Purpose: To identify the current training needs of state-federal rehabilitation counselors and determine if the self-perceived training needs differ for participants who are a certified rehabilitation counselor (CRC) to those counselors with out the CRC credential. Method: A mixed-methods internet-based survey design was utilized and included descriptive, qualitative, and ex post facto approaches on a sample of rehabilitation counselors (N = 341) via the Knowledge Validation Inventory-Revised (KVI-R). Results: The participants reported high or moderate self-perceived training needs on 9 of the 10 content areas on the KVI-R; however, no significant differences between certified and non-certified rehabilitation counselors were found. Highest degree earned and numbers of years in practice were significant predictors of training needs. Conclusion: The results from this study indicate a self-reported need for additional training of state-federal rehabilitation counselors in many of the CORE knowledge domains considered essential for rehabilitation counseling. The findings also indicate that as level of education and experience increased among this sample, the need for training decreased.
