The African proverb, it takes a village to raise a child, seems increasingly fitting as problems and complexities of modern life impact the ability to provide healthy settings for the growth and development of children and youth. Psychology has a powerful contribution to make to the creation of "villages" which support and facilitate children's healthy psychological development. The community approach reflects the perspective that individuals are more likely to develop in positive ways when essential core conditions are in place. By infusing knowledge about human behavior, skills in applying this knowledge in specific contexts, and the problem solving processes that scientist practitioner psychologist uses, school psychologists can make a measurable difference in schools. Specific examples of the kinds of activities in which population centered school psychologist would engage include: (1) facilitating the development of interdisciplinary problem solving support structures in schools; (2) strengthening schools' capacity for data based decision making and evaluation of the effectiveness of programs; and (3) collaborating in the enhancement of learning and prosocial behaviors of all children, as well as in the development and implementation of classroom assessment and intervention strategies, based on research but adapted to the specific setting, when problems emerge.
