- The DACNB is issued by the American Chiropractic Neurology Board and is not the AFMA/AANOS credential or physician board certification.
- The written blueprint has sixteen domains; Cerebellar/Vestibular is the heaviest at 10%, followed by Brainstem and Autonomic at 8% each.
- Diagnosis, differential diagnosis and disease processes account for 42% of written work activities, so localization reasoning outranks recall.
- The performance exam is a separate hands-on test: cranial nerve exams (18%) and cerebellar/vestibular evaluation (17%) lead its scope.
What You Are Actually Preparing For
The Diplomate of the American Chiropractic Neurology Board (DACNB) is the credential awarded by the American Chiropractic Neurology Board (ACNB) in the field of chiropractic neurology. Before you build a study plan, be clear about what the credential is and is not. It is not the AFMA/AANOS Clinical Neurology certification, it is not a chiropractic sports-physician credential, and it does not establish equivalence to physician neurology board certification such as ABPN. Candidates and employers should treat it as its own discipline-specific diplomate designation. If you want a broader orientation first, What Is DACNB Certification? covers the basics, and DACNB Requirements 2026: Eligibility, Prerequisites & How to Qualify explains who can sit for it.
The examination process has two distinct halves that demand different preparation. There is a written examination, which is knowledge-based and organized around sixteen content domains, and a performance examination, which tests physical-examination skills and case-study reasoning. A study plan that treats the whole thing as one big reading assignment will leave a gap on one side or the other. This guide is built around that split. For a candid view of the challenge, see How Hard Is the DACNB Exam? Complete Difficulty Guide 2026.
The Sixteen-Domain Blueprint and Where the Points Sit
The weights below come from the 2024-final written-examination blueprint in the October 3, 2024 ACNB Job Analysis Report, which is consistent with the Candidate Handbook revised in August 2024. Use these figures, not older column weights or survey recommendations you may find in outdated study materials. The handbook sometimes uses equivalent labels (for example Cerebellum, Reflexogenic Systems and Neuro-Endocrine System), so do not be thrown if a source phrases a domain slightly differently.
| Domain | Weight | Study Posture |
|---|---|---|
| Cerebellar/Vestibular | 10% | Highest priority; schedule early and revisit often |
| Brainstem | 8% | High priority; pairs naturally with cranial nerves |
| Autonomic Nervous System | 8% | High priority; pathway and pharmacology-style reasoning |
| Peripheral Nerves | 7% | Core localization material |
| Cranial Nerves | 7% | Core localization; also drives the performance exam |
| Pain | 7% | Mechanisms and pathways; ties to head and face pain |
| Spinal Cord | 6% | Tract and lesion localization |
| Head and Face Pain | 6% | Differentiation of presentations |
| Basal Ganglia | 6% | Circuit logic and movement disorders |
| Lobes of the Brain | 6% | Cortical syndromes and localization |
| Neuron Theory | 5% | Foundational physiology |
| Receptor Systems | 5% | Foundational physiology |
| Reflexogenic System | 5% | Reflex arcs and integration |
| Limbic System | 5% | Circuitry and behavior correlates |
| Brain and Its Environment | 5% | Protective and supportive structures |
| Neuroendocrine System | 4% | Smallest weight; do not neglect, but do not over-invest |
Two cautions about reading this table. First, the percentages are rounded. The handbook's displayed per-domain item allocations do not exactly equal the rounded percentage multiplied by 300 for Brainstem and Pain, so do not try to back-calculate precise question counts per domain; treat the weights as directional guidance on emphasis. Second, a domain's weight is not a measure of its difficulty. Neuron Theory and Receptor Systems are low-weight but underpin almost every higher-level concept, so shaky foundations there will cost you points elsewhere.

The Work-Activity Axis: How Questions Are Framed
Beyond what subject a question touches, the blueprint also describes what the clinician is being asked to do. The written examination work activities, totaling 100%, are distributed as follows:
| Work Activity (Written Exam) | Weight |
|---|---|
| Identify Diagnosis(es), Differential Diagnosis(es), Disease Processes, Metabolic Rate, Pathways | 42% |
| Treatment and Rehabilitation | 24% |
| Perform a Physical Exam | 20% |
| Conduct or Order Special Studies | 6% |
| Take a Patient History | 5% |
| Referral | 3% |
The practical meaning is significant. Roughly two-thirds of the written exam, by this axis, sits in diagnostic reasoning and treatment or rehabilitation decisions. History-taking and referral are small slices. That should reshape how you study: do not just memorize that a structure exists and what it connects to. Practice working from a clinical presentation toward a localized lesion, a differential, the underlying disease process or pathway, and then a rationale for management. A candidate who can recite tract anatomy but cannot reason from a deficit pattern to a lesion site is preparing for a different exam.
What "Diagnosis, Pathways and Disease Processes" Rewards
This is the single largest slice of the written exam, so train for it deliberately.
- Work backward from findings: given a set of deficits, name the most likely lesion locus and justify it.
- Build differentials that explain why competing localizations are less likely.
- Connect each syndrome to its underlying pathway and disease process rather than memorizing isolated facts.
- Be ready to link a diagnosis to a rational treatment and rehabilitation approach, since that is the next-largest activity.
Preparing for the Performance Examination
The performance examination is where many candidates under-prepare, because it cannot be studied from a book alone. It has its own distributions. For the physical-examination component, the scope is distributed as follows:
| Physical-Examination Area | Weight |
|---|---|
| Perform Cranial Nerve Examinations | 18% |
| Evaluate the Cerebellum and Vestibular Systems | 17% |
| Perform Testing of the Motor Systems | 14% |
| Perform Sensory Examinations | 10% |
| Perform Tests Related to the Basal Ganglia | 10% |
| Evaluate Cardiovascular, Respiratory, and Abdomen | 9% |
| Perform Reflex Testing | 6% |
| Perform Cognitive Tests | 6% |
| Perform Tests Related to the Limbic System | 5% |
| Obtain the Patient's Vital Signs | 3% |
| Additional Tests | 2% |
Notice how closely this tracks the written heavyweights: cranial nerves and the cerebellar/vestibular system dominate both. That overlap is an efficiency opportunity. Time you spend mastering the cranial nerve examination, with its sequence, technique and interpretation, pays off on both halves of the exam.
The case-study portion of the performance exam has a separate distribution: Identify Diagnosis(es), Differential Diagnosis(es), Disease Processes, Metabolic Rate, Pathways 45%; Treatment and Rehabilitation 30%; Perform a Physical Exam 10%; Conduct or Order Special Studies 6%; Review a Patient History 5%; Referral 4%. Again, diagnostic reasoning and treatment planning make up the bulk.
Domain-by-Domain Priorities
Rather than a flat list, group the sixteen domains by how they fit together clinically. Studying related domains in clusters mirrors how real cases present and reduces the isolated-fact trap.
Cluster One: The Posterior Fossa and Brainstem Core
Cerebellar/Vestibular (10%), Brainstem (8%), Cranial Nerves (7%)
These three domains together represent a quarter of the written blueprint and also feed the two largest performance-exam examination areas. Treat them as a single integrated study block.
- Be able to localize a lesion from a combination of cranial nerve findings and long-tract signs.
- Know cerebellar syndromes and how vestibular findings distinguish central from peripheral patterns.
- Practice the cranial nerve examination as a motor skill, not just as a list.
Cluster Two: Peripheral to Central Pathways
Peripheral Nerves (7%), Spinal Cord (6%), Receptor Systems (5%), Reflexogenic System (5%)
This cluster is about signal entry, transmission and reflex integration, and it is heavy on localization logic.
- Distinguish root, plexus and peripheral nerve patterns from cord patterns.
- Know receptor types and how they relate to the modalities tested at the bedside.
- Connect reflex arcs to the reflex testing you will perform in the performance exam.
Cluster Three: Regulation, Movement and Higher Function
Autonomic (8%), Basal Ganglia (6%), Limbic (5%), Lobes of the Brain (6%), Neuroendocrine (4%)
These domains reward circuit-level thinking and an understanding of how systems modulate one another.
- Autonomic Nervous System carries the same weight as Brainstem, so do not treat it as an afterthought.
- Link basal ganglia circuitry to the movement findings you will test in the performance exam.
- Connect limbic and cortical lobe syndromes to the cognitive testing component.
Cluster Four: Pain and Its Neighbors
Pain (7%), Head and Face Pain (6%), Neuron Theory (5%), Brain and Its Environment (5%)
Pain mechanisms and head and face pain presentations overlap heavily; study them together. Neuron Theory and Brain and Its Environment supply the physiological and structural context beneath everything else.
- Know ascending and descending pain pathways and modulation concepts.
- Differentiate head and face pain presentations by their features and underlying mechanisms.
A Domain-Sequenced Study Plan
This is the one place for a time-based template, and it is deliberately tied to the blueprint rather than to generic method. Adjust the pacing to your own timeline and to the testing windows described in DACNB Exam Dates 2026: Testing Windows, Deadlines & Scheduling. The logic: build foundations first, hit the heaviest domains while you still have time to revisit them, and keep hands-on practice running in parallel from the start rather than saving it for the end.
Foundations and Pathways
- Neuron Theory and Receptor Systems for baseline physiology.
- Peripheral Nerves, Spinal Cord and Reflexogenic System for localization logic.
- Begin rehearsing the sensory, motor and reflex portions of the bedside exam.
The Heavy Core
- Brainstem, Cranial Nerves and Cerebellar/Vestibular as one integrated block.
- Daily practice of the cranial nerve exam and cerebellar/vestibular testing.
- Case-based localization drills working from deficits to lesion sites.
Regulation, Movement and Cortex
- Autonomic Nervous System, Basal Ganglia, Limbic System, Lobes of the Brain, Neuroendocrine System.
- Rehearse basal ganglia and cognitive testing aloud and in sequence.
Pain, Context and Integration
- Pain, Head and Face Pain, Brain and Its Environment.
- Mixed-domain case reviews emphasizing differential diagnosis and treatment rationale.
- Timed run-throughs of the full physical examination sequence.
Key Takeaway
Let the blueprint set your time budget. Give the Cerebellar/Vestibular, Brainstem, Cranial Nerve and Autonomic domains the most review cycles, and keep the bedside examination in rotation every week instead of cramming it at the end.

Using Practice Questions Without Over-Trusting Them
Practice questions are valuable for the written examination, particularly for pressure-testing your diagnostic reasoning across the sixteen domains. Use them diagnostically: after each set, tag every miss by domain and by work activity. If most of your misses cluster in diagnosis and differential questions, more passive reading will not fix it; you need more case-style localization practice. If misses cluster in a single domain, return to that cluster of the plan above. You can try domain-organized questions on the DACNB Exam Prep practice test site, and the full question bank and tools are available from the main practice hub.
A caution worth repeating: scoring well on multiple-choice sets is not evidence that you are ready for the performance examination. Knowledge practice and skills practice are separate tracks, and each needs its own time. Candidates who ignore the hands-on track because their question-bank scores look strong are taking an avoidable risk.
What You Must Verify Directly With ACNB
Some details that candidates naturally ask about could not be confirmed from the reviewed official sources, and this guide will not guess at them. The exam fee, the numeric passing score and the pass rate were not verified in the supplied sources, and the complete Competency Requirements Guide with its full leaf-level objectives was not retrieved here. The public job-analysis summary does not reproduce every underlying knowledge, skill and task statement either. Before you budget or plan around any of these, confirm them with ACNB directly through the ACNB resources page and the current Candidate Handbook. Our own pages on DACNB Certification Cost 2026, DACNB Passing Score 2026 and DACNB Pass Rate 2026 discuss what is and is not publicly documented.

Frequently Asked Questions
Cerebellar/Vestibular is the heaviest single domain at 10%. Brainstem and Autonomic Nervous System follow at 8% each, then Peripheral Nerves, Cranial Nerves and Pain at 7% each.
No. The work-activity axis crosses the sixteen content domains and describes what the clinician is asked to do, such as diagnose or treat. It is not six additional domains and should not be added to the domain weights.
No. Practice questions support knowledge preparation for the written exam, but they do not replace demonstrating clinical skills in the performance examination. You need dedicated, hands-on rehearsal of the bedside examination.
Within the physical-examination scope, cranial nerve examinations (18%) and evaluation of the cerebellum and vestibular systems (17%) are the largest areas, followed by motor system testing at 14%.
No. The DACNB is awarded by the American Chiropractic Neurology Board in chiropractic neurology and does not establish equivalence to physician neurology board certification such as ABPN. It is also distinct from the AFMA/AANOS Clinical Neurology certification.
Preparing well comes down to matching your effort to the blueprint: reason from findings to localization, cluster related domains, and keep your hands-on examination skills sharp alongside your reading.
