NCBAHM (NCCAOM) 2026 Exam Changes: The New Content Outlines
If you sit any NCBAHM board exam on or after September 1, 2026, you are being tested on new content outlines. That covers all four modules: Foundations of Oriental Medicine, Acupuncture with Point Location, Biomedicine, and Chinese Herbology.
NCBAHM calls the reorganization of content domains the most notable change, and several modules shifted their percentage weights. Most of what you have studied still counts, but the mix is different. In Chinese Herbology, safety and quality control jumped from 10% of the exam to 24%. If your study plan still follows an outline from before September, it is pointing your hours at the wrong mix.
Here is what changed in each module, what didn't, and how to adjust, from a DACM who rebuilt a question bank around the new outlines.
The change at a glance

|---|---|---|
| Exams covered | January 1, 2020 to August 31, 2026 | On or after September 1, 2026 |
| Based on | The 2017 job analysis | The 2024 job analysis |
| Published by | NCCAOM | NCBAHM (the same board, renamed in January 2026) |
| Domains per module | ACPL 4, FOM 3, BIO 2, CH 3 | ACPL 4, FOM 3, BIO 4, CH 4 |
| Biggest weight shift | CH safety and quality control, 10% to 24% |
What changed in each module
NCBAHM doesn't publish a side-by-side comparison, so I lined up each 2026 domain with the closest 2020 domain. The weights come straight from the board's outlines; the pairings are my reading of what each domain covers.
Acupuncture with Point Location (ACPL)
| 2026 domain | 2026 weight | Closest 2020 domain | 2020 weight |
|---|---|---|---|
| I. Acupuncture Point Location | 15% | IV. Acupuncture Point Location | 15% |
| II. Safety for Acupuncture Practice | 15% | I. Safety and Professional Responsibilities | 15% |
| III. Treatment Planning | 40% | II. Treatment Plan | 50% |
| IV. Treatment Techniques | 30% | III. Treatment Techniques | 20% |
Ten points moved from planning to technique. Treatment Planning now splits into choosing treatment methods (25%) and choosing points (15%). Treatment Techniques splits into acupuncture (15%), moxibustion (5%), and adjunctive therapies (10%). Point location moved to the top of the outline but kept its 15%.
How to adjust: give technique the time it now earns. Needling, moxibustion, and adjunctive therapies are 30% of your score, up from 20%, so they deserve more than a quick review the week before.
Foundations of Oriental Medicine (FOM)
| 2026 domain | 2026 weight | Closest 2020 domain | 2020 weight |
|---|---|---|---|
| I. Patient Assessment Methods | 28% | I. Clinical Examination Methods | 35% |
| II. Pathomechanisms and Pattern Differentiation | 38% | II. Assessment, Analysis, and Differential Diagnosis Based Upon Acupuncture and Chinese Medicine Theory | 35% |
| III. Treatment Planning | 34% | III. Treatment Principle and Strategy | 30% |
Weight moved from gathering findings to using them. Pattern differentiation and treatment planning are now 72% of the exam, up from 65%. The 2026 outline also gives each of the four diagnostic methods its own weight: asking 10%, palpation 9%, looking 6%, and listening and smelling 3%.
How to adjust: know your tongue and pulse findings, but spend most of your time going from findings to a pattern, and from a pattern to a treatment principle.
Biomedicine (BIO)
| 2026 domain | 2026 weight | Closest 2020 section | 2020 weight |
|---|---|---|---|
| I. Biomedical Sciences | 18% | Biomedical sciences, pharmacology, and supplements (part of I. Biomedical Model) | 25% |
| II. Patient Evaluation | 26% | Patient history and physical examination (part of I. Biomedical Model) | 20% |
| III. Analysis and Clinical Decision-making | 34% | Clinical assessment process, plus clinical decision-making and standard of care (part of I. Biomedical Model) | 35% (30% + 5%) |
| IV. Professional Responsibilities | 22% | II. Safety and Professional Responsibilities | 20% |
Biomedicine's structure changed the most. The 2020 outline put 80% of the exam in one Biomedical Model domain; the 2026 outline splits it into three. The basic sciences drop from 25% to 18% (anatomy, physiology, and pathophysiology 6%, pharmacology 7%, supplements 5%). Patient evaluation rises to 26%, and the physical exam alone is 14%. Professional Responsibilities now lists a weight for each part: professional and ethical conduct 5%, emergency management 5%, communication and collaboration 4%, infection control and workplace safety 3%, records management and reporting 3%, and insurance and billing 2%.
How to adjust: spend less time on pure science and more on clinical work: taking a history, examining, reading test results, and deciding what to do next. Don't skip the professional-responsibility material. At 22%, it is worth more than the basic sciences.
Chinese Herbology (CH)
| 2026 domain | 2026 weight | Closest 2020 domain | 2020 weight |
|---|---|---|---|
| I. Chinese Herbs, Herbal Combinations and Herbal Formulas | 22% | II. Treatment Planning and Strategies | 70% for the whole domain |
| II. Safety and Quality Control | 24% | I. Safety and Quality of Chinese Herbs | 10% |
| III. Treatment Planning and Administration | 30% | II. Treatment Planning and Strategies | (same 70% domain) |
| IV. Treatment Evaluation and Modification | 24% | III. Patient Management | 20% (evaluation and modification was one of three parts) |
This is the biggest shift on any of the four exams. Safety and quality control more than doubled, from 10% to 24%. Treatment evaluation and modification, once one part of a 20% patient-management domain, is now its own domain at 24%. Herb and formula knowledge (individual herbs and combinations 11%, formulas 11%) plus treatment planning and administration (formulation 22%, administration 8%) now total 52%, down from the old 70% treatment-planning domain.
How to adjust: safety is no longer a side topic. At nearly a quarter of the exam, cautions, contraindications, interactions, and quality issues belong in your daily review, not the last week. Practice changing a formula as the patient's presentation changes, too; evaluation and modification now counts as much as safety. For a full study approach, see the Chinese Herbology board prep guide.
What's new and what's gone, line by line
The weights show where the points are. The topic lists show what moved. Here is what changed when I compared the 2020 and 2026 outlines item by item.
Foundations of Oriental Medicine
- Pattern differentiation now asks for the underlying pathomechanism, not just the pattern.
- The Chinese organ clock moved here from the old ACPL outline.
- Treatment planning adds explaining your findings and the plan to the patient. Self-care advice such as qi gong and tai ji, and dietary recommendations, stay.
Acupuncture with Point Location
- Professional practice and case management are gone from ACPL. Patient education, prognosis, referral, discharge, and collaborating with other providers no longer appear; discussing treatment expectations is what remains.
- Asian bodywork is no longer its own section. Tuina and acupressure are now listed with the adjunctive therapies.
- Myofascial trigger point (MTrP) technique is now its own needling item. The 2020 outline mentioned myofascial treatments only under treatment planning.
- Dropped: the item on acupuncture's effects on blood flow, neurohormonal regulation, and brain connectivity; Root and Branch theory (still in Foundations); and the organ clock.
Biomedicine
- Clinical decision-making now names medical necessity, social determinants of health, evidence-based information, and discharge as a case-management option.
- Diagnostic tests now include recognizing the need for preventive screening.
- Professional responsibilities now cite the NCBAHM Code of Ethics and add billing alongside insurance. Insurance, ICD and CPT coding, and emergency protocols were already in the 2020 outline; now each area has its own weight.
Chinese Herbology
- Safety adds ethical issues and an item on the U.S. regulatory framework (cGMP standards, FDA oversight, certificates of analysis).
- New: deciding when a patient needs co-management or referral, and adjusting the herbal plan for pediatric, geriatric, pregnant, and menstruating patients.
- Two new appendices list herbal pairs (Dui Yao) and obsolete substances.
- Dropped: Chinese dietary therapy. Dietary recommendations remain in the Foundations outline.
What did not change
- The four modules. Foundations of Oriental Medicine, Acupuncture with Point Location, Biomedicine, and Chinese Herbology are still separate exams.
- The format. Each module is a computer-adaptive exam of 100 multiple-choice questions on a 2.5-hour clock, and every answer shapes the difficulty of the next one. You can't go back and change earlier answers.
- The passing standard. Scores are scaled from 1 to 99, and NCBAHM requires a scaled score of 70 to pass.
- Your credential. Certifications earned under the NCCAOM name remain valid under NCBAHM. For the full story on the rename, see NCBAHM vs NCCAOM: What's the Difference in 2026?
If you studied under the old outline
- Download the 2026 outline for your module from NCBAHM and keep it open while you plan. NCBAHM calls the outline the primary study resource.
- Re-map your notes. List the new domains and file each topic you have studied under one of them. The gaps show up fast.
- Re-weight your hours. Give each domain study time in proportion to its new weight, not the old one.
- Practice applying, not just recalling. The domains that gained weight are about using knowledge on a patient, so drill case-style questions where you pick the pattern, the treatment, or the safest next step.
- Check every prep resource's outline version. A question bank, flashcard deck, or course written before 2026 may still be organized and weighted around the old outline. Ask which outline it follows.
- Take a timed practice test before you book. NCBAHM offers official practice tests, and a timed run shows whether your weak domains are the heavy ones.
The first-try playbook still applies; only the map changed.
How AcuPass handles the new outlines
AcuPass is built on the 2026 outlines. Questions are tagged to the new domains, your score estimate is weighted by the new percentages, and your study plan sends more days to the domains that count most and that you miss most. Every question is checked against source texts by a DACM before you see it. Here's how the method works.
If you are testing soon, start with the free readiness assessment: 20 questions spread across the domains by their 2026 weights, a score estimate, and a domain map, with no card required. See where you stand →

Frequently asked questions
When did the new NCBAHM content outlines take effect?
They apply to every NCBAHM exam administered on or after September 1, 2026, in all four modules: Foundations of Oriental Medicine, Acupuncture with Point Location, Biomedicine, and Chinese Herbology.
Did the NCCAOM exam change in 2026?
Twice. In January 2026 the NCCAOM renamed itself the National Certification Board for Acupuncture and Herbal Medicine (NCBAHM). Then, from September 1, 2026, every module moved to new content outlines based on NCBAHM's 2024 job analysis.
Which module changed the most?
Chinese Herbology. Safety and quality control went from 10% of the exam to 24%, and treatment evaluation and modification, once one part of a 20% patient-management domain, is now its own domain at 24%. Biomedicine changed shape too: its single 80% Biomedical Model domain was split into three domains.
Are there new topics on the exam?
A few. Comparing the 2020 and 2026 outlines line by line, new items include medical necessity and social determinants of health in Biomedicine, co-management, referral and the U.S. regulatory framework in Chinese Herbology, and a myofascial trigger point technique item in Acupuncture with Point Location. Chinese dietary therapy was dropped from the Herbology outline. NCBAHM itself describes the most notable change as a reorganization of content domains.
I studied with the old outline. Do I need to start over?
No. Most of what you studied still counts. Map your notes onto the new domains, move study time toward the domains that gained weight, and check the 2026 topic list for anything you haven't covered.
Where can I download the new content outlines?
NCBAHM's Job Analysis page links the 2026 outline for each module, and its Exam Preparation Center has the candidate handbooks. NCBAHM calls the outline the primary study resource; it doesn't require a single textbook or endorse any third-party prep product.
