The report relates to discussions held on operational and financial aspects of test methods validation under the OECD Test Guidelines Programme. The workshop was organised in the context of a broader discussion on building confidence of regulatory bodies and modernising the validation process for new and emerging chemical safety testing methods and approaches. In this workshop, attention was raised on the need for increased public funding for validation activities, including independent peer review, and the need to make existing validation resources and know-how better known to method developers to facilitate the organisation of validation activities.
