Authenticity is an important element of new modes of assessment. The problem is that what authentic assessment really is, is unspecified. In this article, we first review the literature on authenticity of assessments, along with a five-dimensional framework for designing authentic assessments with professional practice as the starting point. Then, we present the results of a qualitative study to determine if the framework is complete, and what the relative importance of the five dimensions is in the perceptions of students and teachers of a vocational college for nursing. We discuss implications for the framework, along with important issues that need to be considered when designing authentic assessments.
