This research was conducted to focus on the impact of students’ indiscipline on school management systems in Uganda and in particular Mbale district. The study that aimed at establishing the seriousness of the effects that indiscipline causes on school management systems was prompted by the public concern, especially through mass media, that indiscipline in educational institution has become rampant all over the world. To investigate the problem ten schools were sampled for the study; but to include day, boarding, single sex, mixed, private, government aided, ordinary and advanced level schools. The participants included: 10 head teachers sampled purposively randomly, 50 teachers and 40 members of Board of Governors/parents, Teachers Association randomly selected and 20 student leaders picked purposively randomly. A total of 120 persons participated in the study. The Headteachers were served with a key informants questionnaire guide which yielded quantitative data. Others were treated to the focus group discussion interview guide. Data was collected both quantitatively and qualitatively, coded, analyzed and triangulated. The Chi-square statistical analysis was used and it yielded significant results leading to the ejection of all the null hypotheses.
The researcher discussed the results relating the findings to those of the authorities quoted in the literature review. In the final analysis it was found that students’ indiscipline has a strong effect on the smooth running of school management systems in secondary schools in Uganda. The researcher recommended that school administrators need to get more exposure on the challenges exhibited by the increasing indiscipline of students so that they can come up with a common stand on how to deal with them.||en_US
