1.1 NCBAHM Certification Pathways & Exam Logistics

Quick Answer: The National Certification Board for Acupuncture and Herbal Medicine (NCBAHM), formerly the National Certification Commission for Acupuncture and Oriental Medicine (NCCAOM), awards the Diplomate of Acupuncture (Dipl. Ac.) after a candidate passes three core modules: Foundations of Oriental Medicine (FOM), Biomedicine (BIOM), and Acupuncture with Point Location (ACPL). Each module is a computer-adaptive test (CAT) of 100 multiple-choice items in 2.5 hours at a Pearson VUE test center. Results use a scaled score from 1 to 99, with 70 as the passing standard. Exams taken on or after September 1, 2026 follow the 2026 content outlines based on the 2024 Job Analysis. The acupuncture application costs $550 and each exam costs $350, a total of $1,600 for the three core modules. NCBAHM certification or exams are required for licensure in 46 states plus the District of Columbia; California licenses through its own California Acupuncture Licensing Examination (CALE).

From NCCAOM to NCBAHM

NCBAHM was founded in 1982 as a non-profit certification organization and was formerly known as NCCAOM. The 2026 Acupuncture Candidate Preparation Handbook reports more than 21,000 active Diplomates. Its certification programs are accredited by the National Commission for Certifying Agencies (NCCA). Many state statutes and board rules still say "NCCAOM." Boards treat that wording as a reference to the same organization and its examinations, but always confirm current wording with the board in the state where you will practice.

The name change did not change the exam content, the test vendor, or the scoring model. Expect older study materials, school handouts, and some state forms to use NCCAOM and the older credential names.

Certification Programs and Required Modules

This guide covers the three acupuncture core modules. Chinese Herbology is a separate examination with its own content outline.

Eligibility and the Authorization to Test

Most candidates qualify through Route 1: Formal Education (United States Applicant):

1. Create an account in the NCBAHM Certification Portal and submit the application. Students may begin about 60 days before graduation.
2. Arrange for the graduate transcript to be sent by the school and the Clean Needle Technique (CNT) Certificate to be sent by the Council of Colleges of Acupuncture and Herbal Medicine (CCAHM).
3. When both documents are received and the application is approved, NCBAHM issues an Authorization to Test (ATT) letter. Only then can you schedule with Pearson VUE.

All required examinations must be completed and passed within four years of the application submission date (2026 Examination FAQ).

Exam Format and the 2026 Content Outlines

Each module has 100 items and a 2.5-hour (150-minute) limit. Every exam includes a limited number of pretest items. These are new questions being trialed for future use. They do not count toward your score, and you cannot tell them apart from scored items. All items are written to a task statement on the content outline. NCBAHM's item-writing guidelines tell committees to avoid negatively worded stems such as "NOT" or "EXCEPT."

The 2026 content outlines apply to every examination taken on or after September 1, 2026. Candidates who tested before that date were assessed under the 2020 outlines. Use the 2026 domain weights below to plan your study time.

Two features of the 2026 outlines deserve attention. Treatment planning is the largest ACPL domain (40%) and a major FOM domain (34%, second only to pattern differentiation at 38%). In BIOM, analysis and clinical decision-making (34%) outweighs any single science area. The exams reward applying knowledge to a patient more than reciting facts.

Test Day at Pearson VUE

Arrive early. Candidates who arrive after their appointment time are not admitted and forfeit the exam fee. Bring:

1. The NCBAHM Authorization to Test (ATT) letter. You can reprint it from the portal.
2. A current driver's license or government ID with photo and signature.
3. A second current ID with a signature (for example a school, work, or credit card).

The name on the photo ID must exactly match the ATT letter. Staff photograph you and perform a palm vein scan. All personal items go in a locker, including wallets, phones, coats, food, watches, and smart glasses. If your prescription glasses are smart glasses, bring a standard pair or you will be turned away. The center provides a ring binder of five erasable sheets and a marker, collected at the end. Testing is audio and video recorded.

At the workstation you have five minutes to accept the Non-Disclosure Agreement (NDA). Do not write on the note board until the exam has started. Writing during the NDA terminates the session, and the fee is forfeited.

Scheduling, Rescheduling, and Cancelling

• Schedule through Pearson VUE after you receive your ATT. NCBAHM exams are offered at more than 250 Pearson VUE professional test centers.
• Cancel or reschedule at least one full business day (24 hours) before your appointment.
• The initial application includes three free cancellations or reschedules per examination. After the third, you must sit the rescheduled appointment or be marked a no-show and forfeit the fee. Additional changes are available for a nominal fee.

Scoring and Results

NCBAHM reports a scaled score from 1 to 99, with 70 as the passing standard. A scaled score is not a percentage correct. Your raw performance is weighted by item difficulty and converted to the common scale, so every candidate faces the same standard regardless of which items appeared. The passing standard is set by practicing, licensed, board-certified acupuncturists in a standard-setting study.

• You see a preliminary pass or fail result on screen when you finish.
• The official result letter is uploaded to your portal account within 7-10 days.
• A pass letter shows no numeric score.
• A fail letter shows the overall scaled score and a breakdown by content area. Content-area scores cannot be averaged to produce the overall score, because each area has a different number of items.
• You may request score verification within 30 days of a failing result (nominal fee). Concerns about a specific item can be noted on an incident report at the test center and submitted in writing within 30 days.

Fees (2026)

After certification, Diplomates recertify every four years, which requires 60 PDA points and a current CPR certificate.

Retake Rules

For initial certification, passed exams remain valid for 12 years from the date taken.

Published First-Time Pass Rates

NCBAHM publishes first-time pass rates for Route 1 (United States formal-education) candidates:

Biomedicine has the lowest first-time pass rate of the three acupuncture core modules. Budget extra study time for it, even if biomedical sciences felt easier in school.

State Licensure and the California Exception

NCBAHM is a national certification body, not a licensing agency. Licensure is granted by each state. NCBAHM certification or its examinations are required for acupuncture licensure in 46 states plus the District of Columbia. Some states require active certification; others accept passed exams. Herbal-scope states may also require Chinese Herbology.

California licenses through the California Acupuncture Board, which requires its own California Acupuncture Licensing Examination (CALE). NCBAHM certification does not replace the CALE, and holding a California license does not exempt anyone from NCBAHM requirements. When you apply for licensure, request results verification through the portal ($60 per state) so NCBAHM sends your results directly to the board.
