This document provides guidance to study authors about how to describe regression discontinuity design studies and report their findings in a way that is clear, complete, and transparent. The first two sections detail the descriptive information, and the third section describes the data that WWC reviewers use to assess studies. The fourth and final section details the additional descriptive information that WWC reviewers use to assess regression discontinuity design studies with multiple, pooled, or aggregated impacts.

This document does not include information about how studies are judged against WWC design standards. For information about the WWC review process and design standards, please refer to the WWC Procedures and Standards Handbooks.
