Fiscal resources are becoming tighter, and school districts are asked to do more with less funding. This is occurring at the same time that school psychologists require increased professional development around effective practices and advocacy for bilingual students. Communities of practice (CoPs) are one potential solution as they aim to bring together various professionals into a working relationship around their common interests. They also bring stakeholders into the work of state education agencies as allies and bring fresh approaches to persistent problems by uniting decision makers, practitioners, and consumers around a common goal (IDEA Partnership, 2014). This article describes the creation and progress of the Colorado Bilingual School Mental Health CoP. The history, challenges, strategies, and outcomes are shared with an effort to encourage others to create CoPs to influence educational reform, particularly with traditionally underserved populations such as bilingual/bicultural populations.
