Initiatives in the recognition of prior learning (RPL) have been taken in Sweden in recent years, mainly focusing on prior vocational learning among immigrants. The government started different projects to find methods for recognising a person's prior learning in the field of vocational competence. This article presents a study of how these projects were organised and their starting points. Differences are identified concerning whether they were integrated with, or parallel to, the school system, and whether the starting point was a few vocations or a number of different vocations (depending on the background of the participants). The article then looks at some problems that arise when trying to recognise prior learning. We find that knowledge of the Swedish language is essential in this process, but that the demands are flexible and the criteria informal. The article also discusses the relationship between RPL and the educational system, where most of the projects had problems in not being too influenced by the school tradition where the main documentation of competence is grades. Finally, the article discusses conditions for the development of trust in RPL. (Contains 1 figure and 5 notes.)
