Recently, I worked with a client on a grant proposal. In the RFP, the funder stipulated that the evaluation study should have a quasi-experimental design--that is, if a full-blown experimental design was not possible. (The randomized controlled trials, or RCTs, that you've heard bandied about take precedence.) As the emails went back and forth, I realized that the funder's expectations were opaque. It was an opportunity to educate my client. Here's a brief sponsored by UNICEF that explains what a quasi-experimental design is, when you might use one, and how. Take a look and let me know if you have questions or thoughts about how you might use the methods. I'd be curious to know.
