Since 1981, the Academy of Toxicological Sciences (ATS) has certified toxicologists who are recognized by their peers for their expertise and sound scientific judgment; these toxicologists are awarded the title of Fellow.

The purpose of this recognition and certification is to ensure, through peer review of credentials, the competence and experience of professionals whose work affects public welfare. Candidates for certification must have demonstrated evidence of knowledge of toxicology and active involvement in toxicological activities. A Fellow of the Academy must have an exemplary record of professional accomplishment as well as extensive evidence of recognition by peers of competency and sound scientific judgment in toxicology as reflected by appointment or election to councils, committees, etc.


The vision of the Academy of Toxicological Sciences (ATS) is to be recognized as the leading international organization that certifies toxicologists by peer review of education, professional experience, leadership, demonstrated achievement and scientific expertise.


As a nonprofit organization, the mission of the Academy of Toxicological Sciences (ATS) is to establish a process by which practicing toxicologists are certified based on peer review of the following three focus areas

  • Education, both formal and continuing
  • Professional practice of toxicology
  • Professional recognition
