A major challenge confronting psychologists is finding relevant professiona
l development experiences. An Internet-based professional community is one
approach to meeting this challenge. The authors investigated the developmen
t of such a professional community among school psychologists. Results from
behavioral measures and questionnaires reflected a moderate to strong sens
e of community among the participants. The single best predictor of sense o
f community was the participants' perceptions that the Internet site enhanc
ed their professional development. On-line participation and social support
also related to sense of community. Results suggest that the Internet is a
promising medium for the development of professional communities.
