Eligible professional practice:

  • Clinical supervision, precepting or mentoring of clinicians and students
  • Telehealth and volunteer clinical care related to travel medicine
  • Administrative oversight involving advanced practice providers or faculty

Documentation required if audited:

  • Paid practice: a letter or email signed by the applicant’s immediate supervisor, preferably on organizational letterhead, confirming at least 1,500 qualifying practice hours during the five-year cycle. Multiple letters may be submitted if the applicant changed employers.
  • Self-employed practice: a notarized statement confirming at least 1,500 qualifying practice hours during the five-year cycle.
  • Volunteer practice: an official letter or other documentation from the sponsoring organization describing the qualifying duties and dates of service.

Pathway B: Professional Activities

Pathway B requires 50 CE points plus 50 professional activity points. Applicants may earn the 50 professional activity points from one, two, three, or all four categories. There is no minimum number of points required in any individual category. All activities must relate directly to travel medicine and the ISTM Body of Knowledge.

Self-Reporting and Audit Process

Applicants self-report completion of the applicable renewal requirements. They do not need to submit a detailed list of every CE program or professional activity with the initial application. The CPD Committee randomly audits 10 percent of CTH renewal applications each year.

If selected for audit, the applicant must provide documentation supporting the active professional license and all claimed renewal requirements, including CE points and either Pathway A professional practice hours or Pathway B professional activity points. Applicants should retain supporting records and may upload and store renewal documentation in their ISTM portal. If an audit identifies missing information or ineligible credit, ISTM will notify the applicant and provide an opportunity to submit additional materials before the application is rejected.

Continuing Education Documentation

CE certificates should include the applicant’s full name, course title, completion date, provider name, and number of CE points awarded. All submitted CE must relate directly to travel medicine and the ISTM Body of Knowledge.
