Abstract: Treatment integrity refers to the degree to which intervention plans are implemented as designed. In practice, documenting treatment integrity is critical for the accurate evaluation of interventions. Before valid decisions can be made regarding the effectiveness of an intervention, problem-solving teams must know with some degree of confidence whether or not the intervention was implemented as intended. This article describes the importance of monitoring treatment integrity, the challenges associated with monitoring integrity, and specific strategies to promote high levels of integrity for academic interventions.
