thyself" strategy is operationalized in an evaluation center using the following assessment procedures: the Employability Maturity Interview, the United States Employment Services Interest Inventory, the General Aptitude Test Battery or the Nonreading Aptitude Test Battery, the MicroTOWER, Occupational Report, job sampling, Sixteen Personality Factors Questionnaire with the Vocational Personality Report, Work Temperament Inventory, Personal Capacities Questionnaire, Job Seeking Skills Assessment, Work Personality Profile, and Work Performance Assessment. Part I of the manual is designed to explain the evaluation process to the client, identifying the instruments used and the reasons for using them. Part II is designed to share the results of the evaluation with the client, followed by the counselor and client together making decisions based upon the results. The "know thyself" approach, which focuses on choosing a job, getting a job, and keeping a job, has been found to be effective in enhancing vocational development. (Contains 21 references.) (JDD)
