The purpose this study was to examine the implementation of The Leader in Me, a school-wide positive behavior intervention system (SW-PBIS), and analyze its impact on 5th grade students based on student achievement and office discipline referrals in a rural elementary school in North Central Washington state. The school was in the first year of implementation when the study was conducted. Full implementation of the program was expected to require three to four years. Nevertheless, the researcher was interested to analyze results within the first year of implementation. The results of the study demonstrated that, when compared to baseline data, there was no discernible difference for office discipline referrals or student achievement during the first year of implementation of The Leader In Me. In order to understand the long term effects of the program, more information will need to be gathered over an extended period of time.
