The Fifth Edition of this bestselling book has been thoughtfully revised to make it the most useful and comprehensive resource in evaluation research today. New to this edition is: more coverage on meta-analysis, particularly in regard to its use in design and modification of programme intervention; revised and expanded coverage on programme monitoring and management; new chapters on quasi-experimental impact assessments; assessment of full-coverage programmes including a comparison of the differences in these procedures; and more examples and boxed exhibits of local and state evaluations.

The effective organization of the Fourth Edition has been retained, mirroring the way evaluation is practised - from diagnosis of a problem with a social programme through to the final stages of measuring and analyzing a specific programme.
