AADSAS Timeline: When to Apply for Dental School

AADSAS opens in mid-May and submission begins in early June. Here is the practical timeline for the dental school cycle, including DAT scheduling and interview prep.

ByElias Woodbury·
Key Takeaways
  • AADSAS opens in mid-May and allows submission starting in early June. Schools begin receiving applications in mid-June.
  • Submitting in June or July is meaningfully better than submitting in October at rolling-admission dental schools.
  • Take the DAT 4–6 weeks before submission so your scores arrive with your application, not after.

12 Months Out: Foundation

The year before AADSAS opens, focus on what cannot be rushed:

  • Complete prerequisites (vary by school but commonly include 1 year of bio, gen chem, organic chem, physics, biochemistry, English)
  • Continue dental shadowing across 2+ practice types
  • Build relationships with science faculty for LOEs
  • Begin DAT prep (target 2–4 months of dedicated study)

Spring: DAT and Letters

Spring is the heaviest preparation phase:

  • February–March: Ask for letters of evaluation. Provide writer packets with deadlines.
  • March–April: Take the DAT. Aim for completion 4–6 weeks before you submit AADSAS so scores arrive with the application.
  • April: Polish personal statement (4,500 characters). Build school list. Send transcripts to AADSAS.

May–June: Submit

AADSAS opens in mid-May. Submission begins in early June. Schools begin receiving applications in mid-June.

  • Submit AADSAS in early to mid-June if your application is polished.
  • Order transcripts immediately — transcript delays are the most common cause of late verification.
  • Verification typically takes 3–6 weeks during peak season.

July–October: Secondaries

Most dental schools send supplemental applications within 2–6 weeks of AADSAS verification. Supplementals vary widely: some are short fee + form, others include multiple essays.

Return each supplemental within 2 weeks of receipt. Track due dates carefully — a few schools have hard deadlines as early as October 1, while most are December 1.

Fall–Winter: Interviews

Most dental school interviews run from August through February. Many schools use rolling admissions, so earlier completion produces earlier interview offers. Acceptances begin December 1 (the earliest most dental schools may issue acceptance offers per ADEA Policy on Acceptance and Confirmation).

The ADEA Traffic Rules govern timing of acceptances and deposits across most US dental schools. Review them carefully so you do not lose deposits or holding positions by accident.

Frequently Asked Questions

AADSAS opens in mid-May for the upcoming cycle. Submission begins in early June, and schools begin receiving applications mid-June.

Take the DAT in April or May of your application year so your scores are official by the time you submit AADSAS. Taking the DAT after submission delays your application becoming complete at each school.

AADSAS verification typically takes 3–6 weeks during peak season (June–August). Schools cannot review your application until it is verified, so early submission shortens this lag.

Most dental school interviews run from August through February. Many schools use rolling admissions, so early interview offers convert to earlier decisions.

AADSAS itself remains open through late winter, but individual schools have their own deadlines — some as early as October 1, most by December 1. Applying in October at a school with a December deadline is technically allowed but not strategic.
