This study examines the usefulness of survey instruments in educational policy making in Liberia, a developing country. The chapter, "Liberia, an Overview," summarizes available background information about Liberian education and introduces the complex issues facing educational planners. "Procedures," discusses the general procedures followed in implementing the study, sample procedures, data collection and analysis, and the limitations of the study. "Demographic Teacher Characteristics," documents personal characteristics and parental backgrounds of Liberian teachers. "Teacher Educational and Experiental Backgrounds," examines the educational and experiential backgrounds of senior high school teachers. "Teacher Opinions and Perceptions" discusses teacher career choice, job satisfaction, career aspirations, general school climate, role behavior, teacher evaluation, and the changes desired in the schools. It is stated that the findings provide some insight into aspects of school practice and operation that should be examined closely as efforts are made to attract, select, and retain the caliber of teachers necessary to meet individual and national educational goals. Many tables illustrating the collected data are given. A copy of the questionnaire, list of schools in the final sample, list of occupations in Liberia, and tables of data on teacher time allocations are covered in the appendixes. (SK)
