The cycle starts the spring before your application year and runs for more than twelve months. These are typical patterns from past cycles — confirm current-year dates on the official service sites before you plan around them.
The MD cycle through AMCAS
If you plan to start medical school in the fall (say, Fall 2027), your AMCAS primary application opens in early May 2026, and you can submit it in early June 2026. The AAMC verifies your coursework — a process that takes longer later in the summer, which is one more reason to submit early — and begins transmitting verified applications to schools in late June. From there:
| When | What happens |
|---|---|
| Early May | AMCAS application opens for filling in coursework, experiences, personal statement, and school list. |
| Early June | Submission opens. Submit as early as you are ready — verification queues lengthen through the summer. |
| Late June | AAMC begins transmitting verified applications to schools; many schools send secondary applications within days or weeks. |
| July–August | Secondary season. Each school's essays and fee are due typically within two weeks of receipt. Turn them around fast and well. |
| September–February | Interview season. Invitations arrive on a rolling basis; interviews may be virtual or in person depending on the school. |
| Mid-October onward | Schools begin offering acceptances. Rolling offers continue through winter and spring. |
| Spring | Final decisions, waitlist movement, and narrowing to one school. Matriculation paperwork and orientation follow in the summer. |
Pre-application checkpoints (the year or two before): finish prerequisite coursework, take the MCAT ideally the spring or summer before you apply, line up letters of recommendation early (writers appreciate months, not weeks), and draft your personal statement well before May.
AACOMAS (DO schools). The American Association of Colleges of Osteopathic Medicine's service runs on a similar summer-through-spring cycle but is a separate application: separate essays (including an essay on osteopathic medicine), its own letter guidelines (many DO schools value a letter from a DO physician), and its own fee structure. Many applicants apply to both MD and DO programs simultaneously — that means two complete primaries and two sets of secondaries, so budget time and money accordingly.
TMDSAS (Texas). Texas public medical, dental, and veterinary schools use their own service, the Texas Medical & Dental Schools Application Service, with an earlier timeline — it typically opens in the spring with a fall deadline that is earlier than AMCAS's. Texas residency matters enormously here (Texas public schools strongly favor Texas residents), and the essays differ from AMCAS's. Texas applicants often apply through both TMDSAS and AMCAS in parallel.
A growing share of applicants take one or more years between college and applying — and it is not a mark against you. A productive gap year typically does one or more of the following:
If you take a gap year, keep two things current: your letters of recommendation (ask professors before you graduate, and confirm they'll still write) and your relationship with your pre-health advising office, which can still support alumni applicants.
Reapplication reality check. Not every applicant gets in on the first try. A reapplication year works best when you can identify what was thin — the MCAT, clinical hours, school list, timing, or essays — and fix at least one thing substantively before reapplying. Applying with the same application twice rarely changes the outcome.
