Training for researchers using animals is a requirement in most European countries. However, somewhat surprisingly, the main actor in providing specific guidelines for such training is a scientific society - the Federation of European Laboratory Animal Science Associations. FELASA is also presently the only entity that accredits training courses on an international level. At the Institute for Molecular and Cell Biology, we have been running courses following the FELASA recommendations for Category C (scientists) since 2005. Since 2008, these courses have been run under accreditation. In this presentation, I will share our experience as course organizers, with focus on the implications and benefits of the accreditation program.
