What is the NCLEX? — Complete Guide for Nurses (2026)

What is the NCLEX?

The NCLEX (National Council Licensure Examination) is the standardized exam that all nursing graduates must pass to obtain their nursing license in the United States and Canada. There are two versions:

• NCLEX-RN: For Registered Nurse licensure (after ADN, BSN, or diploma program)
• NCLEX-PN: For Licensed Practical Nurse / Licensed Vocational Nurse licensure (after LPN/LVN program)

The exam is developed and administered by the National Council of State Boards of Nursing (NCSBN) and delivered at Pearson VUE testing centers nationwide.

What Does NCLEX Stand For?

NCLEX stands for National Council Licensure Examination. It's the standardized test that determines whether a nursing graduate is safe and competent to practice nursing at the entry level.

Why Does the NCLEX Matter?

• Legal requirement: You cannot legally practice nursing without passing the NCLEX
• Standardized measure: Ensures all nurses meet a minimum competency standard
• National recognition: Passing the NCLEX is recognized in all 50 states
• Patient safety: The exam tests clinical judgment and critical thinking — essential for safe patient care

NCLEX Exam Format

The NCLEX uses Computerized Adaptive Testing (CAT), which means the test adapts its difficulty based on your responses:

• If you answer correctly, the next question gets harder
• If you answer incorrectly, the next question gets easier
• The computer continuously estimates your ability level until it reaches 95% confidence

Question Count

• Minimum: 75 questions (NCLEX-RN) / 85 questions (NCLEX-PN)
• Maximum: 145 questions (NCLEX-RN) / 205 questions (NCLEX-PN)
• Time limit: 5 hours maximum

Question Types

• Multiple choice: Traditional 4-option questions (most common)
• Select all that apply (SATA): Multiple correct answers
• Fill in the blank: Calculate a numerical answer
• Ordered response: Drag items into correct order
• Hot spot: Click on the correct area of an image
• Audio/video: Listen to or watch a clinical scenario

NCLEX Scoring — Pass or Fail

The NCLEX is a pass/fail exam — there is no numerical score. The CAT algorithm determines with 95% confidence whether you are above or below the passing standard.

How the Computer Decides Pass/Fail

1. After each question, the computer re-estimates your ability level
2. It compares your estimated ability to the passing standard (logit)
3. When it reaches 95% confidence that you're above OR below the standard, the test stops
4. If you run out of questions (145/205) or time (5 hours), your last ability estimate determines the result

Does Getting Fewer Questions Mean You Passed?

Not necessarily. The test can stop at the minimum (75) if you clearly passed OR clearly failed. However, statistically, candidates who pass at 75 questions are significantly more likely to have passed than failed. Getting the maximum questions means the computer struggled to determine your ability — you were very close to the passing standard.
