The purpose of this paper is to provide an overview of the World Health Organization ICF model and to discuss how this model can be used as a framework for assessing service outcomes that goes beyond the use of employment as indicator of success in vocational rehabilitation (VR) agencies. Specifically, we advocate for the development of a comprehensive taxonomy of outcome measures based on the ICF model to assess the effectiveness of medical, psychological, educational, and vocational services provided by VR to improve functioning. activity, and participation level of people with disabilities in the rehabilitation process. Ling this taxonomy of outcome measures, we can assess the effectiveness of services provided directly by rehabilitation counselars and those services that are provided by vendors as well as the overall effect of these services on employment outcome, health status, and quality of life of consumers of vocational rehabilitation services.
