A country can train its labor force for skilled and semi-skilled occupation in many ways. However, assertions have been made regarding the relative merits of different types of vocational training. It has been argued that the more formal types of training provided by vocational secondary schools lead to better trained personnel who are more in demand in the labor market because they offer the employers greater productivity (World Bank, 2003). Others have argued that much of the training provided by formal educational method is not vocational in nature, and that in fact, workers can be provided with the training necessary to be semi-skilled or skilled craftsmen in considerably less time and at lower cost through other modes (Harbison, 1973).
