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, as reflected on the ATS application form:

  1. Education, both formal and continuing;
  2. Professional practice of toxicology as evidenced by scholarly publications and non-published technical reports and integrated analyses, editorial services to scientific journals, participation on external and internal toxicology-related committees, professional society membership(s), scientific presentations, attendance at scientific meetings, teaching responsibilities, etc.; and
  3. Professional recognition reflected by career advancement, elected and/or appointed service with national and international professional/technical committees and review bodies, invited presentations, and professional honors and awards.

ATS not only certifies toxicologists by peer review of their professional achievement, but also imposes a code of ethics that assures that ATS Fellows who participate in research and testing, determine safety, risk and risk-benefit, and who make regulatory decisions that impact public health and the environment, exercise sound scientific judgment, free of bias and based on the scientific data.


Since 1981, the Academy of Toxicological Sciences (ATS) certifies 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.

Professional Expectations of Fellows

Fellows of the Academy are generally engaged in the following:

  • Research leading to an understanding of the processes involved in biological responses occurring from exposure to chemical, biological, or physical agents.
  • Evaluation and integrated interpretation of the human health implications of data describing toxic effects occurring in humans or experimental animals resulting from exposure to chemical, biological, or physical agents.
  • The application of toxicological data to the development of health and environmental standards protective of human health.
