- DACNB means Diplomate of the American Chiropractic Neurology Board, awarded through the American Chiropractic Neurology Board (ACNB).
- The written blueprint has sixteen content domains; Cerebellar/Vestibular is the heaviest at 10%, followed by Brainstem and Autonomic at 8% each.
- Identifying diagnoses and differentials carries 42% of the written work-activity axis, and treatment and rehabilitation carries 24%.
- The performance examination tests hands-on skills; cranial nerve (18%) and cerebellar/vestibular (17%) examinations carry the most weight.
What the DACNB Credential Actually Is
The DACNB is the Diplomate of the American Chiropractic Neurology Board, the post-doctoral credential in chiropractic neurology awarded by the American Chiropractic Neurology Board (ACNB). Because several unrelated credentials in healthcare and elsewhere abbreviate to similar letters, precision matters here. This page is only about the chiropractic neurology diplomate. It is not the AFMA/AANOS Clinical Neurology certification, and it is not a chiropractic sports-physician credential.
If you are still orienting yourself to the terminology, these companion pages cover the basics from different angles: What Is DACNB?, What Does DACNB Stand For?, and What Is DACNB Certification?. This article goes a step further and maps the certification the way the ACNB itself defines it: through a published job analysis and a candidate handbook.
The Written and Performance Examinations
The ACNB blueprint distinguishes two kinds of demonstration. The written examination tests knowledge across sixteen content domains. The performance examination tests clinical skill, split into a physical-examination component and a case-study component. Each has its own published distribution, and none of them should be confused with the others.
This matters for how you prepare. Multiple-choice practice supports the knowledge side of the credential, but it does not replace demonstrating clinical skills in the performance examination. A candidate who can recite the anatomy of the vestibulo-ocular reflex but cannot sequence a cranial nerve examination efficiently has prepared for only half of the credential. The same logic runs the other direction: strong bedside technique without the underlying neuroanatomy and pathway reasoning will not carry the written portion.
For a candid look at how demanding this combination is, see How Hard Is the DACNB Exam?, and for eligibility questions, DACNB Requirements.
The Sixteen Content Domains and Their Weights
The weights below come from the current public 2024-final written-examination blueprint in the October 3, 2024 ACNB Job Analysis Report, consistent with the Candidate Handbook revised August 2024. Use these figures rather than older blueprint columns or survey recommendations, which describe earlier or aspirational weightings.
| Domain | Content Area | Weight |
|---|---|---|
| 1 | Neuron Theory | 5% |
| 2 | Receptor Systems | 5% |
| 3 | Peripheral Nerves | 7% |
| 4 | Spinal Cord | 6% |
| 5 | Brainstem | 8% |
| 6 | Cranial Nerves | 7% |
| 7 | Head and Face Pain | 6% |
| 8 | Cerebellar/Vestibular | 10% |
| 9 | Basal Ganglia | 6% |
| 10 | Reflexogenic System | 5% |
| 11 | Autonomic Nervous System | 8% |
| 12 | Limbic System | 5% |
| 13 | Lobes of the Brain | 6% |
| 14 | Brain and Its Environment | 5% |
| 15 | Neuroendocrine System | 4% |
| 16 | Pain | 7% |
The sixteen weights sum to 100%. One labeling caution: the Candidate Handbook uses some equivalent labels, including "Cerebellum" for the cerebellar/vestibular area, "Reflexogenic Systems" for the reflexogenic domain, and "Neuro-Endocrine System" for the neuroendocrine domain. If you see those variants in handbook text, they refer to the same domains listed above.
A second caution concerns question counts. The handbook's displayed per-domain item allocations do not exactly equal the rounded percentage multiplied by the total item count for every domain (Brainstem and Pain are examples), so this article does not infer or recompute per-domain question numbers. Plan from the percentages, and treat any specific item count you see circulated informally with skepticism. For a deeper domain-by-domain walkthrough, see DACNB Exam Domains: Complete Guide to All 16 Content Areas.
Reading the Weights as a Structure
The domains cluster naturally into three groups, which is a useful way to organize your review:
- Foundations: Neuron Theory, Receptor Systems, Peripheral Nerves, Spinal Cord, and Reflexogenic System. These are the building blocks that later domains assume.
- Brainstem-to-cortex systems: Brainstem, Cranial Nerves, Cerebellar/Vestibular, Basal Ganglia, Limbic System, Lobes of the Brain, and Brain and Its Environment.
- Regulatory and symptom-oriented domains: Autonomic Nervous System, Neuroendocrine System, Head and Face Pain, and Pain.
The Work-Activity Axis: Why Diagnosis Dominates
Separate from the content domains, the written examination is also described along a work-activity axis. This axis crosses the domains; it is not six additional content domains, and adding it to the domain weights would produce a meaningless 200% blueprint. Think of it as a second lens: each question touches a body-system domain and also reflects a type of clinical task.
| Written-Exam Work Activity | Weight |
|---|---|
| Take a Patient History | 5% |
| Perform a Physical Exam | 20% |
| Conduct or Order Special Studies | 6% |
| Identify Diagnosis(es), Differential Diagnosis(es), Disease Processes, Metabolic Rate, Pathways | 42% |
| Treatment and Rehabilitation | 24% |
| Referral | 3% |
The practical reading is straightforward. Roughly two out of every five written items are about reasoning toward a diagnosis, differential or pathway, and about a quarter concern treatment and rehabilitation. History-taking and referral together are a small slice. A candidate who studies each domain as a list of facts, without practicing lesion localization and differential reasoning, is studying against the grain of the blueprint.
Key Takeaway
For every domain you review, ask three questions in order: what does a lesion here look like clinically, what else could produce the same picture, and what would you do about it? That sequence mirrors the 42% diagnosis weight and the 24% treatment and rehabilitation weight better than memorizing anatomy in isolation.
What the Performance Examination Tests
The performance examination has its own published distributions, separate from the written blueprint. The physical-examination scope totals 100% on its own:
| Performance Exam: Physical Examination Scope | Weight |
|---|---|
| Obtain the Patient's Vital Signs | 3% |
| Perform Cranial Nerve Examinations | 18% |
| Perform Sensory Examinations | 10% |
| Perform Testing of the Motor Systems | 14% |
| Perform Reflex Testing | 6% |
| Evaluate the Cerebellum and Vestibular Systems | 17% |
| Evaluate Cardiovascular, Respiratory, and Abdomen | 9% |
| Perform Tests Related to the Basal Ganglia | 10% |
| Perform Tests Related to the Limbic System | 5% |
| Perform Cognitive Tests | 6% |
| Additional Tests | 2% |
The performance examination also includes a case-study component, again with its own distribution totaling 100%: 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%; and Referral 4%.
Two observations stand out. First, the physical-examination distribution is dominated by cranial nerve testing (18%) and cerebellar/vestibular evaluation (17%), followed by motor systems (14%). Second, the case-study distribution leans even harder on diagnosis (45%) and treatment and rehabilitation (30%) than the written exam does. Between them, those two activities account for three-quarters of the case-study weighting.
Skill Rehearsal Priorities for the Physical Exam
Because the physical-examination scope is a separate distribution, rehearse it as a bedside routine rather than as flashcard content.
- Run a complete cranial nerve sequence aloud until it is fluent, since it is the single largest physical-exam block at 18%.
- Practice cerebellar and vestibular testing as an integrated sequence, because that area is the second-largest block at 17%.
- Drill motor, sensory and reflex testing together so your findings can be tied to a localization.
- Do not neglect the smaller blocks (basal ganglia at 10%, cardiovascular/respiratory/abdomen at 9%, cognitive at 6%, limbic at 5%). They are small individually but add up.
Where the Weight Concentrates
Across both exams, the blueprint repeatedly points to the same neighborhood: the brainstem, cranial nerves and cerebellar/vestibular circuitry. On the written side, Cerebellar/Vestibular is the single largest domain at 10%, Brainstem and Autonomic Nervous System each carry 8%, and Peripheral Nerves, Cranial Nerves and Pain each carry 7%. On the performance side, cranial nerve and cerebellar/vestibular examinations together represent more than a third of the physical-exam scope.
Cerebellar/Vestibular (10%)
The heaviest written domain, and a heavy performance area as well. Candidates should be able to move fluently between circuit anatomy, examination findings and rehabilitation logic.
- Connect cerebellar and vestibular pathways to their clinical signs, so you can localize from a findings description.
- Practice distinguishing central from peripheral vestibular presentations.
- Link findings to treatment and rehabilitation choices, since that work activity carries 24% of the written exam and 30% of the case-study component.
Brainstem (8%) and Cranial Nerves (7%)
These two domains overlap heavily in practice, and the performance exam rewards integrating them.
- Know the cranial nerve nuclei and their brainstem relationships well enough to localize a lesion from a pattern of deficits.
- Be able to execute and interpret the full cranial nerve examination, not merely describe it.
- Review crossed and combined syndromes as localization puzzles rather than isolated facts.
Autonomic Nervous System (8%) and Neuroendocrine System (4%)
Easy to underweight because they feel less "bedside," yet the autonomic domain ties for second-largest on the written blueprint.
- Review autonomic pathways, receptors and their clinical consequences.
- Connect autonomic findings to the vital-signs and cardiovascular/respiratory/abdomen portions of the performance exam.
- Treat the smaller neuroendocrine domain as a compact, high-yield review rather than skipping it.
Pain (7%) and Head and Face Pain (6%)
Together these two domains account for 13% of the written blueprint, and they are tightly connected to diagnosis and treatment reasoning.
- Cover nociceptive pathways, modulation and the clinical syndromes built on them.
- Review head and face pain presentations as differential-diagnosis exercises.
- Pair each syndrome with a rationale for management, since treatment and rehabilitation is the second-largest work activity.

Fees, Passing Score and Pass Rate: What Is and Is Not Verified
Candidates reasonably want to know the exam fee, the numeric passing score and the pass rate. The honest answer is that none of those three figures was verified in the official materials reviewed for this article, which were the ACNB resources page, the Candidate Handbook revised August 2024, and the October 3, 2024 Job Analysis Report summary. The public job analysis summary describes what the credential tests; it is not a fee schedule or a scoring report.
The same caution applies to scheduling. Testing windows and deadlines are administrative details that change, so confirm them against current ACNB communications and see DACNB Exam Dates for how to approach that research.
Career Context and Scope Boundaries
The DACNB is a specialty credential for doctors of chiropractic who practice in chiropractic neurology. In practice, that usually means clinics built around functional neurology and neurorehabilitation, integrative or multidisciplinary practices that want a credentialed neurology-focused clinician, and private practice where the diplomate designation helps differentiate the practitioner. Because this article does not have verified earnings or hiring data, it makes no salary or job-market claims. For a qualitative look, see DACNB Jobs, DACNB Salary Guide and Is the DACNB Certification Worth It?.
The scope boundary bears repeating in professional communications. The credential should be described as a chiropractic neurology diplomate. It should not be presented as interchangeable with physician neurology board certification such as ABPN. Employers, referring clinicians and patients are best served by accurate descriptions of what the credential is.
Sequencing Your Preparation Around the Blueprint
A plan built on this blueprint should front-load foundations, give the brainstem-to-cerebellum cluster extended time, and keep the examination-skills rehearsal running in parallel rather than saving it for the end. The outline below is one reasonable ordering, not an official ACNB schedule, and you should stretch or compress it to fit your timeline.
Foundations
- Neuron Theory (5%) and Receptor Systems (5%).
- Peripheral Nerves (7%), Spinal Cord (6%) and Reflexogenic System (5%).
- Start rehearsing vital signs, sensory, motor and reflex testing as a fluent routine.
Brainstem, Cranial Nerves and Cerebellum
- Brainstem (8%), Cranial Nerves (7%) and Cerebellar/Vestibular (10%) together, since they share localization logic.
- Practice the full cranial nerve and cerebellar/vestibular exam sequences aloud.
- Do localization case drills that mix all three domains.
Higher Systems and Regulation
- Basal Ganglia (6%), Limbic System (5%), Lobes of the Brain (6%) and Brain and Its Environment (5%).
- Autonomic Nervous System (8%) and Neuroendocrine System (4%).
- Add cognitive testing and basal ganglia exam practice to your skills rotation.
Pain, Integration and Case Reasoning
- Pain (7%) and Head and Face Pain (6%).
- Mixed-domain diagnosis and differential drills, weighted toward the 42% diagnosis activity.
- Write out treatment and rehabilitation plans for cases, reflecting the 24% and 30% weights.
Interleave practice questions throughout rather than waiting until the end. Our DACNB practice tests are designed for knowledge-side preparation across the sixteen domains, and you can use targeted practice questions to find which domains need another pass. Remember that this supports the written examination and does not substitute for supervised practice of the performance examination skills.
Frequently Asked Questions
DACNB stands for Diplomate of the American Chiropractic Neurology Board, a credential in chiropractic neurology awarded through the American Chiropractic Neurology Board (ACNB). It is distinct from other credentials that may share similar letters, and it does not establish equivalence to physician neurology board certification such as ABPN. See DACNB Meaning for more.
There are sixteen content domains, from Neuron Theory through Pain, weighted according to the 2024-final blueprint. Cerebellar/Vestibular is the largest at 10%, and Neuroendocrine System is the smallest at 4%. The separate work-activity axis crosses these domains and is not an additional set of domains.
Yes. In addition to the written examination, there is a performance examination covering physical-examination skills and a case-study component. Cranial nerve examination (18%) and cerebellar/vestibular evaluation (17%) carry the largest physical-exam weights. Multiple-choice practice does not replace demonstrating these clinical skills.
These were not verified in the official materials reviewed for this article, so no figures are given here. Confirm current numbers directly with the ACNB, and see our pages on cost, passing score and pass rate for what is publicly documented.
Start with the weight concentration: Cerebellar/Vestibular (10%), Brainstem (8%) and Autonomic Nervous System (8%), with Cranial Nerves (7%) closely tied to the Brainstem. Pair that with diagnosis and differential reasoning, which carries 42% of the written work-activity axis, while rehearsing the cranial nerve and cerebellar/vestibular exam routines for the performance side. The DACNB Study Guide expands on this approach.
