A brief narrative description of the journal article, document, or resource. The ever-changing requirements of working life require individuals to develop their competencies throughout their life cycle. This lifelong learning paradigm requires a renewed vision concerning assessment in which, besides formal learning, informal and non-formal learning experiences are also recognized. To support this lifelong learning paradigm, procedures have been developed worldwide to assess and credit prior learning experiences (APL). While research on APL stresses the importance of a high-quality standard, so far the literature has applied only a psychometric quality framework. However, from the perspective of APL, where, besides prior knowledge and skills, competencies need to be measured, it is more appropriate to use a combination of the psychometric and edumetric quality criteria. This article will analyze and describe the relationship between quality criteria and the characteristics of APL. The results have revealed that quality criteria based on both are fundamental for APL, but that some criteria are more recognized than are others. Based on this analysis, design guidelines for APL have been formulated.
