The study focuses on seven plausible causes of turnover: salary and opportunities, administration and supervision, performance evaluation, teaching related factors, availability of better employment opportunities, students' character and environmental factors. The data analysis was made using percentage of frequency, median, weighted mean, standard deviation and ranking methods. Differences between different groups in terms of gender, length of service years, age, as well as between FOGSSTs and COGSSTs were also explored using Mann Whitney U Test. The results identified that turnover of teachers is a function of economic and managerial factors, whereas environmental factors and students' character are the least reasons for the problem. In relation to the groups, female, less experienced, younger and dissatisfied teachers tend to leave the schools at higher rate than their counterparts. Therefore, the prescriptions for the cure also lie in bringing about improvement in these factorsenOromia Government Secondary SchoolsThesis
