Applicants must meet the following initial criteria to become a candidate for examination:
- A graduate of a college or university with an earned doctoral degree in a biomedical discipline. Applicants without doctoral degrees must possess a baccalaureate degree in a health science discipline, such as pharmacy or nursing, followed by a minimum of five years of full-time professional experience in applied clinical toxicology. Scholastic coursework is not considered to be professional experience.
- Because the American College of Medical Toxicology and the American Board of Veterinary Toxicology are responsible for certification in their respective areas, applicants holding the Doctor of Medicine, Doctor of Osteopathy, or Doctor of Veterinary Medicine degree are not eligible to sit for the ABAT examination.
- Completion of at least 12 months of post-doctoral training (i.e., residency or fellowship) in clinical toxicology or a closely related field. Applicants without post-doctoral training must have a minimum of at least three years of professional experience related to applied clinical toxicology after completion of their doctoral degree. To be prepared for the examination, candidates should have considerable clinical experience and an understanding of the clinical and environmental factors associated with various types of toxicological problems. Examples of activities related to the practice of applied clinical toxicology include consulting with medical personnel on patient care issues, administrative responsibility for a poison control center with consultative responsibilities, rendering opinions on product toxicity, teaching clinical toxicology to students, practitioners or colleagues, collaborating with medical toxicologists, and research in applied clinical toxicology.
- Applicants must demonstrate experience in all the areas of clinical, research and teaching activities, and leadership. An abundance of experience in one area will not substitute for lack of experience in another.
- Applicants holding a degree in a health care profession in which licensing is required must be in good standing with the appropriate jurisdictional board and must be eligible for, or possess, a valid, unrestricted license to practice. A copy of the license must accompany the application.
- Applicants must be members in good standing of the American Academy of Clinical Toxicology at the time of their application.
