The 2012 Integrated Early Childhood Development (IECD) curriculum recently introduced in all Botswana government preschools was examined by this study. To guide the findings of this study the literature addressing the effective preschool curriculum implementation strategies was reviewed. Furthermore, structured interviews, non-participant observations and documents review were conducted in line with the qualitative phenomenological research approach. Specifically, teachers from three preschools implementing the 2012 IECD curriculum framework were interviewed to obtain their views with regard to its implementation. The data collected from the interviews was thematically analysed and triangulated with that from the observations and documents. The findings of this study showed that even though the teachers were generally satisfied with their different levels of training, they were concerned about the limited duration of in-service training as well as the course content that did not address their unique needs and those of their supervisors. Consequently, effective IECD curriculum implementation was negatively affected by lack of effective supervision as well as lack of teaching resources and other forms of support. Drawing from the findings of this study, recommendations were made and teacher training guidelines were developed. The guidelines were informed by the SCLT (teacher training) and CoP (formation of partnerships) theories. The implications of this study are that the suggested training guidelines would promote teacher efficacy facilitated by proper teacher training strategies and they will hopefully motivate the formation of working partnerships. / Curriculum and Instructional Studies / M.
