ExploreAbout this exam
The American Board of Neurological Surgery (ABNS) certification is the specialty board credential for neurosurgeons who have completed accredited residency training and want to demonstrate that they meet the profession's standard for independent practice. Candidates typically pursue it after residency, often alongside or after the oral examination sequence, and maintain it through continuing certification. The written examination samples the full breadth of neurosurgery rather than a single subspecialty: trauma and critical care, cerebrovascular disease, tumors, spine and peripheral nerve, pediatrics, functional and stereotactic work, epilepsy, hydrocephalus and CSF disorders, skull base and cranial nerve problems, neurocritical care and neuroanesthesia, imaging and diagnostics, and basic and clinical neuroscience. Expect clinically framed, case-based multiple-choice items that test judgment and management as much as recall, with imaging described in text rather than shown. Preparation is best built as a structured review over several months: work domain by domain from a current general textbook, read around each topic rather than memorizing isolated facts, and use question practice to find gaps and rehearse decision-making under time pressure. This page is an independent study resource and is not affiliated with or endorsed by the ABNS; candidates should confirm eligibility, format, scheduling, and current requirements directly with the Board.
What you'll study
About ABNS Neurological Surgery preparation
Who is eligible to sit for ABNS certification?
Eligibility is set by the Board and generally involves completion of an accredited neurosurgical residency plus other requirements the Board specifies. Because criteria and documentation change, check the ABNS website for the current eligibility rules rather than relying on a summary.
What is the exam format?
The qualifying component is a computer-based, multiple-choice examination covering the breadth of neurosurgery. The Board also administers a separate oral examination. Confirm the current structure, item format, and any changes on the ABNS site before you build a study plan around it.
How long is the exam and how many questions does it have?
The Board publishes the current question count, time limit, and scheduling details; those figures are not fixed permanently and should be taken from the official source. Plan your pacing practice around the published numbers once you have them.
What score do I need to pass, and what does it cost?
Passing standards and fees are set and published by the ABNS and can change between administrations. This page deliberately does not quote them. Consult the Board's website for the current passing score policy and fee schedule.
How difficult is the exam?
It is a broad, high-stakes specialty exam taken after years of residency, so most candidates find the difficulty comes from breadth rather than obscurity. Items reward safe, evidence-consistent management. The candidates who struggle are usually those who studied only their own subspecialty.
Can I retake it if I fail?
Retake policies, waiting periods, and any limits on attempts are determined by the Board. Look up the current policy on the ABNS website before you assume a timeline, and build in margin so a single poor performance does not disrupt your career plans.
In what order should I study the domains?
Start with your weakest high-yield areas rather than your comfort zone. Spine, trauma, and neuro-oncology carry substantial weight and reward systematic review; layer in vascular, pediatric, and functional topics next. Finish with rapid review and timed mixed-topic practice so you rehearse switching between domains.
What are the most common failure modes?
Studying only one subspecialty, memorizing facts without management context, neglecting imaging interpretation described in text, and running out of time on long vignettes. Practicing mixed-topic questions under timed conditions exposes all four before exam day.
How far in advance should I start preparing?
Most candidates benefit from a structured plan of several months alongside clinical duties, with the final weeks reserved for timed practice and weak-area review. Adjust to your own baseline; the Board does not prescribe a preparation timeline.
Does this page reflect official ABNS content?
No. This is an independent study resource and is not affiliated with, endorsed by, or connected to the ABNS. Domain names and weights shown here are an unverified structural draft. Always treat the Board's own publications as authoritative for content, format, and policy.
