A Comparative Assessment

This paper presents the methodologies used to build up a program evaluation. Several types of methodologies and techniques on program evaluation can be found in the literature composing a valuable reference base for the evaluator. By presenting the various methodologies we do not aim to measure their efficiency and propose the best one. On the contrary we believe that each methodology has some advantages and, moreover, in some cases it could be the most appropriate. The aim of this paper is the summarizing of different approaches in evaluation, the gathering of various methodologies and the determination of specific circumstances under which each methodology is the most appropriate to follow. A more ambitious aim is to propose some interesting methodology mixes, which can be useful guides when looking for evaluation designs that fit better in the reality of a program.
