The evaluation of behavioral programs requires rigorous measurement and verification. While the randomized controlled trial (RCT) lies at the core of modern program evaluation, in most situations it is not feasible to implement a randomized approach. This is particularly true when programs have gone full-scale and the success of the program needs to be evaluated outside of the confines of an experimental framework involving the random allocation of households to treatment and control groups. This report aims to describe methods for performing a scientifically sound program evaluation in situations where a properly randomized experiment is not possible.
