In Ghana and globally, continuous professional development (CPD) is most essential for promoting teacher learning and improving school effectiveness, but it is a field of progressive opportunities and research. This study therefore seeks to investigate the development and impact of the attitudes of CPD programmes to teachers and also sought to gather the impact of CPD on both their classroom practices and wider professional life in schools. A qualitative approach was adopted and the study was undertaken using questionnaires. Through purposive sampling, the study was able sample out 50 respondents. It can be read from the study that the teachers strongly disagree that CPD is a waste of time to teachers. Again, the study came out that the impact of CPD changes teachers’ knowledge and practice, provides opportunities for teachers to explore new roles. Also, CPD helps to refine teaching practice and broaden teachers experience and enhances teachers’ effectiveness with students. It was reviewed that male teachers are likely to benefit more from taken CPD than female teachers. The analyses also reviewed that the youthful people are the majority of teachers in the Yendi community, therefore CPD will equip more teachers if much attention and opportunity is given to them to develop themselves professionally. It was recommended that teacher’s negative attitudes towards CPD needed to be changed It was also recommended that there is a need to invest more time and resources into the implementation and development of CPD.
