How to Sign Up for the Casper Test: Registration Walkthrough

Signing up for Casper sounds like a five-minute task, and mechanically it is. But the registration flow contains several one-way doors — the wrong test type, a mismatched name, a missing school on your distribution list — that are annoying or expensive to walk back. This walkthrough covers each registration step in order, the mistakes that actually cost applicants money or deadlines, and what to double-check before you pay.

Before You Register: Three Things to Confirm

First, confirm you actually need Casper. Requirements change every cycle, and programs list them on their own admissions pages. If you're applying to US medical schools, cross-check the list of schools requiring Casper. Some schools require AAMC PREview or Duet instead of or alongside Casper, and taking the wrong assessment helps no one.

Second, know your test type. Casper isn't one test; it's a family of them, split by country, profession, and sometimes language. US Medicine (MD/DO), Canadian Medicine, nursing, PA, dentistry, and other professions each have their own test code, schedule, and distribution list. Registering under the wrong one is the single most common sign-up mistake, and you usually discover it when a school on your list doesn't appear at checkout. Applicants in nursing and PA programs should check those guides for their specific requirements.

Third, have your program list ready. You'll select score recipients during registration, and while you can add distributions later for a fee, you can't remove them for a refund. A settled school list before you sign up keeps you from paying for distributions you don't need.

Step-by-Step: Registering on Acuity Insights

1. Create an account at Acuity Insights (takeCasper became acuityinsights.app). Use the same legal name and email address as your program applications. Schools match your Casper score to your file by these details, and a mismatch, such as a nickname or an old email, can delay score matching while you sort it out with support.
2. Select your country, profession, and test type. This determines everything downstream: available dates, fees, and which programs you can send scores to. If a school on your list is missing from the distribution options, stop; you're probably in the wrong test type.
3. Pick a test date. Sessions run roughly every two to three weeks, with extra availability from August through October. Work backward from your earliest program deadline, allowing 2-3 weeks for score delivery. The test dates guide covers how to choose in detail. You must reserve at least 3 days before the session for ID verification and payment processing.
4. Select your score distributions. Every program you add here receives your score automatically once results process; you cannot preview your quartile first. Add every school you're realistically applying to now, since adding later costs extra per program.
5. Pay and confirm. For US Medicine, the base fee is $85 USD plus roughly $18-20 per additional distribution; fees vary by country and test type. If you qualify for the AAMC Fee Assistance Program or an Acuity partner waiver, upload proof in the portal before checkout so reduced pricing applies. Check the confirmation email's date, time, and time zone against your own calendar.

If You Need Accommodations, Register Early

Accommodation requests, such as extended time or additional breaks, need to be submitted at least three to four weeks before your preferred test date, with clinical documentation. Approved accommodations unlock a separate bank of sessions, and those seats can fill quickly. If this applies to you, the accommodations process, not the standard calendar, should drive your registration timeline. Full details, timelines, and documentation requirements are in the Casper policies guide.

After You Register: What Happens Next

Registration unlocks Acuity's free practice materials inside your account, which run in the same interface as the real test. Complete them once, early, so the mechanics hold no surprises.

Then build a real practice schedule between now and your date. One sitting per cycle means there's no do-over, so the weeks between registration and test day are your entire preparation window. The preparation guide lays out a step-by-step plan, and the free practice test roundup lists every no-cost resource worth your time, including StudyCasper's 5 free timed scenarios and typing test.

A week before your session, run Acuity's system requirements check on the exact device and browser you'll use, and walk through the test day checklist so a webcam issue never eats your one sitting of the cycle.

Changing or Cancelling a Registration

Life happens, and the rules are strict enough to know in advance:

• Rescheduling: allowed up to ten calendar days before your session, subject to seat availability on the new date.
• Cancelling: a full refund requires cancelling at least ten days ahead. Inside that window, the fee is generally nonrefundable without a documented medical or technical emergency.
• Lateness: arriving more than fifteen minutes late typically counts as a no-show. You lose the fee and, because Casper allows one sitting per cycle, the chance to test again until next cycle.
• Adding schools: you can add distributions after registering (per-program fee applies), but you can't remove paid ones for a refund.

Frequently Asked Questions

How far in advance do I need to sign up for Casper?

Acuity requires reserving at least 3 days before the session, but registering several weeks ahead is safer: popular sessions fill up, and you want the practice window anyway. If you need accommodations, start three to four weeks out at minimum.

How much does it cost to sign up for the Casper test?

US Medicine runs $85 USD base plus roughly $18-20 per additional program distribution. Fees vary by country and test type, and fee assistance is available for eligible applicants through the AAMC FAP or Acuity partner waivers.

What name and email should I use to register?

The same legal name and email as your program applications. Schools match your score to your application file using those details, and mismatches can delay verification.

Can I change my Casper test date after signing up?

Yes, up to ten calendar days before your session, if another date has open seats. Inside ten days, the fee is generally nonrefundable except for documented emergencies.

Do I pick which schools get my score when I sign up?

Yes, and every program on your distribution list receives your score automatically once it processes. You can't preview results first, and paid distributions can't be removed for a refund, so finalize your school list before registering.

The Bottom Line

Signing up for Casper is simple if you settle three things first: whether your programs require it, which test type applies to you, and which schools belong on your distribution list. Register under your exact application name, book at least a few weeks out, and treat the confirmation email's time zone as something to verify, not assume. Then use every week between sign-up and test day on actual preparation, because the one-sitting-per-cycle rule means registration is the only easy part.
