This workbook, intended for students who are in work-experience programs, or who have had work experience, contains career assessment activities which students can use to examine their preferences, aptitudes, and value system and compare them with current and past work experiences. The objective of this self-administered, self-instructional document is to help students better understand themselves and the world of work, and begin to see points of similarity and conflict between their self-perceived strengths and weaknesses and the demand of jobs and careers. The booklet contains three exercises, two of which can be repeated. The first exercise leads the student to examine his/her own preferences, aptitudes, or values--along particular dimensions independent of the student's current job placement or work history. Subsequent exercises encourage the student to rate current or past jobs along the same dimensions, compare the two ratings, and enter the comparisons on a summary sheet. The dimensions included in the 200 questions which make up the basic exercises are personal values, job characteristics, job requirements, personal strengths and weaknesses, tolerance for various physical and other occupational circumstances, and reactions to attitudes of others. Detailed explanations for use of this guide are included. (KC)
