The purpose of this study was to analyze the effects of a school wide positive behavior initiative designed to improve student behavior. Researchers analyzed the last 3 years (2005-2008) of student discipline referral data for grades 7 and 8. Implementation resulted in a significant reduction in the number of discipline referrals. Data revealed a decrease of 23% in the number (2239 vs. 1723) of discipline referrals from year one to year two and a decrease of 22% in the number (1723 vs.1340) of discipline referrals from year two to year three. Results obtained from the analysis indicate that the TBSI was effective in improving student behavior in a rural middle school. (Contains 1 table and 4 figures.)
