The One Major at a Time (OMAT) dropout program implemented for ninth and tenth graders by the Chicago, Illinois public schools is examined in this second year study. A description of the program includes information on its purpose, organization, instructional methods, student population, and objectives. Data on findings compare OMAT students with a control group of other high risk students in each of the program objective areas: (1) dropout rate, unexcused absences, and discipline referrals; and (2) grade-point averages in major subjects and reading achievement. Also included are summaries of student and teacher evaluations of OMAT. Recommendations for program improvement are given in the areas of inservice program needs, utilization of the reading laboratory, grading practices of OMAT, methods of measuring student attitudes, and selection of control groups. The report concludes that definite progress was made in several areas and cites higher reading achievement and student self-esteem, and lower dropout rates among OMAT students. Appended to this report are samples of the Self-Esteem Inventory test, survey of School Attitudes test, and My Views of the OMAT program test administered to students as well as a teacher perception questionnaire completed by faculty.
