Following release of the OECD No 23 Advisory Document in July 2022, a team was set up to assess whether the guidance provided impacted Charles River Safety Assessment existing practices. As an organization we are expected to align with the expectations outlined in OECD No 23.  The training will enable personnel to gain an understanding of OECD 23 and explain what we are doing as an organization to comply with OECD No 23- if asked by our colleagues, customers or during a regulatory inspection.  The training is pertinent to Testing Facility / Test Site Management and QA Personnel (QAP), across Charles River Laboratories OECD sites.
