This report summarizes the findings of three studies related to the effects of schooling on the employability development of youth. The first two studies described investigate determinants of attitudes and misbehavior in high school that are presumed to affect labor market outcomes later. The third study is presented as a complement to the first two studies and examines the effects of misbehavior in school, attitudinal variables developed while in school, and school characteristics on employment experience after leaving high school. An executive summary and introductory chapter are included. Chapter 2 assesses the effects of an active school guidance program on the development of positive self-esteem, on a sense of agency (internal locus of control), and on the congruence among career aspirations and abilities. Chapter 3 reports a study of factors that account for mild forms of deviance in high school (truancy, tardiness, cutting class, coming to class unprepared, and droppping out of school). The fourth chapter summarizes findings regarding the effects of attitudes, deviance in high school, school services, and staff attitudes on wages, hours at work, and employment after high school. Thirteen tables and eight figures are included throughout the text. (Author/NB)
