Let’s break down everything you need to know.

What Is the Structure of the LMSW Exam?

The LMSW exam is delivered entirely through computer-based testing and follows a very specific structure used across the ASWB Master’s-level licensure exam.

Below is the complete overview:

📌 Total Number of Questions

The exam includes:

• 170 total multiple-choice questions
  
• 150 scored questions
  
• 20 unscored pretest questions
  

While 150 questions determine your score, the 20 unscored items are mixed randomly throughout the exam. You won’t know which questions they are—which means you must give equal effort to every single item.

📌 Question Format

Every question is:

• Multiple-choice
  
• Has 4 answer options
  
• Has only 1 correct answer
  

Questions vary in difficulty and complexity. Expect:

• Straightforward knowledge questions
  
• Scenario-based ethical dilemmas
  
• “First,” “Next,” or “Best” questions requiring prioritization
  
• Questions with subtle distinctions between answer choices
  

Why the ASWB Uses Pretest Questions

The 20 unscored questions are experimental items used by ASWB to test difficulty, clarity, and fairness for future exam versions. These do not affect your score and cannot be identified.

Because of this, it’s crucial to:

✔️ Stay consistent
✔️ Avoid guessing based on “vibes”
✔️ Treat every question as if it counts

Consistency is key to maintaining accuracy and stamina across the entire 170-question exam.

Exam Length: How Long Is the LMSW Exam?

The exam gives you 4 hours of total seat time.

That time includes:

• Reading the questions
  
• Answering each item
  
• Marking and reviewing
  
• Taking breaks (optional—but the clock keeps running)
  

If you finish early, you can end the exam early. But most people use most or all of the allotted time.

Time Per Question Breakdown

With 4 hours (240 minutes) for 170 questions, you have approximately:

⏱️ 1 minute and 20 seconds per question

On paper, that might feel generous.

In reality:

• Scenario-based questions take longer
  
• Ethics dilemmas require careful reading
  
• Fatigue builds around the 2.5 to 3-hour mark
  
• Reviewing flagged items takes extra time
  

This is why practicing with full-length timed mock exams matters so much.

What the Testing Environment Is Like

All LMSW exams are taken at Pearson VUE testing centers unless your state allows online testing (most still require in-person).

Here’s what you can expect inside the testing center:

1. Secure Check-In

You’ll present valid ID, store personal belongings, and complete a security process that may include:

• Locker assignment
  
• Metal detection (varies by location)
  
• Signature or palm scan
  
• Photo capture
  

Pearson VUE takes exam security seriously.

2. Individual Testing Station

You’ll be directed to a small cubicle with:

• Desktop computer
  
• Noise-reducing headphones
  
• Scratch paper and pencil
  
• On-screen timer
  
• “Flag for review” marking tool
  

The environment is quiet, structured, and standardized.

3. On-Screen Tools

Your testing interface includes:

• A highlight tool
  
• A strike-through tool for eliminating answer choices
  
• A flag button to revisit questions later
  
• A review screen at the end
  
• A timer (always visible)
  

Question Types You’ll See on the Exam

The LMSW exam uses a mixture of question types that reflect real-world decision-making.

Here’s what to expect:

1. Knowledge-Based Questions

These involve:

• Definitions
  
• Theories
  
• Models
  
• Concepts
  
• Ethical terms
  

These are the easiest questions on the exam.

2. Scenario-Based Questions

These test your ability to:

• Interpret client situations
  
• Assess immediate needs
  
• Use ethical judgment
  
• Apply practice principles
  

Expect long paragraphs, multiple client details, and subtle clues.

3. Priority Questions (“FIRST,” “NEXT,” “BEST”)

These are the trickiest items on the LMSW exam and require strong understanding of:

• Safety
  
• A social worker’s role
  
• Ethical obligations
  
• Client self-determination
  
• Scope of practice
  
• Cultural competence
  

Knowing the proper sequence of actions is essential for passing the exam.

Pacing Strategy: How to Manage the 4 Hours Effectively

Time management is one of the top reasons people pass—or fail—the exam.

Here’s a recommended pacing plan:

Phase 1: First 60 Questions (First Hour)

Goal: Warm up, go steady, build momentum

This portion will feel easier. Don’t overthink.

Phase 2: Middle 70 Questions (Hours 1–3)

Goal: Stay focused, stick to your pace

This is where mental fatigue starts.
Stay consistent and avoid spiraling into overthinking.

Phase 3: Final 40 Questions (Last Hour)

Goal: Re-read carefully, eliminate distractors

Your brain will be exhausted.
The last 40 questions often make or break your score.

Review Time

Try to leave yourself at least 10–15 minutes to revisit flagged questions.

How the Timer Affects Your Exam Strategy

Because the timer is always visible:

• Some people find it motivating
  
• Others find it stressful
  

Try practicing with timers during mock exams so you’re desensitized by the real thing.

Why Mock Exams Are Essential

Timed mock exams help you:

✔️ Build endurance
✔️ Strengthen pacing
✔️ Recognize question patterns
✔️ Reduce anxiety
✔️ Mimic the real test experience

Aim to complete at least:

Two full-length, 170-question LMSW mock exams

This single step raises pass rates significantly.

Pro Study Tip

Simulate the real test environment when practicing:

• Set a 4-hour timer
  
• Sit at a desk
  
• No phone
  
• No notes
  
• No breaks unless absolutely necessary
  

You train your brain to stay focused for the full duration.

What Happens After You Finish the Exam?

When the last second runs out or you submit the exam early:

• Your screen immediately shows PASS or FAIL
  
• You’ll receive a printed score report
  
• The report includes performance by content domain
  
• You can use this for retake planning (if needed)
  

No waiting days or weeks.
