Now in paperback, this volume summarizes, compares and contrasts the work of seven major theorists of programme evaluation. The authors develop a conceptual framework against which specific criteria of certain theories can be tested. They present the theoretical and practical advice of the theorists and critiques of their work. The conclusion summarizes the areas of agreement and disagreement between these influential theorists and offers directions for a new theory of programme evaluation.
