| Abstract: Cluster Randomized Trials (CRT) are being increasingly used in program evaluation. In contrast to standard experiments, not individuals are being randomly assigned to an intervention versus control group, but entire groups of people (clusters). This roundtable will discuss the design and analysis of cluster randomized trials and, the policy and practical implications of using such designs. The roundtable will focus on particular technical details such as effect sizes as well as the potential negative unintended side effects of the requirement to use more rigorous research designs. |
