Your preparation

  • Audit each school's coursework requirements. Biology, chemistry, biochemistry, physics, writing and laboratory work are common, but course and competency policies differ.
  • Prepare for the MCAT where required; check accepted test dates and each school's policy rather than relying on a universal score cutoff.
  • Build sustained clinical exposure and community service. Reflect on what you learned about patients, teamwork and the realities of medicine.
  • Arrange recommendations, transcripts and a thoughtful personal statement. Research can be valuable, but there is no universal required hour count.
  • Explore osteopathic medicine and check whether schools request physician letters or specific osteopathic exposure.

Your application

  • Most US DO schools use AACOMAS; confirm the application service for every school.
  • Complete secondary applications, recommendations and interviews according to the school's instructions.
  • Compare deposit dates and refund rules before accepting offers.

Your training & progression

  • Complete medical school, clinical rotations and the required COMLEX-USA examination sequence.
  • Some students also take USMLE; investigate specialty and residency expectations with an adviser.
  • Enter residency and meet the licensing rules of the state where you intend to practice.

What to weigh before you commit

  • DO is a parallel physician pathway, not a lesser medical credential.
  • Investigate clinical rotation arrangements, accreditation and graduate residency outcomes.
  • International recognition of a US DO degree varies by country; verify with the destination regulator.

Which one, and why

A DO is a fully licensed physician, not a lesser medical credential. DO students sit COMLEX-USA; many also take USMLE for residency. Schools often ask for a letter from a DO.

Who signs your letters

3 to 4 letters, uploaded by the writers through AACOMAS or Interfolio Dossier.

  • 2 science professors required

  • Practising DO physician required

    Most osteopathic schools ask for a letter from a DO who has seen you in a clinical setting.
