The purpose of this study was to investigate the magnitude and location of wastage inrnsecondary schools of Kafa and Sheka Zones. It also attempted to identifY the majorrnfactors that contribute to pupils grade repetition and dropout. In addition, the studyrnwas concerned with determining the relationship between pupils', teachers and schoolrnvariables with rate of wastage. In order to attain the objective of the study descriptivernmethod was employed. The study was carried out on three senior secondary schoolsrnthat were selected using random sampling technique. The study also involved 206rnpupils, 42 teachers and three principals from the three sample schools. Datarnregarding pupils enrollment, repetition, drop outs and promotes were obtained fromrnthe documents of the sample schools. Questionnaires and documentary analysis werernthe instruments of data collection. The data gathered from documents andrnquestionnaires were analyzed using percentages and averages.rnBased on the results of the analysis, the highest percentage of repeaters wasrnamong females than among males for all grades 9-11. The highest percentage ofrnrepetition being observed at grades nine. It was also found out that the rate of droprnout was relatively higher for boys than for girls, in which the highest was observed atrngrade nine, Thus, the over all wastage rate was higher at grade nine. It was revealedrnthat pupils failure to study hard, shortage of time to study, economic problems, poorrnacademic performance and early marriage were among the major factors causingrnwastage rate of high magnitude. As a result, the wastage rate was found to be arnfunction of an interaction of multitudes of factors, which can be categorized intorneconomic, institutional, social and individual problems. Accordingly, thernimprovement of these variables may make a considerable change in the frequency ofrnwastage rate. Therefore, it is recommended that measures related to appropriate andrntimely provision of textbooks and learning materials, teachers training, raising thernparticipation of community, organizing local calendars, improving school services,rnand arranging tutorial classes to be taken to reduce the prevailing magnitude ofrnwastage
