This study was designed to measure instructional design competencies as a result of participation in a 9-month Web-based training program called "Roadmap to Effective Distance Education Instructional Design." The researchers used a self-assessment pre- and posttest to determine participant initial and final competence in 12 areas: adult learning, understanding teaching at a distance, instructional design, course development, delivery strategies for teaching at a distance, instructional technology resources, advanced interaction methods, accessibility, planning and conducting evaluation, evaluation analysis and reporting, administrative issues, and training and support. Open-ended verification narratives were analyzed using the constant comparative method. This competency model worked well to document learning as a result of participation in the program.
