HOW DOES COMPLEXITY IMPACT EVALUATION? AN INTRODUCTION TO THE SPECIAL ISSUE.

In recent years, the evaluation of complex interventions has been of great interest to members of the evaluation community. In this special issue of the Canadian Journal of Program Evaluation, we explore how evaluators, in their practice, approach the evaluation of complex interventions. The aim of this issue is not to provide exhaustive coverage of all the different ways of evaluating complex interventions, but rather to inform practitioners on the experiences of seasoned evaluators.
