Career-technical educators face three issues in credentialing through assessment. First, the occupational credentialing domain is large and evolving, and a clear understanding of it is a prerequisite to considering adoption of a credential. Three types of credentialing are registration, certification, and licensure. Credentialing organizations are categorized by their mission (government regulatory board, trade association, vendor-specific, National Skills Standards Board). Oversight organizations are professional organizations that disseminate information and provide voluntary oversight by evaluating credentialing systems. Second, a set of clear, comprehensive standards is needed to define credential quality and credibility. Proposed evaluative criteria/standards to select assessment-credentialing are marketability, recognition, alignment to curriculum, quality of input standards, quality of assessments, and usability for career-technical education (CTE) setting. Third, CTE policymakers and educators need a rational, efficient process to evaluate credential systems and associated assessments against a set of standards. The following nine steps are the process: (1) define purposes and uses of occupational credentialing systems; (2) set evaluation criteria; (3) identify credentialing systems and evaluate preliminary link to programs; (4) conduct initial screening; (5) determine quality of input standards; (6) determine quality of credentialing assessments; (7) conduct final linkage to curriculum; (8) determine marketability and recognition; and (9) develop data collection procedures.
