About the ToxMSDT Learning Resources
These free lessons were developed for undergraduate students and other learners. Materials include modules, which provide overviews of areas within toxicology, and case studies, which give learners the opportunity to explore specific toxicology-related issues. The engaging content facilitates toxicology knowledge acquisition and data analysis skills development. Those who demonstrate content mastery receive a certificate of completion.
These resources were developed for Toxicology Mentoring and Skills Development Training (ToxMSDT) with support from the National Institute of General Medical Sciences of the National Institutes of Health, awards R25GM113989 and R25GM139200.
We invite faculty who are using these materials in their courses to let us know which materials you are using by completing this form.
