Readiness for change, defined as "the cognitive precursor to the behaviors of either resistance to, or support for, a change effort" (Armenakis, Harris, & Mossholder, 1993), can serve as a facilitator or barrier to dissemination of evidence-based services. Limited research has been conducted to understand the role of readiness for change in educational contexts and its relationship to the success of evidence-based school mental health (SMH) initiatives. The current study examined three community's (i.e. teachers, school mental health staff, and principals) readiness for change in schools from the perspective of three key informant groups. Participants were recruited from 11 elementary schools in Ohio and included school administrators (n=13), teachers (n=194), and school mental health staff (n=47). All participants completed a modified version of Change Orientation Scale (COS; Kearney & Smith, 2009), and answered questions about their use of a specific positive behavior support strategy and their participation in a recent school mental health initiative. Replicating previous work, the subscales of the COS exhibited good to excellent internal consistency (αs = .85-92). Results demonstrated variability in COS scores across schools, suggesting that COS scores may be used to identify schools that are ready for adoption of a new initiative. Differences were detected among informant's perceptions of readiness and among community readiness levels.
