This study examined the management practices that affect the provision of guidance and counselling services in public secondary schools in Itezhi-Tezhi District, Zambia. The research was motivated by concerns regarding the ineffective implementation of guidance and counselling programs in schools despite their critical role in supporting learners' academic, social, and emotional development. The study employed a descriptive research design, utilizing both qualitative and quantitative approaches. Data were collected from head teachers, guidance teachers, and pupils through questionnaires and interviews. The findings revealed that several management-related factors significantly influence the effectiveness of guidance and counselling services. These include inadequate administrative support, lack of clear policy implementation, shortage of trained personnel, insufficient resources, poor time allocation, and negative attitudes towards guidance and counselling programs. Additionally, limited monitoring and evaluation mechanisms and weak coordination structures were found to hinder service delivery. The study concludes that effective management practices are essential for the successful implementation of guidance and counselling services in schools. It recommends that school administrators strengthen leadership support, ensure proper allocation of resources, promote staff training, and integrate guidance and counselling into the school timetable to enhance its effectiveness.
