This paper will review and describe the use of 'virtual' (i.e., persons interacting in different geographic locations) technologies in clinical supervision. First, a rationale for using such technologies as a tool for doing clinical supervision will be presented. Second, a review and description of available technological resources will be offered. These include: e-mail, computer-mediated communication (CMC), videoconferencing (VC), Internet or World Wide Web, and WebTV. Third, some of the settings that have utilized such technological resources in conducting clinical supervision (i.e., psychiatry, medicine, education) and therapy will be reviewed. Ethical issues in using these technologies and implications for supervision will be explored.
