The chapter explores converging international forces that provide the context for future development of school psychology, examines the current status of school psychology internationally, and proposes a model for guiding future development of the profession on a global level. A primary reason for universal insufficiency of mental health services for children and adolescents is shortage of mental health professionals such as school psychologists, due in part to the shortage or lack of professional development programs. Critical to the advancement of school psychology internationally is development of a theoretical and empirical basis for training and practice that addresses cultural and contextual diversity. Drawing on models for international development and prior work of the authors, a model for the cultural construction of international school psychology is proposed. Key features of the model include ongoing research and evaluation, and partnership with local stakeholders to facilitate capacity building and sustainability of local programming.
