The One-Page Snapshot: Exam Format and Logistics
The Certified Health Unit Coordinator credential, styled C.H.U.C., is awarded by the Certification Board of the National Association of Health Unit Coordinators, Inc. (NAHUC). If you only have a few minutes before your next study session, this cheat sheet is built to give you the facts that matter most: how the exam is built, what it costs, what each domain tests, and the rules that trip up candidates on test day.
Start with the format. The exam is delivered through TesTrac, either with an approved independent in-person proctor or with a webcam remote proctor. You will face 120 multiple-choice questions, each with four answer choices and one best answer. Of those 120 items, 100 are scored and 20 are unscored pretest items that NAHUC uses to evaluate future questions. You will not know which are which, so treat every question as if it counts. Total testing time is 150 minutes.
| Exam Element | What to Know |
|---|---|
| Certifying body | NAHUC Certification Board |
| Delivery | TesTrac, in-person proctor or webcam remote proctor |
| Total questions | 120 multiple-choice |
| Scored / unscored | 100 scored, 20 unscored pretest items |
| Answer format | Four choices, one best answer |
| Time limit | 150 minutes |
| Reference materials | Closed book; calculators prohibited |
The phrase "one best answer" matters. Several options on a question may be partially correct, and your job is to select the most appropriate response for a health unit coordinator working within the scope of the role. For a deeper look at how the questions feel, see How Hard Is the CHUC Exam? Complete Difficulty Guide 2026.
Fees, Eligibility, and Registration Facts
Cost Quick Reference
- Exam fee: $205 USD.
- Optional NAHUC practice test: 50 questions, $20 for members or $40 for non-members, single use. This is a separate purchase and is not part of certification testing.
- Membership: optional. You do not need to be a NAHUC member to sit for the exam.
Budgeting beyond the exam fee depends on the study materials you choose; our CHUC Certification Cost 2026: Complete Pricing Breakdown walks through the full picture.
Eligibility Quick Reference
Candidates need a high-school diploma or equivalent plus at least one qualifying pathway: unit-coordination work, relevant support duties, health unit coordinator (HUC) training, or involvement in health unit coordinating activities. That flexibility means working coordinators, career changers who completed HUC training, and people in adjacent support roles can all qualify. The details, including how to document your pathway, are covered in CHUC Requirements 2026: Eligibility, Prerequisites & How to Qualify.
The Four Domains at a Glance
The January 2026 candidate handbook retains the content outline effective June 1, 2018. That means the domain structure and weights you see below are current, and older study materials built around this outline remain relevant as long as you verify them against the handbook.
| Domain | Weight | Approx. Scored Items* |
|---|---|---|
| 1. Order Management | 17% | about 17 of 100 |
| 2. Coordination of Health Unit, Equipment, and Technical Procedures | 41% | about 41 of 100 |
| 3. Communication/Customer Service | 28% | about 28 of 100 |
| 4. Professional Development | 14% | about 14 of 100 |
*Derived by applying the published weights to the 100 scored questions; the pretest items are unscored and unidentified.
Notice the shape of the exam: Domain 2 plus Domain 3 together account for 69% of the content. If your time is limited, that is where your review hours produce the greatest return. For a full breakdown of each area, read CHUC Exam Domains 2026: Complete Guide to All 4 Content Areas.
Domain 1 Review: Order Management (17%)
Order Management
This domain covers how physician and provider orders move from the point of entry to the people and departments that carry them out. It is the transcription-and-processing heart of the role.
- Interpreting orders accurately, including recognizing standard medical terminology and common abbreviations
- Processing, transcribing, and communicating orders to the correct department or caregiver
- Recognizing incomplete, unclear, or conflicting orders and knowing to seek clarification rather than assume
- Understanding which tasks fall within the health unit coordinator's scope and which must be routed to licensed clinical staff
- Tracking order status, results, and follow-up so nothing falls through the cracks
At 17%, this domain is smaller than people expect given how central orders are to daily work. Expect scenario questions: an order is ambiguous, a result needs to be routed, or a request falls outside coordinator scope. The "best answer" is usually the one that protects patient safety by clarifying or escalating rather than guessing.
Domain 2 Review: Coordination of Health Unit, Equipment, and Technical Procedures (41%)
This is the largest domain on the exam, and it earns that status because it describes what a unit coordinator actually does hour by hour. Four in every ten scored questions come from here, so weakness in this area is very hard to offset elsewhere.
Coordination of Health Unit, Equipment, and Technical Procedures
Think of this domain as running the nerve center of a patient care unit: keeping information, supplies, equipment, and technology flowing so clinical staff can focus on patients.
- Managing patient records and charts, including admissions, transfers, and discharges at the unit level
- Coordinating supplies, inventory, and equipment so the unit stays stocked and functional
- Operating unit technology such as electronic health record systems, communication devices, and other office equipment
- Scheduling and coordinating diagnostic tests, procedures, and consults with other departments
- Maintaining confidentiality and following privacy and documentation standards
- Supporting unit safety, infection-control awareness, and emergency procedures within the coordinator's role
Candidates who work as unit coordinators often feel comfortable here but are surprised by the breadth. Procedures you perform daily may be phrased in textbook terms on the exam, so review the formal vocabulary even for tasks you do on autopilot. Our CHUC Study Guide 2026: How to Pass on Your First Attempt maps these topics to study resources.
Domain 3 Review: Communication/Customer Service (28%)
Communication/Customer Service
The second-largest domain tests how well you handle people: patients, families, nurses, physicians, and other departments, often under pressure.
- Professional telephone and in-person communication, including taking accurate messages and routing calls
- Responding to patient and visitor requests with courtesy while respecting scope of practice
- Handling complaints, conflict, and upset individuals calmly and appropriately
- Therapeutic and clear communication with diverse populations, including attention to cultural sensitivity
- Protecting patient privacy in conversations, on the phone, and in shared spaces
- Using the right channel and level of urgency when relaying information to the care team
On this domain, the best answer tends to combine empathy, professionalism, and boundaries. A coordinator can be warm and helpful without giving clinical advice or disclosing protected information. When a question puts you between a frustrated family member and a policy, look for the response that stays courteous, stays within scope, and directs the person to the right resource.
Domain 4 Review: Professional Development (14%)
Professional Development
The smallest domain still carries roughly 14 scored questions, which can easily decide a borderline result.
- Understanding the health unit coordinator role, its scope, and its place in the healthcare team
- Ethical and legal responsibilities, including confidentiality and professional boundaries
- Continuing education and the value of maintaining certification
- Workplace conduct, time management, and teamwork expectations
- Awareness of professional organizations and growth opportunities in the field
Do not skip this domain because it is the smallest. The questions are often the most approachable on the exam, which makes them valuable points for candidates who prepare even a little. Pair this review with CHUC Certification for background on how the credential fits into a career path.
Test-Day Rules You Cannot Forget
- Bring two forms of identification. Verify the specific ID requirements in the candidate handbook well before test day.
- Expect a closed-book exam. No notes, references, or study aids.
- Leave the calculator behind. Calculators are prohibited, so nothing on the exam should require one.
- Know your proctoring format. In-person proctors and webcam remote proctors follow different check-in procedures, so confirm which applies to you and prepare your space or travel accordingly.
- Pace yourself across 150 minutes. With 120 questions, you have a bit over a minute per item. Mark difficult questions, move on, and return if time allows.
- Answer every question. With four choices and one best answer, an educated guess always beats a blank.
Key Takeaway
Because 20 of your 120 questions are unscored pretest items, a strange or unusually difficult question may be one of them. Do not let a single baffling item rattle your confidence or eat your clock; make your best choice and move on.
Renewal Cycles and Contact Hours
Certification is not permanent, so factor renewal into your long-term plan. The rules depend on when your cycle begins:
| Cycle Start | Length | Renewal Requirement |
|---|---|---|
| January 1, 2026 or later | Two years | 24 NAHUC contact hours, or reexamination |
| Earlier three-year cycles | Three years (existing expiration retained) | 36 hours until the next cycle begins |
In plain terms: if you certify in 2026, you will be on the shorter two-year clock with 24 contact hours or reexamination. If you already hold the credential under an earlier three-year cycle, your current expiration date and 36-hour requirement remain in place until your next cycle starts. Keep records of your contact hours as you earn them rather than scrambling at the end of a cycle.
A Domain-Weighted Review Plan
Rather than generic scheduling advice, let the exam blueprint decide your calendar. Here is a four-week approach that allocates time roughly in proportion to domain weight, with Domain 2 taking the largest share.
Domain 2, Part One
- Review chart management, admissions, transfers, and discharges
- Study unit supplies, equipment coordination, and technology systems
- Take a short quiz on unit workflow scenarios
Domain 2, Part Two plus Domain 1
- Finish scheduling and procedure coordination topics
- Review order interpretation, transcription, and clarification rules
- Drill medical terminology and abbreviations
Domains 3 and 4
- Practice communication and customer-service scenarios with scope-of-practice boundaries
- Review ethics, confidentiality, and professional role content
- Revisit weak spots from earlier quizzes
Full-Length Practice
- Complete timed practice sets that mirror 120 questions in 150 minutes
- Review every miss by domain to find patterns
- Confirm ID, proctoring setup, and test-day logistics
For timed practice that matches the real exam's multiple-choice style, try the CHUC practice test and review your results by domain. If you also plan to purchase NAHUC's 50-question practice test, remember it is a separate, single-use product, so save it for when you are ready to measure yourself honestly. For a sense of how scores are determined, see CHUC Passing Score 2026: Exactly What You Need to Pass; NAHUC uses Angoff standard setting and form equating, which is why the pass line is tied to a defined standard of competence rather than a simple raw-percentage cutoff.
Where Certified Health Unit Coordinators Work
The credential is built around the unit-level administrative and communication role in patient care settings. Hospitals are the most recognizable employer, where coordinators work on nursing units, emergency departments, surgical areas, and specialty floors. Beyond acute care, health unit coordinator skills transfer to outpatient clinics, long-term care facilities, rehabilitation centers, and physician practices that need someone to manage orders, records, and communication flow.
Because the exam emphasizes order management, unit coordination, and communication, the credential signals to employers that you can keep a busy unit organized and connected.
