This study aimed at finding out the perceptions of secondary school mathematics teachers who had attended in-service training under Secondary Science Mathematics Teachers’ programme. A mixed methods approach was used in this study and data was collected using a survey questionnaire and focus group discussion. Findings from this study indicate that most teachers perceive the programme to have positively impacted on their teaching skills i.e. towards the implementation of the main objectives of SESMAT in-service training. For in-service training to be effective and greatly impact on teachers, their welfare needs to be taken care of in terms of allowances. New innovations for instance, area of ICT need to be incorporated in the training programme.
