ExploreAbout this exam
The ABPN Neurology and Developmental Disorders (NDD) subspecialty certification is a credential offered by the American Board of Psychiatry and Neurology, a member board of the American Board of Medical Specialties. It is designed for physicians who have completed qualifying neurology training and wish to demonstrate subspecialty expertise in the neurologic care of individuals with developmental disorders across the lifespan. The examination is computer-based and administered through Pearson testing centers, and candidates apply through the ABPN physician portal. Content spans general neurology and neuroscience foundations, normal and abnormal nervous system development, diagnostic and clinical assessment of neurodevelopmental disorders, and treatment, management, and systems of care. Once certified, diplomates maintain the credential through ABPN Continuing Certification, which includes self-assessment, improvement in medical practice, patient safety activities, and article-based requirements. Preparation should be structured around the four content domains rather than rote memorization, with emphasis on developmental trajectories, syndrome recognition, and multidisciplinary management. Candidates should consult the ABPN website directly for current exam dates, fees, deadlines, and application requirements, as these details are updated periodically and are not reproduced here.

What you'll study
About ABPN NDD preparation
Who is eligible to sit for the NDD subspecialty exam?
Eligibility is set by the ABPN and generally requires completion of accredited neurology training plus any additional requirements specific to the subspecialty. Because eligibility rules and accepted training pathways change, verify your individual qualifications through the ABPN physician portal and the official subspecialty certification page before applying.
What is the exam format?
The ABPN delivers its certification examinations by computer at Pearson testing centers. The NDD exam is a multiple-choice, single-best-answer examination organized around the subspecialty content domains. Confirm the current appointment length, item count, and any breaks through the ABPN exam schedule and candidate materials rather than relying on secondhand descriptions.
How long is the exam and how many questions does it have?
Those figures are published by the ABPN and are not reproduced here because they are revised periodically. Check the ABPN exam schedule and your candidate admission materials for the authoritative timing and item count for your specific appointment. Plan your pacing practice around the official numbers once you have them.
What score do I need to pass?
The ABPN sets the passing standard for each examination and does not publish a simple percentage threshold that applies across all administrations. Scoring is criterion-referenced against the established standard. Review the ABPN candidate materials for how results are reported, and treat any specific percentage you encounter online as unofficial.
What happens if I fail - can I retake it?
The ABPN permits re-examination under its published policies, which specify application windows, waiting periods, and any limits on attempts. These rules are updated periodically, so confirm the current retake policy directly with the ABPN before planning a second attempt, and build extra study time into your timeline.
How long is the certification valid?
ABPN certificates are time-limited and maintained through Continuing Certification rather than issued for life. Diplomates meet ongoing requirements including self-assessment, improvement in medical practice, patient safety activities, and article-based assessments. Confirm your specific certificate's expiration date and requirements through the ABPN physician portal.
In what order should I study the four domains?
Start with neuroscience and development foundations, since syndrome recognition and treatment decisions depend on them. Then move to clinical assessment, where developmental history, examination findings, and diagnostic criteria are tested together. Finish with treatment and systems of care, which rewards integration. Reserve the final weeks for mixed practice that forces you to switch domains within a single session.
What are the most common failure modes?
Candidates most often lose points by memorizing syndrome names without knowing developmental trajectories, by underweighting normal variation and milestone timing, and by neglecting systems-of-care and multidisciplinary management content. Weak performance on foundational neuroanatomy and genetics also costs easy points. Practicing applied, case-style reasoning rather than isolated fact recall addresses most of these gaps.
How much lead time do I need before the exam?
Most candidates benefit from three to six months of structured preparation alongside clinical duties, with the first half spent on foundations and the second on applied question practice and review of missed items. Adjust for how recently you completed developmental neurology rotations. Confirm your application deadline early, since deadlines precede exam dates.
Does this page or its practice material count as official ABPN guidance?
No. This is an independent study resource and is not affiliated with, endorsed by, or sponsored by the ABPN.
