The Short Answer: Certified Health Unit Coordinator
CHUC stands for Certified Health Unit Coordinator. It is a professional certification for people who run the non-clinical, communication-heavy side of a hospital nursing unit or similar patient care area: the person at the desk who transcribes and processes orders, answers the phones, coordinates equipment and supplies, routes information among nurses, physicians, and other departments, and keeps the unit's operations moving.
Because many acronyms in healthcare and other industries overlap, it is worth being precise. On this site, and in this article, CHUC refers only to the health unit coordinator credential. If you are here to understand the exam itself, you can start with our overview of what CHUC certification is, then come back for the breakdown below.
Who Awards the Credential
The certification is administered by the National Association of Health Unit Coordinators, Inc. (NAHUC) through its Certification Board. NAHUC is the professional association for health unit coordinators, and its Certification Board is the body that sets the content outline, standards, and renewal rules for the credential.
The exam itself is delivered through TesTrac, which supports testing with an approved independent in-person proctor or a webcam remote proctor. That means candidates have more flexibility than a fixed testing-center model might suggest, though you must still follow the proctoring and identification rules in the candidate handbook. For scheduling specifics, see our guide to CHUC exam dates, testing windows, and deadlines.
NAHUC membership versus certification
One common point of confusion is whether you must join NAHUC to certify. You do not. Membership is optional for eligibility. Membership does matter in one small way: NAHUC's optional practice test is priced lower for members than for non-members (more on that below).
How the Letters Are Written and Used
Certified coordinators typically place the designation after their name on badges, email signatures, and resumes. You will see it written as CHUC, and the association also styles it with periods as C.H.U.C. Both refer to the same credential.
Employers may also reference the credential in job postings, sometimes listing it as preferred or required, and sometimes alongside phrases like "unit secretary" or "unit clerk." Job titles vary by facility, but the certification speaks to a defined competency outline rather than a local title. If you are exploring openings, our page on CHUC jobs covers how the credential shows up in hiring.
| Form | What it means | Where you will see it |
|---|---|---|
| CHUC | Certified Health Unit Coordinator | Resumes, badges, job postings |
| C.H.U.C. | Same credential, written with periods | NAHUC materials and formal usage |
| HUC | Health unit coordinator (the role, not the certification) | Job titles, training programs |
That last row matters: HUC is the job, while CHUC is the person who has earned the certification. If you want a plain-language definition of the job title itself, read what a CHUC is.
What a Health Unit Coordinator Actually Does
The title explains the function. A health unit coordinator coordinates the activity of a health unit. In practice that includes several recurring responsibilities:
- Order processing: receiving, transcribing, and communicating physician and provider orders accurately so the right department acts on them.
- Unit operations: managing the flow of patient information, charts, and supplies; coordinating equipment and technical procedures.
- Communication hub: answering calls, directing visitors, relaying messages, and handling interactions with patients, families, and interdisciplinary staff with professionalism.
- Professional conduct: maintaining confidentiality, working within scope, and continuing to develop skills.
Notice that these map almost directly to the exam's four content areas. The certification is designed to confirm that a coordinator can perform these tasks safely and consistently. Training pathways exist for people entering the field; see our overview of CHUC training for how candidates typically prepare for the role.
What the Certification Exam Looks Like
Understanding the format is part of understanding what the letters represent, because the exam is how the credential is earned. Here is the structure:
| Feature | Detail |
|---|---|
| Total questions | 120 multiple-choice |
| Scored questions | 100 |
| Unscored pretest items | 20 (indistinguishable from scored ones) |
| Answer choices | Four options, one best answer |
| Testing time | 150 minutes |
| Delivery | TesTrac, with in-person or webcam remote proctor |
| Rules | Closed book; calculators prohibited; bring two forms of identification |
The phrase "one best answer" is important. Several options may look plausible, and your job is to pick the response that best reflects correct practice for a health unit coordinator. Because 20 questions are unscored pretest items and you cannot tell which ones they are, treat every question as if it counts.
Passing standards are set using Angoff standard setting and form equating, which is a way of keeping the difficulty comparable across different exam forms. For a deeper look at how that plays out, see our explanation of the CHUC passing score, and for perspective on difficulty, how hard the CHUC exam is.
The Four Exam Domains Behind the Title
The January 2026 candidate handbook retains the content outline effective June 1, 2018. That outline divides the exam into four weighted domains. Each one corresponds to a piece of what the "Coordinator" in the title is responsible for.
Domain 1: Order Management (17%)
This domain covers how orders are received, interpreted, transcribed, and communicated.
- Accuracy when processing and relaying orders
- Recognizing which department or role should act on a given order
- Knowing what to clarify before proceeding rather than guessing
Domain 2: Coordination of Health Unit, Equipment, and Technical Procedures (41%)
The largest domain by a wide margin, and the one most closely tied to the day-to-day identity of the role.
- Coordinating unit activities, supplies, and equipment
- Supporting technical procedures and the information flow around them
- Understanding how work on the unit moves between staff and departments
Domain 3: Communication/Customer Service (28%)
The second-largest domain reflects how central communication is to the job.
- Professional telephone and in-person interactions
- Handling patients, families, visitors, and staff appropriately
- Escalating concerns and relaying messages clearly
Domain 4: Professional Development (14%)
The smallest domain, but not one to skip.
- Professional conduct and growth within the role
- Understanding the responsibilities that come with certification
Together, Domains 2 and 3 account for 69% of the outline, so the exam leans heavily toward unit coordination and communication. If you want the full treatment, our complete guide to all four CHUC exam domains goes topic by topic.
Eligibility, Fees, and Registration Mechanics
Knowing what the letters stand for naturally leads to the next question: how do you earn them?
Eligibility
Candidates need a high-school diploma or equivalent plus a qualifying connection to the work. NAHUC recognizes qualifying unit-coordination work, relevant support duties, HUC training, or involvement in health unit coordinating activities. The range of pathways is intentionally broad, so people entering through work experience and people entering through formal training can both qualify. Details are laid out in our guide to CHUC requirements and how to qualify.
Fees and practice testing
- Exam fee: $205 USD.
- NAHUC optional practice test: 50 questions, $20 for members or $40 for non-members for single use. It is separate from certification testing and does not count toward certification.
For a full pricing picture, including how these numbers fit into the broader cost of preparing, see the CHUC certification cost breakdown.
Logistics to plan around
- Accommodations: request them at least 45 calendar days ahead of your exam.
- Retesting: if you do not pass, a 60-day wait applies before you can test again.
- Test day: closed book, no calculators, and two forms of identification.
Key Takeaway
Build your schedule around the 45-day accommodation lead time and the 60-day retest wait. Starting prep early removes pressure if you need to request accommodations, and a realistic plan means you are less likely to need that retest window at all.
Matching Your Prep Time to the Weighting
You do not need an elaborate method. The single most useful idea is to let the content outline decide where your hours go. A simple sequence that follows the weighting might look like this:
Domain 2 first
- Spend the largest block of time on Coordination of Health Unit, Equipment, and Technical Procedures, since it is 41% of the outline.
- Revisit it again later, because breadth here takes repetition.
Domain 3
- Work through Communication/Customer Service scenarios and focus on choosing the single best response.
Domains 1 and 4
- Cover Order Management and Professional Development, then take a timed practice test to rehearse the 150-minute pace.
Our CHUC study guide expands on this approach, and the CHUC cheat sheet is useful for a final-days review. When you are ready to test your recall, you can try questions on the CHUC practice test home page, and the main site also has timed sets that mirror the multiple-choice, best-answer style described above.
Keeping the Credential Active
Earning the letters is not the end of the story. Certification is maintained through a renewal cycle:
- Cycles beginning January 1, 2026 or later last two years, with 24 NAHUC contact hours or reexamination required for renewal.
- Earlier three-year cycles keep their existing expiration date and their 36-hour requirement until the next cycle begins.
The practical meaning: if you certified under the older three-year structure, you are not penalized retroactively. Your current cycle stays as it is, and the new two-year, 24-hour structure applies when your next cycle starts. This ongoing requirement is one reason the Professional Development domain exists in the outline.
Where Certified Coordinators Work
Health unit coordinators are most associated with hospital nursing units, but the coordinating function appears across patient care settings. Typical employers include hospitals and health systems, along with other facilities that run organized patient care units and need someone to manage orders, communication, and unit logistics. Whether the credential is required or simply preferred depends on the employer.
