This resource gives a quick overview of some of the main evaluation designs used for outcomes evaluations or impact evaluations. These are evaluations that aim to answer questions about whether a program, service or treatment (often called the ‘intervention’) is working as intended, or if it is having a positive or negative effect on its intended audience.

The resources also briefly discusses some other types of evaluation design that are sometimes used in outcomes evaluations but are also commonly used to evaluate how programs or services are being delivered.

This resource is intended for use by program managers or practitioners who want a basic understanding of the different types of evaluation design.
