This study examined the feasibility and integrity of a daily report card (DRC) intervention in a small sample of randomly assigned elementary students with previously diagnosed ADHD and classroom impairment. In order to enhance implementation, a conjoint behavioral consultation approach was used in which parents were engaged as active participants in the treatment. Intervention parents and teachers maintained moderately high levels of adherence over 4 months based on multiple methods of implementation assessment, and acceptability ratings were all very favorable. Intervention participants demonstrated significant improvement in academic skills and productivity at post-test as compared to control participants, with moderately large effect sizes. Results suggest that a DRC intervention implemented within conjoint parent–teacher consultation may help to reduce the research to practice gap in evidence-based school interventions.
