The aim of this study was to investigate the effectiveness of School Intervention Teams (SITs) in assisting learners with Special Educational Needs (SEN) at community junior secondary schools (CJSS) in Botswana. This case study was guided by the cultural-historical theory on cognitive development by Lev Vygotsky and Bill Hettler’s theory on wellness dimensions. The study used mixed research approach which combined qualitative and quantitative method. The data collection instruments used included questionnaires which were completed by members of SITs, semi-structured oral interview which was specifically planned for SIT coordinators and lastly, document analysis. This research task was carried out under the permission of University of South Africa (UNISA) Ethics Clearance Committee and Ministry of Education and Skills Development (Botswana). Letters of consent were obtained from the school heads, SIT coordinators and members of SIT in the sampled community junior secondary schools (CJSS). The findings of this study showed that the effectiveness of SIT is dependent upon availability of positive attitude and support towards Inclusive Education by school management team, teachers, parents, external stakeholders (Botswana examinations Centre, Central Resource Centre, Principal Education Officers for Special education). Effectiveness of SIT is also enhanced by availability of resources such as teaching learning aids, office and classroom for remediation of the identified learners. Therefore, there is still a great gap between special education recommendation and their implementation in CJSS in Botswana and this hinders the effectiveness of SITs. / Inclusive Education / M. Ed.
