The Short Answer: A CHUC Is a Credential, Not Just a Job Title
A CHUC is a Certified Health Unit Coordinator: a health unit coordinator who has passed the certification examination administered by the National Association of Health Unit Coordinators, Inc. (NAHUC). The designation is also written C.H.U.C. It signals that the holder has demonstrated competence in the nonclinical coordination work that keeps a patient care unit running.
The distinction matters. "Health unit coordinator" describes a role: the person at the heart of a nursing unit who processes orders, answers communications, manages paperwork, and keeps information flowing between patients, families, nurses, physicians, and ancillary departments. "CHUC" describes a professional credential that someone in that role (or preparing for it) can earn by passing a standardized exam.
This article explains what the credential is, how the exam is structured, what it costs, how to qualify, and how to prepare. If you already know the basics and want a deeper dive, jump to our CHUC study guide or the complete guide to all four CHUC exam domains.
Who Awards the Certification
The credential is granted through the NAHUC Certification Board, which operates under the National Association of Health Unit Coordinators, Inc. The exam itself is delivered through TesTrac, using either an approved independent in-person proctor or a webcam-based remote proctor, so candidates have a choice between testing in a physical setting and testing from an approved remote environment.
Two technical details are worth knowing because they affect how you interpret your result:
- Angoff standard setting: the passing standard is determined by subject-matter experts judging how a minimally competent candidate would perform on each item, rather than by curving against other test takers.
- Form equating: because different candidates may see different versions of the exam, equating is used so that the passing standard stays comparable across forms.
In practical terms, your outcome depends on your own mastery of the content outline, not on how well others did that week. For more on how scoring works, see our breakdown of the CHUC passing score.
What Health Unit Coordinators Actually Do
The exam is built around the real work of a unit coordinator, so understanding that work is the fastest way to understand the test. Health unit coordinators do not provide hands-on clinical care. Instead, they run the information and logistics layer of the unit:
- Transcribing and processing physician orders into the unit's systems and communicating them to the right departments
- Answering call lights, phones, and intercom traffic and routing messages appropriately
- Greeting patients, visitors, and families and directing them with professionalism
- Preparing and maintaining patient charts and handling admission, transfer, and discharge paperwork
- Scheduling tests and procedures and coordinating transport and equipment needs
- Ordering and stocking supplies and keeping the unit environment functional
This is why the exam leans heavily on coordination, communication, and order handling rather than on clinical decision-making. If you are exploring the field itself, our pages on CHUC jobs and CHUC training cover career paths and preparation routes in more detail.
How the Exam Is Built
The CHUC exam is a computer-based, multiple-choice test with a very consistent structure. Knowing the mechanics ahead of time removes one source of test-day stress.
| Exam Feature | Detail |
|---|---|
| Total questions | 120 multiple-choice items |
| Scored questions | 100 |
| Unscored pretest questions | 20 |
| Answer choices | Four options, one best answer |
| Testing time | 150 minutes |
| Delivery | TesTrac, with in-person proctor or webcam remote proctor |
| Book/calculator policy | Closed book; calculators prohibited |
The unscored pretest items
Twenty of the 120 questions are pretest items used to evaluate future exam content. They are not counted toward your score, and you will not be told which ones they are. The practical lesson: treat every question as if it counts, and do not waste time trying to guess which items are "the experimental ones."
"One best answer" thinking
Each item gives four choices with a single best answer. On a coordination-focused exam, more than one option can sound reasonable. The correct choice is usually the one that follows proper procedure, protects the patient, and routes information or tasks to the right person. Practice reading the stem for the real priority: what should the coordinator do first, who should be notified, or which action stays within the scope of the role?
The Four Content Domains
The exam is organized into four domains with fixed weights. The January 2026 candidate handbook retains the content outline effective June 1, 2018, so the domain structure below is the one to study against.
Domain 1: Order Management (17%)
This domain covers how orders move from physician intent to completed action.
- Interpreting, transcribing, and processing different types of orders accurately
- Recognizing when an order is unclear or incomplete and knowing to seek clarification
- Communicating orders to the correct departments and tracking follow-through
- Understanding the terminology and abbreviations that appear in orders
Domain 2: Coordination of Health Unit, Equipment, and Technical Procedures (41%)
The largest domain by a wide margin, and the one that defines the job.
- Coordinating patient admissions, transfers, and discharges at the unit level
- Scheduling and arranging tests, procedures, and consults
- Managing supplies, equipment, and the unit's technical and clerical systems
- Maintaining charts and records according to policy
- Following safety, infection-control, and emergency-awareness procedures that touch unit operations
Domain 3: Communication/Customer Service (28%)
The second-largest domain, covering how the coordinator handles every interaction.
- Professional telephone, intercom, and in-person communication
- Handling patients, families, and visitors with courtesy and appropriate boundaries
- Protecting confidentiality and privacy in every exchange
- Relaying messages accurately among nurses, physicians, and other departments
- Responding to difficult or urgent situations calmly and appropriately
Domain 4: Professional Development (14%)
The smallest domain, but not one to skip.
- Professional conduct, ethics, and scope of practice
- Workplace relationships, teamwork, and accountability
- Continuing education and the role of professional growth
- Understanding the responsibilities that come with credentialed status
| Domain | Weight |
|---|---|
| Order Management | 17% |
| Coordination of Health Unit, Equipment, and Technical Procedures | 41% |
| Communication/Customer Service | 28% |
| Professional Development | 14% |
Key Takeaway
Domains 2 and 3 together account for 69% of the exam. If your study time is limited, make sure unit coordination and communication are rock solid before polishing the smaller domains.
Eligibility and Registration Mechanics
To sit for the exam, you need a high-school diploma or equivalent plus a qualifying connection to the field. That connection can take several forms: unit-coordination work experience, relevant support duties, completion of health unit coordinator training, or involvement in health unit coordinating activities. NAHUC membership is optional, so you do not need to join the association to test.
That flexible eligibility pathway means the credential is accessible to experienced coordinators who learned on the job as well as to newer entrants coming out of a training program. For a fuller walk-through of the prerequisites, read our guide to CHUC requirements, and for scheduling logistics see CHUC exam dates and scheduling.
Accommodations
If you need testing accommodations, request them at least 45 calendar days before your intended exam date. Build that lead time into your plan; waiting until the last month can force you to push your date back.
Retesting
If you do not pass on your first attempt, there is a 60-day wait before you can retest. Use that window deliberately: review which domains gave you the most trouble, and rebuild your preparation around them. Our article on how hard the CHUC exam is discusses what tends to trip candidates up.
What It Costs
The CHUC exam fee is $205 USD. Separately, NAHUC offers an optional 50-question practice test that costs $20 for members or $40 for non-members for single use. That practice test is distinct from certification testing and does not count toward your credential.
| Item | Cost |
|---|---|
| CHUC certification exam | $205 USD |
| NAHUC 50-question practice test (member) | $20, single use |
| NAHUC 50-question practice test (non-member) | $40, single use |
When you budget, remember to account for the possibility of a retest and for any study materials you choose to buy. For the full financial picture, including the long-term payoff, see our CHUC certification cost breakdown and the analysis of whether the CHUC certification is worth it. If you want free, unlimited-style repetition on exam-style questions, our CHUC practice test is designed to complement NAHUC's own offerings.
Test-Day Rules You Need to Know
Because the exam is proctored, whether in person or by webcam, the rules are strict and worth reviewing before you register.
- Closed book: no notes, references, or outside materials during the exam
- No calculators: calculators are prohibited, so you will not need them, and you should not bring one
- Identification: bring two forms of identification
- Proctor approval: your in-person proctor must be an approved independent proctor, and remote testing uses a webcam proctor
Staying Certified: The Renewal Cycle
Earning the credential is not a one-time event. Certification renewal is built around a defined cycle, and the rules depend on when your cycle begins.
| Cycle | Length | Renewal Requirement |
|---|---|---|
| Cycles beginning January 1, 2026 or later | Two years | 24 NAHUC contact hours or reexamination |
| Earlier cycles | Three years | 36 hours, retained until the next cycle |
Earlier three-year cycles keep their existing expiration date and 36-hour requirement until the next cycle begins. Once you enter a cycle that starts on or after January 1, 2026, the shorter two-year cycle and 24-hour requirement apply. Either way, the option to renew by reexamination gives you a route if you fall short on contact hours.
Where CHUCs Work
Health unit coordinators are found wherever there is a patient care unit that needs organized nonclinical support. Typical employers and settings include:
- Acute-care hospitals, across medical-surgical, critical care, emergency, maternity, pediatric, and other specialty units
- Long-term care and skilled nursing facilities
- Rehabilitation hospitals and units
- Outpatient surgical centers and ambulatory clinics with unit-style workflows
- Behavioral health facilities
Employers often value the credential as a signal of standardized competence, particularly when hiring for busy units where order accuracy and clear communication directly affect patient safety.

A Domain-Weighted Study Sequence
You do not need an elaborate system. What matters is aligning your time with the domain weights. Here is one way to sequence a four-week plan around the content outline.
Coordination of Health Unit, Equipment, and Technical Procedures (41%)
- Start with the biggest domain so you have the longest runway to absorb it
- Cover admissions, transfers, discharges, scheduling, supplies, and chart maintenance
- Take a short exam-style quiz on this content at the end of the week
Communication/Customer Service (28%)
- Review telephone and in-person communication standards
- Practice confidentiality and privacy scenarios
- Work through "what should the coordinator do first?" situational questions
Order Management (17%) and Professional Development (14%)
- Drill order types, terminology, and clarification procedures
- Review ethics, scope of practice, and professional conduct
- Revisit Week 1 weak spots
Integrated Practice
- Take full-length mixed-domain practice sets under timed, closed-book conditions
- Review every missed question and trace it back to its domain
- Rest the day before your exam
Why this order? Domains 2 and 3 are 69% of the exam, so they deserve the earliest and most concentrated attention. Order Management and Professional Development are smaller but still worth meaningful points, and they pair well because each is more procedural and definitional.

Key Takeaway
Practice under the real conditions: closed book, no calculator, one best answer among four choices, and a 150-minute clock. Our CHUC practice test is built to mirror that format so test day feels familiar.
