- DABCRS status requires passing ABCRS Part I, a six-hour multiple-choice exam, plus a separate oral Part II - this guide covers Part I prep only.
- The March 2024 Instructions for Question Writers lists six content categories shared across ABCRS exams, with no official percentage weighting published.
- The next written exam is scheduled for March 10, 2027; the application window for that cycle closed September 10, 2026.
- 2027-cycle costs are a $400 application fee plus a separate $1,200 Part I exam fee, with late penalties if you miss posted deadlines.
What DABCRS Actually Tests
Before opening a single question bank, get clear on what you're actually studying for. The credential path this guide addresses is Diplomate of the American Board of Colon and Rectal Surgery, awarded by the American Board of Colon and Rectal Surgery (ABCRS). The specific hurdle covered here is the ABCRS Part I Written Examination - a six-hour, multiple-choice test of the theory and practice of colon and rectal surgery, including relevant radiology, pathology, and basic science. Passing Part I is necessary but not sufficient for Diplomate status: Part II is a separate oral examination, and continuing certification (including CertLink reporting) is a distinct, later obligation.
If you're still mapping out what the letters after a colleague's name signify, our companion pieces on What Is DABCRS?, DABCRS Meaning, and What Does DABCRS Stand For? walk through the terminology before you get into exam mechanics. This article assumes you already know you're sitting Part I and want a concrete plan for the content, format, and logistics.
Exam Format and Test-Day Mechanics
Part I is delivered as computer-based testing at Pearson VUE test centers, with scheduling coordinated through the American Board of Surgery (ABS). You cannot simply register on Pearson VUE's site - booking requires an approved ABCRS application, payment of the exam fee, and an Examination Admission Authorization letter. Use the Candidate ID from that letter when you schedule your seat.
On test day, bring the authorization letter itself plus two forms of ID whose names match the letter exactly. One ID must carry a photograph; both must carry signatures. Pearson VUE's ABCRS-specific page notes that testing centers in Quebec, Canada are excluded from the network, so Canadian candidates should confirm their nearest eligible location well in advance.
The exam is scheduled for six hours. That figure describes the length of the testing appointment, not a promise of six uninterrupted hours of question-answering - build in mental stamina training accordingly, not just content review.
Key Takeaway
Confirm your Candidate ID and authorization letter details match your government ID exactly weeks before test day - mismatches are an easily avoidable reason to be turned away at check-in.
The Six Content Areas You Must Master
ABCRS's question-writing manual organizes item content into six categories that candidates should treat as their content map, even without official weighting. For a deeper breakdown of each area, see our full DABCRS Exam Domains 2026: Complete Guide to All 6 Content Areas. Here's the high-level view:
Domain 1: Perioperative Considerations and Colonoscopy
This is a broad operational category spanning the entire patient journey around surgery and endoscopy.
- Antibiotic and DVT prophylaxis, bowel preparation, and fluid/electrolyte management
- Postoperative recovery pathways and ileus prevention
- Recognition and management of intraoperative complications
- Colonoscopy preparation, polyp screening and marking, polypectomy technique, and procedural complications
Domain 2: Anorectal
Classic bread-and-butter colorectal pathology that shows up heavily in daily practice and, by extension, on the exam.
- Hemorrhoid mechanisms, grading, and both office-based and surgical management
- Anal fissure diagnosis and step-up treatment options
- Special patient circumstances (e.g., pregnancy, immunosuppression, prior anorectal surgery)
- Recognizing and managing treatment complications
Domain 3: Pelvic Floor, Fecal Incontinence, Lower GI Motility/Constipation
Functional colorectal disorders that require integrating physiology with surgical and non-surgical treatment ladders.
- Pelvic floor dysfunction workup and imaging correlation
- Fecal incontinence grading and staged treatment pathways
- Slow-transit constipation vs. outlet obstruction differentiation
Domain 4: Benign Disease and IBD
Covers inflammatory and non-malignant structural disease across the colon and rectum.
- Diverticular disease staging and surgical decision points
- Crohn's disease and ulcerative colitis: medical-surgical interface and complication management
- Benign strictures, fistulas, and other structural pathology
Domain 5: Neoplasia
Oncologic knowledge across staging, operative planning, and multidisciplinary management.
- Colorectal cancer staging systems and their treatment implications
- Operative approach selection for various tumor locations and stages
- Adjuvant/neoadjuvant therapy interplay with surgical timing
Domain 6: Miscellaneous
A catch-all category for topics that don't fit neatly elsewhere but still appear in practice and on the exam - treat it as a reminder not to over-narrow your review to the five "named" domains.
Because ABCRS does not publish an official weighting scheme, resist the urge to hunt for a leaked percentage breakdown. Instead, build your own confidence map by working through original practice questions tagged to each of these six areas and tracking where you're weakest.
Registration, Fees, and the 2027 Deadlines
Getting to test day involves a two-part payment structure and a strict application calendar. For the 2027 cycle:
- Application fee: $400, with application materials and the ACGME operative log due August 15, 2026 (late applications were accepted through September 10, 2026, at an additional $200 charge). As of this review date, that application window is closed.
- Part I examination fee: $1,200, separate from the application fee, due January 15, 2027. Late payment is accepted January 16-19, 2027, but totals $1,400 (including the $200 late charge) - no payment is accepted after January 19.
The board's dates page lists the next written examination as March 10, 2027. Note that the written-exam landing page itself still shows a historical March 3, 2026 date in places - treat the Important Dates page and the 2027 candidate timeline as the reconciling sources, and recheck ABCRS's current instructions before submitting any payment, since fee and date pages are updated independently.
For the full cost breakdown alongside continuing-certification fees, see DABCRS Certification Cost 2026: Complete Pricing Breakdown. If you haven't confirmed you meet the residency, licensure, and operative-log prerequisites yet, start with DABCRS Requirements 2026: Eligibility, Prerequisites & How to Qualify before you spend a dollar on fees.
| Item | Amount / Date (2027 cycle) |
|---|---|
| Application fee | $400 (due Aug 15, 2026; late window closed Sept 10, 2026) |
| Late application surcharge | +$200 |
| Part I examination fee | $1,200 (due Jan 15, 2027) |
| Late exam-fee total | $1,400 (Jan 16-19, 2027 window; no payments after Jan 19) |
| Next written exam date | March 10, 2027 |
A Domain-by-Domain Study Timeline
General study methodology only matters if it's mapped to what's actually on Part I. Rather than a generic weekly template, sequence your review around the six categories, saving integrative practice-question sessions for the final stretch before your Pearson VUE appointment.
Perioperative Considerations and Colonoscopy
- Drill bowel prep protocols, prophylaxis regimens, and postoperative complication recognition
- Work colonoscopy-specific items: screening intervals, polypectomy technique, procedural complications
Anorectal + Pelvic Floor/Incontinence/Motility
- Pair these two domains since they share anatomy and often overlapping physical exam findings
- Focus extra time on fissure and hemorrhoid management ladders, plus incontinence grading systems
Benign Disease/IBD + Neoplasia
- Contrast medical vs. surgical decision points in IBD with oncologic staging-driven decisions in neoplasia
- Build a personal reference sheet of staging systems and their operative implications
Miscellaneous + Full Mixed Practice
- Review remaining miscellaneous topics you've flagged as gaps in prior weeks
- Shift to timed, mixed-domain practice blocks that mimic the six-hour appointment length
Use an error log throughout - every missed practice question should be tagged to one of the six domains so you can see, objectively, whether your Domain 3 or Domain 5 knowledge is actually the weak point, rather than guessing. If you want a single-page reference to sanity-check your recall in the final week, our DABCRS Cheat Sheet 2026: One-Page Review of Must-Know Facts is built for that last-mile review, not first-pass learning.
Practice Questions vs. Course Materials
There isn't one single "official" ABCRS question bank you buy and finish - your preparation will likely combine a few resource types. It's worth being clear-eyed about what each one actually offers:
- Original, source-dated practice questions - like the ones on our practice test platform - built around the six category names above, with distractor rationales so you understand why a wrong answer is wrong, not just that it's wrong.
- Reference textbooks, such as the ASCRS Textbook of Colon and Rectal Surgery, useful for deep-diving a topic once a practice question exposes a gap, but not efficient as a first-pass study format on their own.
- Broader educational programs that offer practice quizzes with critiques as part of a larger curriculum - these can be useful supplements, but their internal topic pillars are course-defined, not the ABCRS classification used on this site.
- Review courses aimed at qualifying/continuing-certification prep, which are sometimes bundled separately from oral-exam-specific products - check carefully whether a given course is built for Part I's written format or for oral-boards-style preparation, since the two require different practice formats entirely.
Whatever mix you use, be skeptical of any resource that claims to hand you "actual" or "recalled" exam questions - no legitimate prep vendor has access to ABCRS's live item bank, and claims to the contrary should be a red flag rather than a selling point. Practice-question performance is diagnostic feedback on your knowledge gaps, not a validated prediction of your real pass probability.
Once you've compared formats, start building actual repetitions on the main practice test site and track your domain-by-domain accuracy rather than a single aggregate score.
Mistakes That Sink First-Time Candidates
- Treating all six domains as equally weighted by default. With no official percentage breakdown published, don't assume even distribution - use your own practice-question performance to allocate more review time to your weaker categories.
- Missing the two-payment structure. Candidates sometimes assume the application fee covers the exam itself; it doesn't. The $1,200 Part I fee is separate and has its own January deadline with its own late-payment cutoff.
- Confusing Part I prep with Part II prep. Part I is multiple-choice; Part II is oral. Studying case-presentation style for a written multiple-choice exam wastes preparation time. If you're unsure how the two compare in difficulty and format, see How Hard Is the DABCRS Exam? Complete Difficulty Guide 2026.
- Ignoring ID and authorization-letter details until the last minute. Name mismatches between your Candidate ID letter and your photo IDs are an entirely preventable reason to be denied entry at a Pearson VUE center.
- Assuming a single passing threshold number is public knowledge. If you're trying to understand how performance is actually scored, read DABCRS Passing Score 2026: Exactly What You Need to Pass rather than relying on rumor.
It's also worth stepping back periodically and asking whether the credential fits your career plans - see Is the DABCRS Certification Worth It? Complete ROI Analysis 2026 and DABCRS Jobs for context on how the certification is used by employers and credentialing committees once you've passed both parts.
FAQ
No. Part I is a written multiple-choice exam and is one step in the pathway. Part II is a separate oral examination, and Diplomate status requires passing both, on top of meeting ABCRS's residency, licensure, and application requirements.
Perioperative Considerations and Colonoscopy, Anorectal, Pelvic Floor/Fecal Incontinence/Lower GI Motility/Constipation, Benign Disease and IBD, Neoplasia, and Miscellaneous - categories drawn from ABCRS's own question-writer instructions, without official percentage weighting.
A $400 application fee and a separate $1,200 Part I examination fee, per ABCRS's published fee schedule. Late applications add $200; late exam-fee payment brings the total to $1,400, with no payments accepted past January 19, 2027.
Computer-based testing at Pearson VUE test centers (excluding Quebec, Canada), coordinated through the American Board of Surgery. You need an approved application, paid exam fee, and Examination Admission Authorization letter to schedule your seat.
As of this review, the application window for the 2027 cycle (materials due August 15, 2026, late window through September 10, 2026) has closed. Check ABCRS's Important Dates page directly for the next open cycle before planning your timeline.
