The purpose of this paper is to describe best practices in designing and implementing strong quasi-experimental designs (QED) when assessing the effectiveness of policies, programs or practices. The paper first discusses the issues researchers face when choosing to conduct a QED, as opposed to a more rigorous randomized controlled trial design. Next, the paper documents four sets of best practices in designing and implementing QEDs including: (1) considering unobserved variables, (2) selecting appropriate matching strategies for creating comparison groups, (3) following general guidelines for sound research, and (4) addressing the What Works Clearinghouse (WWC) standards. The paper then presents 31 frequently-asked questions related to QEDs meeting WWC standards with reservations and discusses common pitfalls that cause studies not to meet WWC standards. Topics covered in the frequently asked questions section include: study design/group formation, outcomes, confounding factors, baseline equivalence, sample loss and power, and analytic techniques. The paper provides a detailed checklist of issues researchers should consider when designing a strong QED study, and discusses why each issue is important and how it relates to WWC standards. One appendix is included: Checklist for Quasi-Experimental Designs; Study Design Characteristics to Consider.
