ABSTRACT
Educators and society at large find it increasingly important to evaluate the various contributions made to education. This is because of the general desire to safeguard the highest possible educational quality and also to ensure that money is invested in a way that yields the highest possible educational output. Evaluation is a general educational concern with some special implications for distance education. The purpose is usually to find out to what extent teaching and learning lead to expected results and acceptable standards. The knowledge acquired by evaluation studies can be used as a basis for improving the teaching-learning system as well as for describing and judging it.
