The purpose of this study was to investigate the effectiveness of a tier two daily behavior card intervention and differential effects based on function of problem behavior. The participants were 36 elementary school students nominated for additional intervention beyond universal School-Wide Positive Behavior Support. Measures included standardized behavior rating scales and rate of office discipline referrals before and after 8 weeks of intervention. A multivariate analysis of variance was used, and results showed statistically significant differences in response to intervention based on teacher-identified function of problem behavior. Results are discussed in terms of considering function of behavior in selecting tier two interventions and implementing a three-tier response to intervention model. (Contains 3 tables and 3 figures.)
