OAT Test Dates and Registration 2026–2027: Fees, DENTPIN, Prometric Scheduling, and Retest Policy

Unlike exams with fixed national test dates, the OAT is offered year-round at Prometric testing centers — you pick the date that fits your preparation. That flexibility is great, but the registration process has several steps (and several fees), and getting the order wrong can cost you weeks. Here's the complete walkthrough.

Testing Windows: When Can You Take the OAT?

The OAT has no fixed test dates. It's administered year-round at Prometric test centers across the United States and Canada, subject to seat availability at your chosen location. In practice, this means:

• You can schedule your exam for almost any weekday (and some Saturdays) throughout 2026 and 2027.
• Popular testing windows — late spring and summer, when most pre-optometry students test — fill up first. Book 6–8 weeks ahead if you're targeting May–August.
• Your eligibility window (the period during which you must test) is set when your application is approved. If your plans slip, a one-time 45-day eligibility extension is available per application.

When should you test? Most students take the OAT in the spring of junior year or the summer between junior and senior year, so scores are ready for the optometry school application cycle (which typically opens in summer). Work backwards: give yourself the 12-week prep runway from OAT study schedule 3 month, then add a 2–3 week buffer in case you want a retake before applications are due.

Registration: Step by Step

Step 1: Get Your DENTPIN

Before anything else, you need a DENTPIN (Dental Personal Identification Number) — the ADA's universal ID for dental and optometry admissions testing. You'll use it to apply, schedule, and retrieve your official scores.

• Register for a DENTPIN on the ADA's website with your legal name and personal details.
• Triple-check your name and birthdate. Prometric will deny you admission if your ID doesn't exactly match your registration.
• If you've previously registered for the DAT, you already have a DENTPIN — use the same one.

Step 2: Submit Your OAT Application and Fee

With your DENTPIN in hand, complete the OAT application through the ADA portal. You'll provide:

• Personal and contact information (again — verify it matches your ID exactly)
• Academic background details
• Your selection of optometry schools to receive your scores
• Accommodation requests, if applicable

Then you pay the testing fee. The OAT fee is approximately $535 USD (non-refundable, non-transferable) — it has risen most years, so confirm the current figure on the ADA's OAT page before you budget. The fee covers test administration, an unofficial score report at the test center, and official score reporting to every school you listed on your application.

Money-saving tip: list every school you're considering on your initial application. Score reporting to listed schools is included in the fee. If you add schools later, each additional score report costs approximately $45 per recipient.

Step 3: Receive Eligibility and Schedule With Prometric

After submission, the ADA reviews your application — eligibility confirmation typically arrives within one to two business days by email. That email confirms you can schedule your exam, usually starting 24 hours after receipt.

You then book your appointment directly with Prometric:

• Schedule online through Prometric's website or by phone.
• Choose your test center, date, and time from available seats.
• You'll receive a confirmation notice — keep it. Prometric confirmations are required if you later need to reschedule.

Step 4: Test Day

• Arrive at least 30 minutes early with valid, unexpired government-issued photo ID.
• Your name and birthdate on your ID must match your registration exactly.
• You'll get an unofficial score report before leaving the center.
• Official scores reach your selected schools in approximately 2–4 weeks.

All the Fees in One Place

Fee figures are approximate and based on the most recently published schedules; the ADA and Prometric adjust them periodically — verify current amounts during registration.

The rescheduling table deserves emphasis: moving your date costs real money, and the price climbs steeply as test day approaches. Don't book a date you're not committed to. If you're unsure you'll be ready, book later rather than paying $150 to push it back.

Retest Policy

You can take the OAT three times without any special permission. Beyond that, the ADA's rules tighten:

The retest policy is not subject to appeal. And remember: schools see your full testing history through your DENTPIN. The strategic implication is clear — don't use your first attempt as a "practice run." A low first score followed by a strong retake tells a fine story, but three attempts with flat scores tells a worse one than a single solid 330.

When to retake: only if you're confident you can gain at least 10–20 points on your Academic Average. Diagnose why you underperformed first — was it content, pacing, or test-day nerves? — because retaking without fixing the cause just buys you the same score twice. See what is a good OAT score for help deciding whether your score is worth defending or worth retaking.

Fee Waivers

The registration fee is steep, and the ASCO (Association of Schools and Colleges of Optometry) offers a 50% partial fee waiver for qualifying students. If cost is a barrier, look into the waiver before you register — it applies to the registration fee and can save you over $250. Check the ASCO or ADA site for current eligibility criteria and application steps.

Next Steps

Once your date is locked in, build your preparation around it: follow the 12-week plan at OAT study schedule 3 month, and make sure you're studying with materials that match the real exam — compare options at OAT prep.
