How guidance and counselling services can shape students' behaviour in Zambia's public universities is not known. Thus the substantive aim of this study was to establish how guidance and counselling services can be used to shape students' behaviour. This paper is an excerpt from an on-going PhD thesis. A descriptive survey research design was used to collect, analyse and interpret both quantitative and qualitative data. A total of105 respondents who included Deans of Student's Affairs (DOSA), counsellors and students were selected for the study. In-depth interview guides, focus group discussions and self-administered questionnaires were used to collect data from the sample. The study established that guidance and counselling services can shape behaviour of students in Zambia's public universities. On the basis of the study findings, it is recommended that guidance and counselling be accessed by all students in public universities as it has the potential to shape and enhance positive behaviour among students.
