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.

Training and orientation on validation of methods at the OECD
This webinar is an introduction to the validation of
in vitro methods which explains why validation is important in the context of OECD Test Guidelines. The modular approach to validation is explained, the optimal design of an inter-laboratory study is presented, common hurdles and how to address them, and important resources are shared. This webinar is for individuals who are not yet familiar with validation and have questions about its utility in the regulatory context.
Becoming familiar with method readiness evaluation
This webinar is for researchers who have developed a new method and wonder if it is ready to be used outside their laboratory. You will hear experience of research teams who have evaluated the readiness of a large set of in vitro methods, and experience of an organisation that regularly evaluates readiness of a method before embarking on inter-laboratory testing.
