The effect of School Wide Positive Behavior Support (SW-PBS) on teacher morale was examined using the Purdue Teacher Opinionnaire (PTO). Faculty members of two rural Tennessee middle schools participated. The treatment group experienced initial implementation of a SW-PBS program and was both pretested and posttested. The middle school where the control group taught was posttested without implementation of SW-PBS. A paired t-test was applied to analyze the data, showing improvements at a significance level of .05 in the factors of facilities, rapport with the principal, and community pressures. Findings suggest that teachers are likely to have increased levels of morale relating to these three factors when a SW-PBS program is implemented.
