There is increased emphasis on using experimental and quasi-experimental methods to evaluate educational programs; however, educational evaluators and school leaders are often faced with challenges when implementing such designs in educational settings. Use of a historical cohort control group design provides a viable option for conducting quasi-experiments in school-based outcome evaluation. A cohort is a successive group that goes through some experience together, such as a grade level or a training program. A historical cohort comparison group is a cohort group selected from pre-treatment archival data and matched to a subsequent cohort currently receiving a treatment. Although prone to the same threats to study validity as any quasi-experiment, issues related to selection, history, and maturation can be particularly challenging. However, use of a historical cohort control group can reduce noncomparability of treatment and control conditions through local, focal matching. In addition, a historical cohort control group design can alleviate concerns about denying program access to students in order to form a control group, minimize resource requirements and disruption to school routines, and make use of archival data schools and school districts collect and find meaningful.
