To deliver interventions completely and consistently (i.e., with adequate treatment integrity) and, thus, have a positive impact on student outcomes, implementers, such as teachers and paraprofessionals, often require support. To efficiently deliver implementation support, school psychologists could embed research-based strategies into their typical consultation. This article describes two implementation support strategies, direct training and implementation planning, which target implementer skill and intervention logistics, respectively. The delivery of these supports is illustrated in the context of a randomized case study that focuses on increasing a teacher's use of best practices in classroom management. In addition to teacher treatment integrity data, student outcomes are assessed. Implications for school psychologists are described and resources related to classroom management and treatment integrity are provided.
