The growing diversification of the kindergarten through twelfth grade (K-12) classroom presents unprecedented challenges that will alter the ways in which school social workers, counselors, and psychologists function in school systems. Education reform continues to breed greater competition for diminishing resources and will ultimately reduce the collective network of services provided by the integration of roles and responsibilities among related services personnel. In a solution-focused presentation, the authors will examine ways in which school social workers, counselors, and psychologists can meet and exceed the challenges of increasing diversity in school systems through culturally competent collaborative practice. The authors will demonstrate how collaboration and coordination among related services personnel can address the increasing diversity of public grade school systems to enhance practice efficacy, facilitate teaching and learning, devise evaluation research, and reduce the duplication of services.
