This qualitative study addresses teacher perceptions of using positive behavior interventions and supports (PBIS) as positive behavioral interventions. This phenomenological study was conducted within a Pre-K-5 elementary school in northwestern North Carolina. In order to collect qualitative data, personal individualized interviews were conducted from a purposeful sample of teachers in the school who have experience implementing more intensive positive behavioral interventions. By analyzing data derived from the interviews and classroom and individualized documentation, the researcher was able to identify themes such as teachers' perceptions in regards to using PBIS as a behavioral intervention. Themes elaborating on the ways that teachers implement PBIS in their classroom as well as the most consistently used elements of the PBIS framework also emerged from this study. Findings from this study will be useful in helping to implement the PBIS framework to fidelity as well as helping to sustain these practices. This information will be vital in training new teachers that join the staff as well as veteran teachers who are struggling with individual students' behavior.
