The study sought to evaluate the in-service training received by teachers and the media they used in facilitating learning in the implementation of the policy of automatic promotion in primary schools in Cameroon. The policy divided primary education into three levels; in this scheme automatic promotion takes place within levels and the regular meritorious promotion takes place across levels. Data was collected through questionnaire, classroom observation checklist and interviews, and analysed using inferential statistics, Chi-Square test, thematic analysis and regression analysis. Findings indicated that the provision of in-service training was insufficient to enable teachers accomplish the set policy goals. In the same vein, a majority of teachers reported the inadequacy of the available teaching media to result in effective implementation of the policy.
