Background to the StudySustaining continuous professional development (CPD)programmes is an equally important agendum as initiating the practice of CPD. It is said that the end justifies the means to connote the importance of the results / products / dividend / outcome of any investment. Thus, the resultant effect of any adventure proves the worth of the investment therein. It is only when such professional ventures are sustained to become part of the systemic institutional culture that the needed impact would be made on the lives of beneficiaries as the primary beneficiaries of the effect of such engagements, the students, are in a continuous turnover with new crops immerging when earlier enrollees are exiting as a result of completion on their courses. This makes it very difficult for any well-meaning educational leader to comfortably sweep under the carpet the topical issue of continuous updates of the knowledge stock of the workforce. Even in the 18 th century when Adam Smith propounded Human Capital Theory (HCT), the ideology drove on the assumption that formal education was very necessary and highly instrumental in improving the productivity of any population (Almendarez, 2010). This ideology lives on making human capital development an essential good across nations and periods.According to Psacharopoulos and Woodhall (1997), the provision of formal education is seen as an investment in human capital and therefore the proponents of the HCT have considered education as worthier than that of physical capital.
