If you care for patients with pressure injuries, diabetic foot ulcers, venous leg ulcers, or surgical wounds, the Wound Care Certified (WCC)® credential from the National Alliance of Wound Care and Ostomy (NAWCO)® is a recognized way to show that expertise. The exam covers a lot of ground, from lab values and dressing categories to documentation and scope of practice, so it’s normal to feel unsure where to start.

In this guide, we’ll walk you through the exam format, all seven content domains and their weights, the official resources worth downloading, and the questions candidates ask most often.

What Is the NAWCO WCC Exam?

The WCC is a multidisciplinary wound care certification. Unlike some specialty credentials that are limited to one profession, it is open to licensed nurses (RN, LPN/LVN, and APRN), physical and occupational therapists and their assistants, physicians, physician assistants, and podiatrists. The credential is accredited by the National Commission for Certifying Agencies (NCCA), and NAWCO lists that accreditation as current through April 30, 2029.

The exam checks whether you can apply wound care knowledge at the bedside. You’ll need to recognize wound etiology, choose appropriate treatments and products, evaluate whether a plan is working, prevent skin breakdown, teach patients and staff, and document care in a way that holds up legally.

What Is the NAWCO WCC Exam Format?

Here is the exam at a glance, based on the WCC Candidate Examination Handbook (April 2024):

  • Questions: Up to 110 multiple-choice questions.
  • Scored vs. unscored: 100 scored questions and 10 unscored pretest questions. You can’t tell which are which, so give every question your full effort.
  • Time: 2 hours (120 minutes).
  • Delivery: Computer-based testing at Prometric test centers, live remote proctoring (LRP) from your home or office when appointments are available, or paper-and-pencil at scheduled sessions.
  • Scoring: Scaled scores from 100 to 800. The passing score is 600, and NAWCO notes it is not graded on a curve.
  • Results: Computer-based and LRP candidates receive results when they finish. Paper-and-pencil results are emailed within 7 to 10 business days.

With 120 minutes for 110 questions, you have a little over a minute per question. That is comfortable for recall items, but scenario questions about wound bed preparation or product selection can take longer, so practice keeping a steady pace.

What Content Outline Does the NAWCO WCC Exam Use?

The current exam is based on the content outline in the WCC Candidate Examination Handbook dated April 2024. It organizes the exam into seven domains with 44 numbered learning objectives. Here is how the 100 scored questions break down. Because there are exactly 100 scored items, each percentage roughly equals the number of scored questions.

  • Assessment: 27% (about 27 questions)
  • Treatment: 25% (about 25 questions)
  • Re-Evaluation: 16% (about 16 questions)
  • Risk and Prevention: 12% (about 12 questions)
  • Education: 7% (about 7 questions)
  • Administration: 7% (about 7 questions)
  • Legal: 6% (about 6 questions)

Assessment and Treatment together make up more than half of the exam, so they deserve the biggest share of your study time.

Assessment (27%)

This is the largest domain. It covers everything you gather before you choose a treatment: the wound itself, the patient’s health and history, and the risk factors that affect healing.

  • Assess wound etiology and status, including pressure, diabetic, vascular, and surgical wounds.
  • Interpret lab results such as prealbumin, albumin, ESR, A1C, total protein, CMP, and CBC.
  • Assess nutritional status, hydration, psychosocial history, comorbidities, and cognitive and functional status.
  • Assess pain, including onset, location, duration, character, and alleviating factors.
  • Conduct risk assessments with tools such as the Braden, Braden Q, Norton, Wagner, and University of Texas diabetic foot classification.
  • Describe normal and abnormal skin structure and how skin integrity changes from neonates to older adults.

What questions look like: Expect a patient scenario with wound findings and lab values, then a question about the most likely etiology or the most important contributing factor. Knowing the classic features of arterial, venous, neuropathic, and pressure wounds is essential.

Treatment (25%)

Treatment covers choosing and applying therapies, from basic dressings to adjunctive options, and knowing when to refer.

  • Provide wound treatments such as negative pressure wound therapy (NPWT), electrical stimulation, collagenase, cadexomer iodine, alginates, silver, foams, hydrocolloids, and cleansing and periwound care.
  • Identify product categories and their functions, and recommend cost-effective dressings.
  • Recommend adjunctive therapies such as offloading, compression, hyperbaric oxygen therapy, and support surfaces.
  • Recommend further diagnostics, including cultures, biopsy, imaging, and ankle-brachial index (ABI).
  • Make referrals to nutrition, vascular, surgical, podiatry, lymphedema, home care, or hospice services.
  • Determine steps for wound bed preparation, including debridement, infection control, and moisture management, and identify signs of infection and biofilm.

Study tip: Learn dressings by what they do (absorb, donate moisture, debride, kill bacteria) rather than by brand. Most product questions ask which category fits a wound’s exudate level and tissue type.

Re-Evaluation (16%)

Re-Evaluation asks whether your plan is working and what to change if it isn’t.

  • Evaluate treatment choices and the overall effectiveness of the treatment plan.
  • Reassess the patient’s tolerance of treatment, including pain and reactions.
  • Evaluate adherence and the barriers behind nonadherence.
  • Track healing with weekly measurements, updated risk assessments, labs, and the Pressure Ulcer Scale for Healing (PUSH) tool.
  • Describe the phases of healing: hemostasis, inflammation, proliferation, and maturation.

What questions look like: A wound has not decreased in size after several weeks of appropriate care. The best answer usually involves reassessing for an underlying cause (infection, poor perfusion, unrelieved pressure, nutrition) rather than simply switching to a new dressing.

Risk and Prevention (12%)

This domain focuses on keeping skin intact in the first place.

  • Identify risks for impaired skin integrity, including medical devices, medications, and support surfaces.
  • Use risk assessment findings (such as Braden subscale scores) to choose preventive measures like moisture barriers, prophylactic foam dressings, repositioning, and offloading.
  • Identify indications and contraindications for products, including allergies, pain, cost, and availability.
  • Identify at-risk populations and appropriate interventions.

Study tip: Don’t just memorize the total Braden score. Match each low subscale (moisture, mobility, nutrition, friction and shear) to a specific intervention.

Education (7%)

Education covers teaching patients, families, and the interprofessional team. Key objectives include using written instructions, demonstration, and return demonstration, and assessing health literacy, including reading level, language, and cognition. Questions often ask for the best way to confirm understanding, and return demonstration is frequently the answer.

Administration (7%)

Administration reflects the wound care clinician’s program-level role. It includes making evidence-based protocol recommendations, working within a facility’s formulary and policies, developing educational materials, collecting and analyzing prevalence and incidence data, and collaborating with insurers, case managers, and other facilities. Know the difference between prevalence (all existing cases at a point in time) and incidence (new cases over a period).

Legal (6%)

The smallest domain still carries real weight. It covers documenting wound characteristics and the treatment plan (location, measurements, undermining, tunneling, wound bed, edges, drainage, odor, and periwound skin), identifying scope-of-practice and federal and state regulatory issues, and applying ethical concepts such as patient autonomy and palliative wound care goals.

How Should You Use the WCC Blueprint to Build a Study Plan?

Treat the 44 learning objectives as your checklist. For each one, ask yourself whether you could explain it to a colleague without notes, and mark it strong, developing, or weak.

  1. Take a baseline: Answer a mixed set of questions before you begin a full content review so you know where you actually stand.
  2. Weight your time: Put the most hours into Assessment and Treatment, but don’t skip Education, Administration, or Legal. Those three domains make up 20 scored questions.
  3. Map your misses: Tie every missed question to a specific objective (for example, 2.07 product categories or 1.02 lab interpretation) so patterns become obvious.
  4. Study across settings: The exam is multidisciplinary. If you work in acute care, spend extra time on home health, long-term care, and outpatient scenarios, and vice versa.
  5. Revisit after a delay: Return to weak objectives in mixed practice a few days later to confirm the learning stuck.
