This report implements principal stratification to determine the treatment effect of an educational technology, DragonBox, on middle school algebraic learning. The approach proposes a new solution to the common problem of attrition in the educational sector through the use of principal scores. Findings were modest but indicate the technology may have a positive impact on student learning. This work considers the mathematical trade-off of employing principal stratification and its resultant policy implications.
