Changing demographics, a nursing shortage, and various societal changes underscore the need for nurse educators and new nurse educator programs. This article describes a Web-based nurse educator program designed to prepare advanced practice nurses for faculty roles while simultaneously preparing them as clinicians. Guided by adult education theory and self-directed learning theory, the Web-based Nurse Educator Certificate (four Web-based nurse educator courses including a teaching practicum) has been developed and offered to clinical master's and postmaster's students. This article also describes student work with mentors, interactive Web-based teaching strategies, portfolios, graduate competencies, and initial evaluative data. In the first two years of the program, 48 students have taken at least one course in the Nurse Educator Certificate program and eight students have completed it. A Web-based nurse educator certificate program, as part of a clinical master's or postmaster's program, has the potential to help meet the faculty shortage. (C) 2003 Elsevier Inc. All rights reserved.
