The OECD webinars on Testing and Assessment Methodologies focus on selected ongoing projects that will result in the short to medium term in new methodologies to test and assess chemicals. These free webinars are open to potential end users among regulators and contract research organisations who want to get familiar with new standards and approaches. Video recordings of our webinars are made available online afterwards.
Webinar series on testing and assessment methodologies
The OECD webinar series is dedicated to testing and assessment methodologies, bringing together experts worldwide to share best practices among regulatory authorities and the scientific community. It serves as a platform to explore and discuss current projects aimed at developing new testing and assessment methodologies for chemicals in the near to medium term.
