The professional portfolio: an evidence-based assessment method.

Competency assessment is critical for a myriad of disciplines, including medicine, law, education, and nursing. Many nurse managers and educators are responsible for nursing competency assessment, and assessment results are often used for annual reviews, promotions, and satisfying accrediting agencies' requirements. Credentialing bodies continually seek methods to measure and document the continuing competence of licensees or certificants. Many methods and frameworks for continued competency assessment exist. The portfolio process is one method to validate personal and professional accomplishments in an interactive, multidimensional manner. This article illustrates how portfolios can be used to assess competence. One specialty nursing certification board's process of creating an evidence-based portfolio for recertification or reactivation of a credential is used as an example. The theoretical background, development process, implementation, and future implications may serve as a template for other organizations in developing their own portfolio models.
