Negative student behaviors are increasing in schools today (Molly et al., 2013). When students engage in problem behaviors, they are more likely to fall through the cracks and their educational gap increases. Therefore, something needs to be done in school systems to decrease these problem behaviors. PBIS is an implementation framework that is designed to improve academic and social behavior outcomes for all students (Sungai & Simonsen, 2012). The purpose of this literature review is to explore the effects of PBIS on student behavior and ways to implement PBIS successfully. Overall, research shows that when PBIS is implemented correctly and with fidelity, negative student behaviors decrease because of this preventative framework.
