This study sought to investigate the perception of teachers on the effectiveness of in-service education and training (INSET) at the basic schools in Akatsi South District of Ghana. It also sought to find out how often in-service training programmes were organized in the district and how effective the training programme were. A descriptive cross-sectional survey was used in carrying out the investigation using a sample of 60 teachers in Akatsi District of Ghana. Also, stratified random sampling and purposive sampling techniques were used in selecting the respondents. The main instruments for data collection were questionnaire and interview. The study revealed that majority of the teachers perceived or rated INSET programmes organized for them as being adequate and very effective with regards to teaching and learning in the district. On the other hand, most of the head-teachers (70%) debunk the assertion made by the teachers that INSET programmes were very effective with regard to teaching and learning in the district. They were of the view that most teachers who attend in-service training did not perform effectively in their work with regard to understanding pupils’ errors, enhancing teachers’ knowledge, preparing effective lesson notes, selection and use of appropriate TLMs and interpreting the curriculum concerning teaching and learning in the district. It was recommended among others that the organizers of in-service training programmes in Akatsi district look for qualified instructors who understand the needs of the teachers to handle the various subject areas during INSET programmes and place more emphasis on the professional skill development aspect of the teacher.
