Case review

Each DACT applicant must complete three clinical case reviews demonstrating superior management skills within the scope of their licensure or certification. These case reviews will follow a prescribed template and adhere to HIPAA privacy compliance guidelines. 

If case reviews are rejected, detailed explanations will be provided with reference citations and suggestions for further research. Rejected case reviews can be resubmitted within 3 months without repeating the exam application.




DACT applicants must supply one professional character endorsement. This endorsement can come from a variety of sources including:

  • A fellow ACT member
  • A member in good standing of any professional thyroid organization
  • A member in good standing of any professional endocrine organization

DACT Certification is kept current by paying the two-year certification fee, maintaining ACT membership in good standing, and completing a minimum of two ACT continuing education training modules per year. 

If a DACT member lapses on certification and less than three years have lapsed since the last certification, he/she can renew their certification by completing a minimum of two ACT continuing education training modules per year lapsed, payment of the certification fee, and successful submission of one case review per certification guidelines. If three years have lapsed since DACT membership renewal, members will be considered eligible to sit for another certification exam, assuming all conditions are still met.
