Medical Toxicology Certification

Eligibility Criteria for Certification in Medical Toxicology

The American Board of Pediatrics (ABP), in collaboration with the American Board of Emergency Medicine (ABEM) and the American Board of Preventive Medicine (ABPM), offers a certificate in Medical Toxicology. This document provides the requirements of the ABP. (Note: A candidate who has a primary certificate from one of the other two boards should contact that board for its eligibility criteria.) Examination registration dates may differ for each board.


Certification by the ABP

A candidate for medical toxicology certification must have achieved initial certification in general pediatrics and continue to maintain general pediatrics certification in order to take a medical toxicology certifying examination. No exceptions to this policy will be granted. The requirements for Maintenance of Certification (MOC) can be found on the ABP website: All candidates are urged to ensure that the requirements for MOC will be met in sufficient time to allow acceptance to the subspecialty certifying examination. 


An applicant must hold a valid, unrestricted allopathic and/or osteopathic medical license in at least one jurisdiction in the United States, its territories, or Canada. If licenses are held in more than one jurisdiction, all licenses held by a physician should meet this requirement. Temporary or training licenses are not acceptable. The option to fulfill the licensure requirement using a non-US or non-Canadian license no longer exists 


Two years of fellowship training must be completed in a program accredited in medical toxicology by the Accreditation Council for Graduate Medical Education. No continuous absence of more than one year will be permitted. 

Absences from Training
No continuous absence of more than one
year will be permitted. Due to the potential for significant changes in medicine over time, the Credentials Committee must review requests for previous credit when a fellow has interrupted fellowship for more than 12 months.

Combined absences/leaves in excess of two months during the two years of training, whether for vacation, parental leave, illness, and so forth, must be made up. For information regarding waiving time for parental, medical, caregiver leave, please visit the ABP Absences from Training Policy .

An applicant must satisfactorily complete all subspecialty training before the first day of the month in which the examination is administered. An applicant whose contracted training period does not expire before the first day of the month of the examination will not be eligible for that examination, even if all formal training has been completed earlier and the remaining time is used only for leave.

No credit will be given for subspecialty training during core general pediatric residency or a chief residency.

A fellow engaging in part-time training, must complete the required training on a part time basis not to exceed four years.

An applicant seeking certification in another pediatric subspecialty or a non-ABP specialty (eg, pediatric emergency medicine or emergency medicine) on the basis of practice and/or training may not apply the same period of time toward fulfillment of these requirements.

Verification of Training

An applicant will be asked to list the program(s) where fellowship training occurred as well as the name(s) of the program director(s). The ABP will require the program director(s) to attest to the fellow’s competence. The role of the program director in the certification process is to verify completion of training and evaluate clinical competence, including professionalism.

An applicant must have the verification of training on file at the ABP in order to be admitted to the subspecialty examination. If an applicant’s training is not verified or if the applicant receives an unsatisfactory evaluation in any of the competencies (with the exception of professionalism alone), the applicant will be required to complete an additional period of subspecialty fellowship training before reapplying. The director of the program where the additional training occurred must complete a separate verification. If the unsatisfactory evaluation is in professionalism only, the applicant will be required to complete an additional period of fellowship training or, at the program director’s recommendation and at the ABP’s discretion, a period of observation may be required in lieu of additional training. A plan for remediation must be submitted for review and approval by the ABP.

Appeals Process: Applicants who wish to appeal evaluations must proceed through institutional due process mechanisms. The ABP is not in a position to re-examine the facts and circumstances of an individual’s performance.

Transfer of Fellowship Training: For continuity of training experiences, mentoring, and assurance of meeting training requirements, it is best that a fellow complete all training in the same program. Occasionally, a fellow may need to transfer to another program for compelling reasons. In such circumstances, it is incumbent that the program director(s) of the current program and the proposed program communicate to ensure that the fellow who transfers will meet all requirements if he or she desires to apply for a certifying examination in the subspecialty.

Time-Limited Eligibility for Initial Certification Examination

Beginning with the examinations administered in 2014, the ABP will require that applicants have completed the training required for initial certification in the pediatric subspecialties within the previous seven years (eg, 2007 or later for examinations administered in 2014). If the required training was not successfully completed within the previous seven years, the applicant must complete an additional period of supervised practice in order to apply for certification. The subspecialty examinations are offered every other year. Therefore, please note that the pediatric subspecialty examination may not be offered in the year the acceptance expires. The full policy can be found on the ABP website:

Closure of Practice Pathway

The ABP has established a policy for a closure date for the practice pathway for all subspecialties in which a certificate is offered. The certifying examination in 1999 was the last examination for which an individual could apply for certification in medical toxicology using practice experience accrued by the deadline stated in the original eligibility criteria when the subspecialty was established. Please contact the ABP if additional information is needed.

It should be noted that these criteria and conditions are subject to change without notice. All applicants are advised to contact the ABP to ascertain whether the information they have is current.
