The Work Opportunity Center (WOC) is a vocational facility in a non-school setting with programs designed to meet the special needs of disadvantaged, inner city youth. This experimental program originally served 200 junior high youth who attended a half-day program of vocational and related training at the WOC. Emphasis throughout the program was placed on small classes, individualized instruction, and the development of positive work, school, and self attitudes. In order to evaluate the WOC, in comparison to the regular school program, an experimental study was designed. The experiment relied on home-school records and on pretest/posttest measures using the: (1) Vocational Development Inventory, Attitude Scale, (2) Self-Esteem Inventory, and (3) School Attitude Inventory. Based on the analysis of data, it was concluded that the WOC program was more effective in developing vocational maturity, increasing general self-esteem, increasing school self-esteem, and producing positive posttreatment school attitudes. A major recommendation is that career exploration learning laboratories with highly developed prevocational programs be made accessible to more students. (Author/JS)
