ADEA AADSAS Application 2026-27: Dates, Fees and Letters

What is in the dental school application, what it costs and how to keep it from stalling, all from ADEA and Liaison as of October 30, 2026.

ADEA AADSAS is the shared application for US and Canadian dental schools. Per ADEA, the 2026-27 cycle opened May 12, 2026, took its first submissions June 2 and closes February 5, 2027. Liaison lists $264 for the first school and $115 for each one after. Each school sets its own earlier deadline, and ADEA says processing usually takes about four to six weeks.

The service “supports students seeking dental education in the United States and Canada”, for both D.D.S. and D.M.D. degrees. Two groups apply elsewhere: Texas residents applying to Texas dental schools use TMDSAS (see our TMDSAS GPA calculator), and foreign-educated dentists applying to advanced standing programs use ADEA CAAPID. This cycle also moved to a new mobile-first portal, which Liaison calls CAS 3+.

What are the 2026-27 AADSAS dates?

February 5, 2027 is the last possible moment, not your deadline. Check each school under Add Program. You can submit until 11:59 PM ET on its deadline, and “ADEA AADSAS will not send your application to a school if it is received by ADEA AADSAS after the school's deadline.” ADEA's advice: “We suggest submitting your application during the summer”.

Liaison's calendar says transcripts and scores stop matching February 10 at 5 PM ET. ADEA's overview says February 11 is the last day for official documents. Use February 10, the earlier date.

How much does AADSAS cost?

Liaison lists $264 for your first school and $115 for each additional school. Schools may add a supplemental fee of their own. Applicants to Canadian schools pay in full, then get a 25% discount on each Canadian application in late April 2027. Here is the arithmetic, before any supplemental fees.

Fee Assistance Program and PTE costs

The Fee Assistance Program is closed for 2026-27 and reopens in April 2027 for the next cycle. Waivers are limited and first come, first served. Each covers your first three schools, worth $494, and approved applicants get 30 calendar days to use it. For income rules, Liaison points to ADEA's program page, so check there next spring.

Professional Transcript Entry costs $85 for 1 to 3 transcripts, $110 for 4 to 6 and $160 for 7 or more. Fee waivers do not cover it, and ADEA AADSAS no longer offers coupon codes.

What are the four sections of AADSAS?

The first three sections form the core application every school sees. The fourth is set by each school. Dental schools differ on prerequisites, so open every school's page early.

Personal Information

Biographic and contact details, citizenship, race and ethnicity, and the Agreement Statement. This cycle adds a secondary email, a question about factors that affected your academic record and a question about responsibilities outside of being a student. Race and ethnicity now uses seven 2024 Census categories, including Middle Eastern or North African.

Academic History

High schools, colleges, your coursework (entered by you or through PTE) and DAT scores.

Supporting Information

Experiences, achievements, licenses, letters of evaluation and the personal statement. List only experiences from college, up to your top six per category.

Program Materials

Each school's own prerequisites, questions and requirements. Check our dental school requirements guide, then each school's page in the application.

The six experience categories

ADEA collects no resume, so Experiences does that job. Applicants “should limit their entries to the top six experiences in each category.” Neither ADEA nor Liaison publishes a character limit for descriptions in the pages we read, so check the box in your portal.

  • Academic Enrichment: programs run by colleges or nonprofits, such as SHPEP.
  • Dental Experiences: shadowing, preferably a dentist. Name the type of dentist you followed.
  • Employment: paid work outside dental care.
  • Extracurricular Activities: college teams and activities.
  • Research: projects beyond classwork that do not appear as credit on a transcript.
  • Volunteer: unpaid work outside health care.
How to answer the two new questions

ADEA added both this cycle. Keep answers factual: what happened, what you did, what is different now. Be honest and do not over-explain. We wrote these. The applicants are invented.

Are there any factors that may have affected your academic record? In spring 2024 my father's surgery meant I drove him to appointments three days a week, and my grade in organic chemistry fell to a C. I retook the course after he recovered and earned an A-minus, and I have kept a 3.8 science GPA since.

Please explain any other responsibilities you may have outside of being a student. I work 20 hours a week as a pharmacy technician to pay my rent, and I take my younger brother to school each morning. That schedule taught me to plan my study weeks in advance.

The Agreement Statement also asks you to confirm your work is your own, “even if feedback is received from others, including artificial intelligence (AI).”

What is the AADSAS personal statement prompt?

Liaison gives one prompt: “What motivated you to pursue a career in oral health? In your response, you may wish to describe and highlight your strengths, experiences, background, and uniqueness that will contribute to your success in this career.” You get 4,500 characters, counting spaces, carriage returns and punctuation, and the box will not save past that. It goes to every school, so keep it general. “Once you submit your application, the essay cannot be edited or changed.” Paste as plain text with a double return between paragraphs. Our dental school personal statement guide covers what to write.

How do transcripts and DAT scores reach AADSAS?

Official transcripts come from every US and English-speaking Canadian college you list, even if the courses later transferred. Your registrar sends them by mail or through Parchment or National Student Clearinghouse. Posting takes up to five business days after receipt, and processing waits until they are all in.

The American Dental Association sends DAT scores electronically. To match them, enter your DENTPIN in Other Information and your date of birth in Biographic Information. If the ADA confirms it sent them and they are missing at least four weeks after your test date, contact customer service. You can self-report on the current scale, explained in what is a good DAT score.

Should you pay for Professional Transcript Entry?

With PTE, specialists type your completed coursework from accredited schools. You still enter planned, in-progress and foreign courses yourself. It adds time: entry can take up to 10 business days, you then approve it, and verification can take up to 10 more. Self-entry costs nothing extra but carries the risk of mistakes. If your earliest deadline is close, enter it yourself and estimate your GPAs with our AADSAS GPA calculator.

How do AADSAS letters of evaluation work?

You can list up to four. ADEA's two pages differ on committee letters: the letters page allows one committee letter or packet plus up to three individual letters, while the FAQ page says one committee letter plus one. Check what each school wants and confirm with customer service at (617) 612-2045 before relying on more than one extra letter. “Once a reference is completed on the ADEA AADSAS application, it cannot be removed or replaced”, so decide before you send requests.

New this cycle, evaluators answer 13 required relationship and characteristic questions in Liaison Letters, including ratings on 10 attributes: critical thinking, didactic knowledge, integrity, interpersonal skills, professional demeanor, maturity, motivation to pursue dentistry, organizational skills, reaction to criticism and self-awareness. The options are Exceeds expectation, Meets expectation, Not ready at this time and Not observed. Committee letters without agreed ratings and all Interfolio letters use NA/Not Observed, and ADEA says of that: “Applicants should not be overly concerned.”

A note to send your letter writer

We wrote this note. It is not from ADEA. Change the details to fit.

Hi Dr. Lee, thank you for writing my dental school evaluation! You will get an email from ADEA AADSAS with a link to the Liaison Letters portal, so please watch your spam folder too.

The portal has 13 required questions this year, including ratings on 10 attributes such as integrity and critical thinking. Choose Not observed for anything you did not see. You can upload a letter of up to 5 MB, ideally on letterhead and signed.

My earliest deadline is [date], so [date a few weeks earlier] would be perfect. I took your [course] in [term], and my resume is attached.

How long does AADSAS verification take?

Two official answers. ADEA says “it usually takes about four to six weeks to process an application.” Liaison says “Verifications occur in chronological order and can take up to 10 business days to complete.” They count different things in the wording: ADEA from when your materials arrive, Liaison from your Complete status. Neither explains the gap, so plan on six weeks.

During verification, each course gets a subject category, each grade converts to a standard value, GPAs are calculated and degrees are confirmed. Your status then moves to Verified. If significant mistakes turn up, it moves to Undelivered and comes back to you.

What causes an Undelivered application

Liaison lists a college left out, all courses under one term, missing or wrong prefixes and course numbers, missing courses (often labs, PE, withdrawals, test credits and repeats), vague titles, unconverted credits, terms out of order and information that consistently does not match your transcripts. Misspellings, capitalization and up to 4 occasional errors do not trigger it.

Fix each item and click Re-Submit. Verification typically resumes within five business days of returning to Complete. Your submission date stays the same, but your complete date changes, so ask your schools whether that matters.

When should you submit AADSAS?

We suggest submitting at least six weeks before your earliest deadline, with transcripts ordered a week before that. That is our rule, built from the long end of ADEA's estimate. These example deadlines are not any school's. Enter your own.

One trick from ADEA: finish Program Materials for your quickest schools, submit to those to get in the verification line, then add the rest while you wait.

What can you change after submitting?

Most sections lock. Per Liaison, you can edit contact details, add schools whose deadlines have not passed, add evaluations up to the maximum and add new entries in some sections. Existing experiences stay as they are, though you can add new ones.

Academic Update, step by step

The second window runs December 1, 2026 to February 5, 2027. You need at least one school in Verified status by February 5, and you can update grades only once, so wait for final fall grades. Change the term to Completed in Transcript Entry, click Submit My Updates, and order new transcripts only after the confirmation email. Earlier transcripts will not count, and they must arrive by February 10. Verification can take up to 10 more business days.

Reapplying next cycle

Per ADEA, you can carry over personal details, experiences, achievements, licenses and academic history. You redo the release statements, personal statement, letters, program materials and school choices. The 2027-28 application opens May 11, 2027, so print your current one by May 10, 2027.

What will dental schools ask about your application?

Interviewers often start from what you wrote, so be ready to explain each experience out loud. Start with why dentistry and our dental school interview questions, then try this one.

“What experiences have confirmed your interest in dentistry?”

Your AADSAS Experiences section is the raw material. Pick one moment from shadowing, say what you noticed and what it changed, and keep it under two minutes.

Our example answer (we wrote it, not a real applicant)

I thought dentistry was mostly about precise hands until I shadowed a general dentist in a community clinic. A patient had put off care for years because she was embarrassed about her teeth.

The dentist spent the first ten minutes just asking about her and explaining her options. She came back twice more, and on her last visit she smiled in the waiting room for the first time.

That showed me the hand skills matter, but trust is what brings people back. That is the part of dentistry I want to spend my career on.

Frequently asked questions

When does the 2026-27 ADEA AADSAS application open and close?

It opened May 12, 2026, with the first submissions on June 2, 2026. The cycle closes February 5, 2027 at 11:59 PM ET, and all processing ends February 12, 2027. Each school sets its own earlier deadline, and ADEA will not send your application to a school after that school's deadline.

How much does ADEA AADSAS cost?

Liaison lists $264 for the first school and $115 for each additional school, so five schools come to $724. Schools may add a supplemental fee. Canadian schools get a 25% discount, refunded in late April 2027.

How long does ADEA AADSAS verification take?

ADEA says it usually takes about four to six weeks once your application, fee and official transcripts are in. Liaison's help center says verification takes up to 10 business days once your status is Complete. Plan around the longer number.

What is the AADSAS personal statement prompt and limit?

The prompt asks what motivated you to pursue a career in oral health. The limit is 4,500 characters, counting spaces, carriage returns and punctuation. It goes to every school and cannot be edited after you submit.

How many letters of evaluation can I send through AADSAS?

Up to four. ADEA's letters page allows one committee letter plus up to three individual letters, while its FAQ page says one committee letter plus one individual letter. Check each school, and ask ADEA AADSAS customer service if you plan to send a committee letter plus more than one other.

How do I send my DAT scores to AADSAS?

The American Dental Association sends them electronically, and paper copies are not accepted. Enter your DENTPIN in Other Information and your date of birth in Biographic Information so they match. If scores are missing at least four weeks after your test date and the ADA confirms it sent them, contact customer service.

Can I change my AADSAS application after submitting?

Only in limited ways. You can edit contact details, add schools whose deadlines have not passed, add new evaluations up to the maximum and add new entries in some sections. You cannot edit the personal statement or existing experiences, though you can add new ones.

Who uses TMDSAS or CAAPID instead of AADSAS?

Texas residents applying to Texas dental schools use TMDSAS. Foreign-educated dental graduates applying to advanced standing programs use ADEA CAAPID.
