This article draws on previously employed methods for conducting fidelity studies and applies them to an evaluation of an unprescribed intervention. We document the process of assessing the fidelity of implementation of the Math Recovery first-grade tutoring program, an unprescribed, diagnostic intervention. We describe how we drew on recent…

In this paper, the authors describe a case of measuring implementation fidelity within an evaluation study of Math Recovery (MR), a pullout tutoring program aimed at increasing the mathematics achievement of low-performing first graders, thereby closing the school-entry achievement gap by enabling them to achieve at the level of their…
