One study has examined the month-to-month effectiveness of the daily report card (DRC) intervention for students with disruptive behavior, yet these findings have not been replicated. With a sample of 37 student-teacher dyads (Kindergarten-5th grade), we sought to replicate previous findings with an independent sample and advance the literature by using a nonparametric effect size (ES) that accounts for baseline trends, examining academic and behavioral DRC target behaviors separately, and examining differences between optimal and suboptimal intervention responders. Replicating findings from the previous study, large improvement in behavioral and academic DRC target behaviors was demonstrated in the first month of intervention, with small incremental gains and/or maintenance of effects observed in months 2, 3, and 4. Differences assessed between optimal and suboptimal responders were not statistically significant. However, trends, particularly those for optimal and suboptimal responders to behavioral targets on the DRC, suggest that teacher consistency in responding to classroom rule violations is an important variable for future study. The results replicate previous findings and suggest important directions for future research on classroom intervention implementation and intervention decision making.
