New release of Session 4 of NAMs - Use and Applications of (Q)SAR and Read-Across

We are thrilled to announce the release of the new version of Session 4 of our eLearning course "NAMs - Use and Applications of (Q)SAR and Read-Across". This session, titled "Interpretation of (Q)SAR", offers comprehensive insights into the principles and frameworks essential for understanding and applying (Q)SAR models effectively.

This session is designed to provide you with the knowledge and tools necessary to critically evaluate (Q)SAR models and predictions, ensuring their effective application in regulatory and hazard assessment contexts. Whether you are a seasoned professional or new to the field, this course will enhance your understanding and capabilities in using (Q)SAR methodologies.

The course is recognised by EUROTOX for 16 hours of Continued Professional Development (CPD) for ERT accredited toxicologists.
