HM Exam Dates 2026: Testing Windows, Deadlines & Scheduling

Why Headache Medicine Certification Only Happens in Even Years

Most board exams run annually. Headache Medicine Certification, issued by the United Council for Neurologic Subspecialties (UCNS), does not. The initial examination is offered biennially, in even-numbered years. That single structural fact reshapes how you should think about exam dates: there is no "I'll just sit next fall" fallback. If you miss the 2026 cycle, your next opportunity is the 2028 examination week.

This guide is about the dates and logistics specifically. If you are still deciding whether the credential suits your practice, start with What Is HM Certification? and the broader ROI analysis. If you are already committed, the calendar below is the part that can quietly derail an otherwise strong candidate.

The 2026 Calendar: Deadlines, Extension and Exam Week

The 2026 cycle has four dates that matter. Everything else flows from them.

Notice that the application deadline and the exam week are separated by roughly six months. That gap is deliberate: UCNS reviews eligibility documentation, notifies candidates, and then opens scheduling. Candidates sometimes treat approval as the finish line and forget that approval does not book the appointment. Scheduling is a separate step with its own closing date, and in 2026 that date was October 5.

Application deadline versus scheduling deadline

These two deadlines fail in different ways. Missing the application deadline means you either pay the extended-application surcharge (if you land between April 15 and May 1) or lose the cycle entirely. Missing the scheduling deadline means you were approved and paid but may have no seat. For 2028, build both dates into your calendar the moment UCNS publishes them, and set a reminder well ahead of each one.

Testing Center or Remote: Choosing Where You Sit

UCNS delivers the exam through Meazure Learning, with two modes: in-person testing centers, or ProctorU online live proctoring. The current Headache Medicine certification page explicitly offers the testing-center option, which supersedes older UCNS process documents that described virtual-only administration.

Because the initial exam is closed book, neither mode lets you reference outside material. The practical difference is logistics risk. A remote candidate who skips the system check is introducing a failure point that has nothing to do with clinical knowledge. UCNS does not publish a general permission for a personal calculator, so do not assume you can bring one; rely on what the exam-day instructions for your chosen mode actually allow.

How Eligibility Pathways Interact With Dates

Eligibility is not just a yes/no gate; several pathways carry their own date rules that collide with the exam calendar. The full criteria live in the issuer's eligibility document (see our HM requirements guide for the complete breakdown), but the date-sensitive pieces are worth flagging here.

Fellowship pathway timing

Candidates who completed a UCNS-accredited Headache Medicine fellowship of at least 12 months must apply within 48 months of completion, with verification. Fellows who apply before finishing training face a specific constraint: they must complete the fellowship at least 25 days before exam week and submit program-director confirmation within 20 days after completion. For a 2026-style October 19 start, that means the training end date has to land comfortably before late September. A fellowship ending in mid-October does not qualify for that cycle, which is a common planning error for trainees on non-standard academic calendars.

Practice-track timing

The practice track requires 36 months with at least 25% Headache Medicine practice in the specified preceding 60-month window, two physician letters, and one qualifying training or education element (12 months of qualifying unaccredited HM training after neurology residency, 50 HM-specific Category 1 CME hours, or qualifying full-time academic teaching). Since the exam occurs only every two years, a candidate who is a few months short of the practice requirement can find that the shortfall costs a full two-year wait. If you are close, count your months precisely against the issuer's template before the application deadline.

Fees and the Cost of Missing a Deadline

Dates and dollars are linked because the extended-application window carries a surcharge. The published standard initial fee is $1,700, made up of a nonrefundable $680 application fee and a $1,020 examination fee. Eligible applicants from UCNS-accredited fellowship programs receive a $250 discount, which brings the figure to $1,450 before any additional fees. An extended application adds $500. Reexamination carries the $1,020 examination fee.

The practical date-related takeaway: filing by April 15 avoids the $500 extension surcharge, and the application fee is nonrefundable, so a candidate who applies and then cannot sit the exam should not expect that portion back. No member versus nonmember fee distinction is published.

What Exam Week Actually Looks Like

The initial examination is 200 multiple-choice questions in four hours. UCNS does not publicly specify a fixed scored versus unscored split, and items may be excluded from scoring after psychometric review, so do not plan around an assumed pretest count. No adaptive-testing specification was verified, so prepare for a standard linear sitting.

Two parts, one break

The exam is delivered in two parts with one break of up to 15 minutes after you submit the first half. The key behavior: once you submit the first half, you cannot return to those questions. That changes pacing strategy. You cannot bank hard questions to revisit at the end of the full exam; any flagging and review must happen before you submit the first half. Practice with this constraint in mind, using timed blocks that mirror a half-exam rather than one continuous marathon.

What the questions test

The content tracks the Headache Medicine Written Examination Content Outline (revised May 22, 2020, still linked from the 2026 certification page). Its five domains and official weights are:

Our domain-by-domain guide walks through each area. The outline describes examination objectives rather than a prep curriculum, and no subtopic weights are published, so be cautious of any resource claiming precise per-topic percentages. For the classification domain, the detailed outline additionally specifies ICHD-3, so fluency with the diagnostic criteria matters.

Retake Windows and the Six-Year Clock

The biennial schedule makes retake planning unusual. Initial-exam retakes are limited to two additional attempts within six years, with updated application information and the reexamination fee ($1,020). Since the exam is offered only in even years, six years spans three exam cycles: for example, a first attempt in 2026 leaves 2028 and 2030 as the retake opportunities, and the 2032 cycle would fall at or beyond the edge of that window.

UCNS uses criterion-referenced standard setting, and a public numeric initial-exam cut score has not been verified; see our passing score explainer for what is and is not known.

Working Backward From Exam Week: A Domain-Based Plan

Rather than a generic weekly template, schedule by domain weight and by what each domain demands. The only methodology note here: because you cannot revisit first-half questions, spend your final weeks on half-length timed blocks. Our full approach is in the HM study guide.

To pressure-test timing and the two-half structure, work through realistic questions on the HM practice test platform and review results by domain so your last weeks go where your weakest percentage-weighted areas are.

After Exam Week: Certification Continuity Begins the Next Year

Passing is not the end of the date calendar. Certification continues as long as annual continuous-certification (C-cert) requirements are met, starting the year after initial certification. The former ten-year recertification cycle has been discontinued. Each year you maintain medical licensure and primary board certification, complete the annual reading list, pay the annual fee of $175 per subspecialty ($150 if paid by June 1), and finish requirements by December 31.

The annual C-cert quiz is a separate instrument from the initial exam: 25 multiple-choice knowledge questions, a 100-minute session, access to designated reference articles, an 80% passing score and up to three attempts. Those specifications do not apply to the initial exam. Two consecutive years of unmet requirements lead to loss of certification, so the December 31 date is the recurring deadline that replaces the old exam-cycle pressure. For career context after certification, see HM salary guide and HM jobs, which avoid attributing an isolated salary premium to the credential alone.
