DO Schools That Require CASPer: The Verified 2026–27 List

Which DO schools require CASPer?

These four are the only osteopathic programs in Acuity's Dates and Fees tool for the 2026–27 US cycle, checked November 14, 2026. Each school's admissions page confirms the requirement.

All four distributions accept the English test only and accept Acuity's Fee Assistance Program.

Remaining CASPer dates for DO applicants

The 2026–27 US Medicine schedule began on March 19, 2026. As of November 14, three sittings remain that any of these schools accept:

• Thu, Dec 3, 2026 · 8:00 PM EST
• Tue, Jan 5, 2027 · 6:00 PM EST
• Tue, Feb 9, 2027 · 8:00 PM EST

If Sam Houston is on your list, December 3 is your sitting. It is the last one Sam Houston accepts, and its distribution deadline is December 16. Acuity recommends booking at least three days ahead and asks for accommodation documents four weeks before your test, so accommodation requests for December 3 are already past that window. All dates by test type are in the CASPer test dates guide.

School-by-school details

Sam Houston State University COM (Texas)

Sam Houston's how-to-apply page lists the Acuity Casper assessment among its requirements and says applicants must submit both the supplemental application and the Acuity assessment to be considered for an interview. Applications go through TMDSAS, which opens May 1 and closes October 1; the school's supplemental application, with a $75 fee and no fee waivers, is due December 1. In Acuity, enter your TMDSAS number.

Touro College of Osteopathic Medicine (NY/MT)

Touro lists CASPer results as part of its secondary application and says it weighs personal attributes in equal measure with academic metrics and experiences (Touro admission requirements). For fall 2027 admission it says CASPer must be taken between March 19, 2026 and February 9, 2027, that earlier results are not valid, and that CASPer fees are separate from Touro's application fee. Acuity accepts your AACOMAS ID or a Touro ID.

University of Northern Colorado COM

UNC COM says all applicants are required to complete Casper, and that if you have already taken it you can add UNC COM to your distribution list in your Acuity account (UNC COM requirements). Its page also lists a minimum MCAT of 498 with no section below 123 and a minimum overall GPA of 3.0. Its Acuity distribution deadline is February 22, 2027.

William Carey University COM (Mississippi)

William Carey says a CASPer score is required as part of the secondary application and must come from a test taken in the current cycle (WCUCOM admissions). Its AACOMAS deadline is March 15 and its secondary materials deadline is April 15, but Acuity's last accepted sitting is February 9, so do not wait for the school's later deadlines to book.

Why other lists show many more DO schools

Many published lists still name a dozen or more DO schools. When we checked Acuity's 2026–27 tool on November 14, 2026, only these four osteopathic programs were listed. A longer list can be wrong for several reasons:

• It was written for an earlier cycle and not rechecked after schools changed their requirements.
• It mixes DO and MD programs, or includes programs that recommend rather than require the test.
• It was copied from another site rather than checked against Acuity or the school.

The reliable check takes two minutes: open Acuity's Dates and Fees page, choose United States, the current cycle and Osteopathic Medicine, then confirm on the school's own admissions page. Our broader medical schools that require CASPer guide and schools that don't require CASPer cover MD and Canadian programs.

One CASPer test covers DO and MD schools

Acuity lists Osteopathic Medicine and Allopathic Medicine under the same US test, Medicine (CSP-10111). If you apply to both, take CASPer once and add every school to your distribution list. The fee is $85 USD including nine schools, plus $20 USD per additional school, and it is non-refundable and valid for this cycle only. You cannot take the same test type twice in one cycle, so a single sitting has to serve your whole list.

The test is the standard 2026–27 format: four video-response scenarios with one minute per answer, then seven typed scenarios with 3.5 minutes per pair, about 65 to 85 minutes in total (Acuity format article). Sam Houston's page still describes a 90–110 minute test, which reflects an earlier format. No osteopathic or clinical knowledge is tested.

Booking and preparing

1. Pick your sitting from your earliest deadline. Sam Houston applicants: December 3. Touro, Northern Colorado and William Carey applicants: any of the three remaining dates.
2. Book under United States, Medicine (CSP-10111), add every DO and MD school with the ID it asks for, and keep your name and email identical to your applications.
3. Rehearse the format. Take Acuity's free official practice test, practise one-minute video answers and complete a timed practice test.

Results: Acuity usually notifies applicants of their quartile about four to five weeks after the test, while schools receive scores through your distribution list. See how CASPer is scored.

Sources and scope

Checked November 14, 2026 against Acuity's Dates and Fees tool (United States, Osteopathic Medicine, 2026–27) and the admissions pages of Sam Houston State, Touro, Northern Colorado and William Carey. Requirements change between cycles; each school's page and Acuity's tool are the final word. CasperCoach is independent of these schools and Acuity Insights.
