Impact Evaluation in Practice

This book from the World Bank provides a detailed introduction to impact evaluations in the development field. It also provides a number of tools and approaches for conducting impact evaluations.

"The approach to impact evaluation in this book is largely intuitive, and we attempt to minimize technical notation.
