School-wide positive behavioral support (SWPBS) programs are becoming an increasingly popular and effective way to reduce behavioral disruptions in schools. Results from a 4-year study examining the effects of an SWPBS program in a public elementary school indicated significant reductions in percentages of behavioral referrals, suspensions, and instructional days lost, but the effect sizes were small. Implications for school counselors and future research are discussed. (Contains 2 tables.)
