This quantitative study analyzed the perceptions of students on teaching effectiveness in private higher education institutions in Botswana. An exploratory and descriptive survey research design was adopted in this study. A valid and reliable questionnaire was used to collect data through a survey of 560 stratified randomly sampled students in private higher education institutions in Botswana. A one sample t-test and an Independent t-test were used for data analysis. A significant high level of teaching effectiveness was determined. Several items measuring teaching effectiveness contributed significantly negative to teaching effectiveness and therefore, it was recommended that lecturers should use strategies to improve on those areas of teaching to enhance their teaching. No difference in teaching effectiveness was determined with respect to age, gender and nationality of the students. However, there was a significant difference in the students' perceptions on teaching effectiveness between the university and the non-university institutions and, lecturers were found to be more effective in their teaching at the universities as compared to the lecturers in the non-university institutions. Therefore, a further study exploring the factors contributing to such differences is recommended to improve the quality of teaching in the non-university type of private higher education institutions in Botswana.
