Purpose: The International Classification of Functioning (ICF) provides a framework for understanding and accommodating disability. This study examined predictors and outcomes of ICF familiarity among rehabilitation counselors. Method: Analysis of variance and hierarchical regression analysis were used to examine research questions related to ICF familiarity. Results: Rehabilitation counselors with five or fewer years of experience were more familiar with the ICF. Analysis showed familiarity with the ICF positively correlated with greater confidence in recommending work accommodations. Conclusions: Data supports use of the ICF in rehabilitation counseling. Emphasizing the ICF in specific courses (e.g., medical aspects of disability, career and vocational development) may support improved practice.
