There is an increasing need for education professionals to keep abreast of new research and developments in their fields. The peer support group, which is characterized by the sharing of expertise and knowledge, the provision of mutual support, and joint problem solving among professional colleagues, has been advanced as promising means of promoting professional growth and development. This article reports the results of an exploratory national survey of school psychologists' involvement in peer support groups (PSGs) that was undertaken to identify the potential contributions of such activities to improving professional practice. Nearly 64% of the respondents indicated involvement in a PSG at some point in their careers, with almost 50% currently participating in one. Several benefits were attributed to group membership, and it was suggested that further research efforts are needed to clarify the essential components that contribute to group effectiveness.
