This document provides an overview of programme evaluation (PE) as presented by Cosme Zinsou Odjo. It defines PE as an ongoing process that examines the interaction of theory and practice in vocational education and training (VET) programmes. PE has three perspectives - planning, implementation, and conclusion/diffusion. Effective PE requires describing the subject, design, actors, and criteria. The main purposes of PE are legitimation, broadening knowledge, and promoting dialogue. PE should utilize empirical research methods and be integrated into ongoing project activities in a formative way. The document also discusses personal views on improving PE by making it more collective, relevant, and considering different evaluators, tools, and criteria.
