When I sat on the admissions committee at Mount Sinai, I saw strong applicants lose months because of a missing letter of recommendation, an MCAT score that arrived in September, or a late submission date. Even if these applicants were stellar, they lost out on interviews and acceptances because they weren't organized when applying to medical school. After nearly two decades of guiding applicants at MedEdits, I am convinced that the single best predictor of a smooth cycle is an applicant who knows exactly what must be gathered, entered, verified, and submitted, and who checks each item off before the application systems open.
This checklist should serve as a companion to our medical school application timeline. The timeline tells you when each phase happens. This page tells you what you need in hand at each phase, section by section, for AMCAS, AACOMAS, and TMDSAS. If you are still building your candidacy and want to know which courses, GPA, and MCAT scores schools expect, start with our guide to medical school requirements and return here once you are ready to apply.
I have organized the checklist in the order you will actually work through it: decisions and accounts first, then documents, then the application itself, then a pre-submission audit, and finally everything that happens after you click submit. Print it, copy it into a spreadsheet, or work through it on screen, but do work through every line.
Phase 1: Accounts and Decisions to Settle Before the Application Opens
The application systems open in early May, and I tell every applicant to treat the opening date as the real deadline. All medical schools review applications on a rolling basis, so the decisions below should be made in the winter and early spring of your application year, not in June.
| Checklist Item | What It Involves | Done |
|---|---|---|
| Decide whether you are truly ready to apply | Apply only when your academics, MCAT, and clinical, service, and research experiences are where they need to be. A gap year is often the wiser choice, and our guide to taking a gap year before medical school explains how to use one well. | ☐ |
| Apply for the AAMC Fee Assistance Program (if eligible) | FAP benefits are not retroactive, so apply and receive approval before you register for the MCAT or submit AMCAS. Approved applicants receive reduced MCAT registration fees, AAMC prep materials, MSAR access, a PREview fee waiver, and an AMCAS fee waiver for up to 20 schools. | ☐ |
| Take the MCAT early enough | Most schools will not review your file until all pending scores arrive. I advise taking the MCAT no later than June of your application year, and earlier is better. If you are not ready, a later test date will delay your entire cycle, which is a strong signal to consider waiting a year. See our MCAT scores guide. | ☐ |
| Choose your application systems | AMCAS for MD programs, AACOMAS for DO programs, and TMDSAS for Texas public medical schools. Many applicants use two or all three. If you are weighing osteopathic schools, read our DO vs. MD comparison. | ☐ |
| Meet with your premed advisor or committee | If your school writes a committee letter or sends a letter packet, learn its internal deadlines now. They often fall in the winter, months before AMCAS opens. Keep your advisor informed throughout the cycle. | ☐ |
| Build a preliminary school list | Compare your GPA and MCAT with each school's matriculant data, consider state residency, and note medical school mission fit. Our guide on how to use the MSAR walks through the process. | ☐ |
| Identify required situational judgment tests | Some schools require Casper, some require AAMC PREview, and some require neither. Check each school on your list and schedule the tests you need early. Our Casper test prep guide explains the format. | ☐ |
| Set up one professional email address | Schools contact you by email, and your address is often a reviewer's first impression of you. Use a simple variation of your name and check it daily for the entire cycle. | ☐ |
| Budget for the full cycle | Primary application fees, secondary fees, situational judgment tests, and interview costs add up quickly. Fees for each system appear in the comparison table below. | ☐ |
Phase 2: Documents and Materials to Gather
Everything in this phase can be prepared before the application opens. Below are all of the documents you will need to apply to medical school.
| Checklist Item | What It Involves | Done |
|---|---|---|
| Personal copies of every transcript | You will enter every course exactly as it appears on your official transcripts, including withdrawals, failures, repeats, and courses removed under a grade forgiveness policy. That includes community college courses, dual enrollment courses taken in high school, and summer programs. Keep your own copies so your entries are accurate. | ☐ |
| Confirmed letter writers | Most schools expect two science faculty letters and one non-science faculty letter, or a committee letter, and many value a letter from a physician or research mentor. Ask in the winter or early spring and give each writer your CV and personal statement draft. Our medical school letter of recommendation guide covers whom to ask and how. | ☐ |
| Completed work and activities list | For every activity, record the dates, average weekly hours, total hours, and the name, title, and contact information of someone who can verify it. Schools do contact these people. | ☐ |
| Drafted experience descriptions | AMCAS allows up to 15 Work and Activities entries of 700 characters each, and up to three of them can be designated Most Meaningful with an additional 1,325 characters. Our AMCAS Work and Activities guide shows how to write them. | ☐ |
| A finished personal statement | The AMCAS personal comments essay allows 5,300 characters including spaces. Plan on several drafts. See our medical school personal statement guide. | ☐ |
| Program-specific essays (if applicable) | MD/PhD applicants write two additional essays and TMDSAS has its own personal statement (5,000 characters) and additional essays. | ☐ |
| Disclosure details (if applicable) | If you have an institutional action or legal history, gather the dates and documents and draft a factual, accountable explanation. Never omit a required disclosure. Schools may run background checks, and an omission is far more damaging than the original event. | ☐ |
| Background and family information | The biographic section asks about your parents' education and occupations, childhood residence, and family finances. If you plan to describe any impactful experiences, draft that essay, too. | ☐ |
Phase 3: AMCAS Section by Section Checklist
The AMCAS application has nine sections. Reviewers generally read them in this order, so by the time a committee member reaches your personal statement, they already know your academic record and your activities. Keep that in mind when you decide where to explain a red flag.
| AMCAS Section | What to Have Ready | Done |
|---|---|---|
| 1. Identifying Information | Legal name, any alternate names (which must match your MCAT record and transcripts), date of birth, and AAMC ID. | ☐ |
| 2. Schools Attended | Every college you attended, plus your institutional action history and any prior medical school matriculation. Request an official transcript from each institution as soon as AMCAS opens, using the AMCAS transcript request form. | ☐ |
| 3. Biographic Information | Contact information, citizenship, state of legal residence, languages, family background, childhood information, optional disadvantaged status essay, and felony and misdemeanor questions. | ☐ |
| 4. Course Work | Every course, grade, and credit hour, entered exactly as shown on your transcripts and classified by subject. AMCAS calculates your GPAs, including your BCPM GPA, from these entries. | ☐ |
| 5. Work/Activities | Up to 15 entries and up to three Most Meaningful designations. For the 2027 cycle, AMCAS renamed the Social Justice/Advocacy experience type to Community Health Advocacy, so categorize those entries accordingly. | ☐ |
| 6. Letters of Evaluation | Up to 10 letter entries. A committee letter or letter packet counts as one entry. Generate a letter request form for each entry and share it with each writer or your prehealth office. | ☐ |
| 7. Medical Schools | Your school designations, any Early Decision Program choice, and letter assignments for each school. Each school can receive a different combination of letters. | ☐ |
| 8. Essays | Your personal comments essay and, for MD/PhD applicants, the MD/PhD and significant research experience essays. | ☐ |
| 9. Standardized Tests | MCAT scores release to AMCAS automatically. List any future test dates so schools know a score is pending. | ☐ |

AMCAS, AACOMAS, and TMDSAS: What Changes on Your Checklist
The three systems ask for similar materials, but they differ in ways that trip applicants up every year. The two mistakes I see most often are assuming MCAT scores will reach AACOMAS on their own and assuming every system handles letters the same way.
| Item | AMCAS (MD) | AACOMAS (DO) | TMDSAS (Texas public) |
|---|---|---|---|
| 2026-2027 cycle opened | May 5, 2026; submission began May 28; first transmission to schools June 26 | Early May 2026 | May 1, 2026; submission began May 15 |
| Application fee | $180 including one school; $48 per additional school | $198 including one school; $60 per additional school | $230 flat, regardless of number of schools |
| MCAT scores | Released automatically | Not automatic; you must request release through the AAMC | Confirm that TMDSAS has received your scores |
| Letters | AMCAS Letter Service; up to 10 entries assigned by school, letter dossier service, or school letter packet | Through AACOMAS or sent directly to schools; check each school's requirements | Submitted to TMDSAS; letters due October 15 |
| Processing | Verification takes longer at peak volume; AAMC posts current processing times | Verification time varies with volume; submit early | Typically 2 to 4 weeks |
| Fee assistance | AAMC FAP waives fees for up to 20 schools | AACOMAS fee waiver program | TMDSAS does not grant fee waivers |

Texas applicants should also know that TMDSAS uses a match for Texas residents, with school preference rankings due in late January and match results announced in February. Our TMDSAS guide covers the Texas essays and activity categories in detail.
Phase 4: The Pre-Submission Audit
Transcript discrepancies are one of the most common causes of verification delays, and a delay of even a few weeks moves you behind thousands of other applicants in the rolling review queue. Before you submit, work through this audit line by line.
| Checklist Item | What to Confirm | Done |
|---|---|---|
| Course entries match transcripts | Compare every course, grade, and credit hour against your own transcript copies. Confirm that transfer credit appears under the institution where you originally took the course. | ☐ |
| Transcripts requested from every institution | AMCAS will not verify your application until every official transcript arrives. The forgotten community college or summer session transcript is the classic culprit. | ☐ |
| Letters assigned correctly | Each school receives the letters it requires, and a specialty letter (an MD/PhD research letter, for example) goes only where it belongs. Letters can arrive after submission, but follow up with any writer who has not uploaded. | ☐ |
| Essays and descriptions proofread | Paste each essay into the application and check formatting, because special characters and line breaks sometimes change. Have someone you trust read the final version in the system. | ☐ |
| Experience contacts verified | Every contact is current and knows they may be contacted. | ☐ |
| School list finalized | You can add schools after submission, but schools see your application only once it is transmitted, so a complete list at submission avoids losing time. | ☐ |
| Disclosures complete and accurate | Institutional action and legal questions are answered truthfully, with explanations that are factual and brief. | ☐ |
Phase 5: After You Submit
The work that follows your application submission often determines whether you receive interviews. Our guide to AMCAS verification explains what happens to your application immediately after you submit.
| Checklist Item | What It Involves | Done |
|---|---|---|
| Pre-write secondary essays | Many schools reuse their prompts from year to year. Use our secondary essay prompts to draft answers while you wait for verification. | ☐ |
| Return each secondary efficiently, but don't rush your work | Most schools send secondaries to every applicant, while others screen first. Either way, a prompt turnaround shows interest. Track each school's fee and deadline. See our guide to the medical school secondary application. | ☐ |
| Complete Casper or PREview | Schools that require these tests often will not consider your file complete until scores arrive. | ☐ |
| Confirm each file is complete | Check each school's applicant portal for missing items. A file stuck at "incomplete" is not being reviewed. | ☐ |
| Prepare for interviews | Prepare for traditional, panel, and multiple mini interview (MMI) formats, many of which are now virtual. Our medical school interview guide is the place to start. | ☐ |
| Send updates and letters of intent when appropriate | Significant new accomplishments and, later in the cycle, a letter of intent to your top choice can help, but only for schools that accept them. | ☐ |
The Checklist Mistakes I See Most Often
The most costly mistake is treating official deadlines as real deadlines. Primary application deadlines run from the fall into December, but because schools review on a rolling basis, applicants who submit near those deadlines are competing for a small number of remaining interview spots. I advise every applicant to treat the day the application opens as the deadline and to submit within the first few weeks.
The second mistake is underestimating how long the application takes. Some applicants who are not accepted in their first cycle had the grades, scores, and experiences to succeed but ran out of time to write strong essays, request transcripts, and return secondaries promptly. In the same way you built a study plan for the MCAT, build a written plan for the application, and start it in January.
The third mistake is assuming one system's rules apply to all of them. The applicant who submits AMCAS and AACOMAS on the same day but forgets to release MCAT scores to AACOMAS will sit in an incomplete queue at every DO school on their list. Read each system's applicant guide in full, and keep it open while you work.
Finally, I see applicants stop at submission. Your primary application earns you a secondary, but your secondary essays, your interview, and your follow-up communications earn you the acceptance. Keep this checklist open until the day you commit to a medical school.
If you would like a physician to review your materials and plan before you submit, our team of physician advisors can help. You can schedule a free consultation to discuss your application.
Frequently Asked Questions
What do I need to apply to medical school?
You need official transcripts from every college you attended, MCAT scores, letters of evaluation (usually two science faculty letters and one non-science letter, or a committee letter), a personal statement, descriptions of your experiences, and an application through AMCAS, AACOMAS, or TMDSAS. After you submit, most schools also require secondary applications, and some require Casper or AAMC PREview.
Can I submit my application before my letters of recommendation arrive?
Yes. AMCAS and TMDSAS both allow you to submit before your letters arrive, and letters are added to your file as they are received. Schools generally will not consider your file complete until the letters they require arrive, so follow up with your writers early.
Do I need to report courses I withdrew from or retook?
Yes. AMCAS requires you to list every course you attempted, including withdrawals, failures, and repeated courses, even if your school removed the original grade under a forgiveness policy.
Are MCAT scores sent automatically to every application system?
No. MCAT scores release automatically to AMCAS, but AACOMAS requires you to request that the AAMC release your scores. Confirm that TMDSAS has your scores as well.
When should I submit my medical school application?
As early as you can submit a polished application, ideally within the first few weeks after submission opens. Because schools review applications on a rolling basis, an early application has access to more interview spots. Our medical school application timeline lays out every phase month by month.
