This study aimed to investigate the role of guidance and counseling in promoting students' discipline within secondary schools in Ntungamo Municipality, Uganda. Maintaining discipline is important for learning outcomes but can be challenging, especially during adolescence. Guidance and counseling services provide support for students' personalsocial development and may help address issues leading to misconduct. A cross-sectional research design utilizing both quantitative and qualitative methods was employed. A sample of 40 students and 10 teachers from 4 randomly selected schools participated in the study between March and May 2023. Students completed a questionnaire to assess counseling exposure and perceptions of guidance influence on behavior. Teachers took part in in-depth interviews to offer perspectives on disciplinary trends and counseling impacts. The quantitative findings revealed a moderate positive correlation between frequency of counseling engagement and self-reported student discipline. Qualitative data generated richer insights into specific guidance strategies employed, such as individual sessions, mentorship programs and life skills training. Teachers observed declines in infractions like tardiness, disrespect and substance use coinciding with upgraded counseling provision over the last year. The study shown some of the issues that teachers refer to the teacher counsellor, majority refer cases of sexual relationship (40.2%), followed by social problems in home and at school (13.4%), laziness amongst students (13.4%), absenteeism (6.7%), cheating in examinations (6.7%), sneaking out of school (6.7%), truancy and students not keen in their academic work (6.7%) and when student decline to take the punishment given. School administrators should sensitize parents and introduce them to the idea of guidance and counselling since some of the disciplinary problems faced by students emanates from family factors.
