Fidelity of implementation is a critical but often neglected component of any new system, practice, or intervention in educational research and practice. Fidelity is a multidimensional construct focused on providing evidence of adherence, quality, dosage, differentiation, and responsiveness following implementation. Unfortunately, fidelity has not always been prioritized, although evidence suggests that is changing, at least in published research. Further, although there are myriad methods for measuring fidelity, psychometric evaluations of fidelity tools have been limited, except in the SWPBIS literature. Calls for a science of fidelity have been made (Gresham, 2017) and are beginning to be answered. Overall, there appears to be more research focused exclusively on fidelity, including measurement approaches, psychometric evaluations, and relation to outcomes. As this research expands, we hope that the broad use and integration of fidelity in practice follows. We believe that the days of neglecting fidelity are behind us in education and see fidelity playing a central role in education moving forward. Through reliable and valid measurement of fidelity, scalable evidence-based practices can be developed and proliferated, positively impacting students’ academic and behavioral outcomes.
