AD Exam Dates 2026: Testing Windows, Deadlines & Scheduling

The 2026 AD Exam Window at a Glance

The Autonomic Disorders Certification (AD) exam, administered by the United Council for Neurologic Subspecialties (UCNS), does not run every year. Because AD is offered only in even-numbered years, 2026 is a testing year - and the testing window is short and fixed: December 7-11, 2026. If you miss this window, the next opportunity will not arrive until 2028, so understanding the mechanics of registration, scheduling, and eligibility now matters more than it would for an annually offered exam.

This narrow cadence changes how candidates should plan. Unlike credentials with rolling testing dates, AD candidates need to work backward from a single five-day window and a hard application cutoff. If you're still confirming whether you even qualify to sit for the exam, review the full breakdown in AD Requirements 2026: Eligibility, Prerequisites & How to Qualify before locking in a study schedule.

Application Deadlines: Standard and Extended

UCNS set two application checkpoints for the 2026 cycle:

• Standard application deadline: June 15
• Extended application deadline: July 1 (adds $500 to the standard fee)

These dates have already passed for the December 2026 window, which means anyone reading this ahead of the 2028 cycle should treat June 15 and July 1 as the template for future planning. The extended deadline exists as a buffer for candidates who need a few extra weeks to gather documentation - verification letters, fellowship confirmation, or licensure records - but it comes at a real cost. Candidates who plan their eligibility documentation early, using the pathway breakdown in AD Requirements 2026, typically avoid paying the extended-application premium entirely.

Scheduling Your Test Date

Being approved to sit for AD is not the same as having a confirmed seat. Once UCNS approves an application, candidates enter a scheduling window - for 2026, that window runs July 20 through November 23 - during which they coordinate an actual test date within the December 7-11 exam period. Meazure Learning manages testing-center delivery and also supports live virtual proctoring through ProctorU with Guardian, giving candidates a choice between an in-person test center and remote testing from a private, compliant space.

Because the scheduling window closes nearly two weeks before the exam itself begins, candidates should not wait until late November to lock in a slot. Popular test-center locations and preferred virtual time blocks can fill before the scheduling window closes, especially since all candidates for the 2026 cycle are funneling into the same five-day period.

How the AD Exam Is Structured

The initial AD exam consists of 200 multiple-choice questions with a four-hour time limit, delivered closed-book. There is one break of up to 15 minutes between the two halves of the exam, and candidates cannot return to earlier questions once they've moved forward - a format detail that changes pacing strategy compared with exams that allow free navigation. Candidates testing virtually have access to an online calculator during the session.

Content is distributed evenly across four domains, each worth 25% of the exam:

Because all four domains carry equal weight, there is no shortcut of over-indexing on one area. For a deeper breakdown of what each domain actually tests and how questions are typically framed, see AD Exam Domains 2026: Complete Guide to All 4 Content Areas. If you're wondering how the exam's difficulty compares to what you're used to from fellowship or boards, How Hard Is the AD Exam? Complete Difficulty Guide 2026 walks through the format and cognitive demands in more depth.

Fees Tied to the 2026 Cycle

Registration fees are directly tied to the deadlines above, so timing your application affects your total cost:

• Standard initial fee: $1,700 total - $680 nonrefundable application plus $1,020 examination fee
• Fellowship-eligible discount: $1,450 total for candidates from UCNS-accredited fellowships ($250 savings)
• Extended application: adds $500 to whichever base fee applies
• Reexamination: $1,020

These figures matter for budgeting well before the December testing window opens. For a full cost breakdown, including how the fellowship discount interacts with the extended-application surcharge, see AD Certification Cost 2026: Complete Pricing Breakdown.

Eligibility Pathways Before You Register

UCNS updated the eligibility criteria for AD on December 11, 2025, and every applicant must satisfy a qualifying primary board certification, active medical licensure, and one of the approved routes into the exam:

• Accredited fellowship route: at least 12 months of AD training, with application required within 48 months of completing the fellowship.
• Practice track: 36 months of practice with at least 25% AD-focused clinical time within the applicable 60-month window, two physician verification letters, plus an additional qualifying component - further training, 50 hours of AD-specific CME, or academic teaching.
• Academic-appointment or internationally trained faculty pathway: an alternative route for qualifying academic or internationally trained candidates.

Because the practice track requires verification letters and documented CME hours, candidates on that pathway should begin assembling paperwork well before the June application deadline. Fellowship-track candidates have a firmer clock: waiting past 48 months post-fellowship removes that pathway entirely. Full detail on each route lives in AD Requirements 2026: Eligibility, Prerequisites & How to Qualify.

Test Day Logistics

AD candidates choose between two delivery formats supported through Meazure Learning:

• Test center: in-person, proctored administration at a Meazure Learning-affiliated site.
• Live virtual proctoring: remote delivery through ProctorU with Guardian, requiring a private, compliant testing space and stable internet connection.

Both formats are closed-book with a single break of up to 15 minutes between the two halves of the 200-question exam, and neither allows returning to previously answered questions once you've advanced. Virtual candidates get an on-screen calculator; test-center candidates should confirm what, if anything, is provided on-site ahead of their appointment. Given the strict no-backtracking rule, pacing across four hours and 200 items (roughly 70 seconds per question on average) is a skill worth rehearsing under timed conditions before exam day, not discovering during it.

Building Your 2026 Prep Timeline

Because the exam window is fixed and infrequent, a structured runway from application to test day helps prevent last-minute scrambling. Below is a sample sequencing approach anchored to the four equally weighted AD domains - adjust the calendar dates to whichever even year you're targeting.

For a domain-by-domain study plan with more granular weekly detail, see AD Study Guide 2026: How to Pass on Your First Attempt. If you'd rather rehearse under realistic timed conditions before committing to a test date, working through practice questions on our practice test platform can help you calibrate pacing against the real four-hour, 200-question structure.

C-cert and What Comes After Passing

Passing the initial AD exam is not the end of the certification lifecycle. Continuous certification (C-cert) begins the year after initial certification and requires designated readings plus a 25-question, 100-minute open-reference quiz. Candidates must score at least 80%, with a maximum of three attempts allowed, and completion is due by December 31 each year. The annual C-cert fee is $175 per subspecialty, dropping to $150 if paid by June 1.

Building C-cert into your annual calendar from the start - rather than treating it as an afterthought - keeps your certification active without last-minute scrambling.
