If you’re aiming for a career in law, consulting, or even senior leadership, chances are you’ll face the Watson Glaser Test — one of the most trusted tools employers use to measure critical thinking skills. This isn’t just another aptitude test; it’s designed to see how well you can interpret information, spot hidden assumptions, make solid deductions, and separate strong arguments from weak ones.
For recruiters, the Watson Glaser is a quick way to identify candidates with sharp reasoning and sound judgement — qualities that matter in high-stakes roles. For you, that means preparation is everything.
In this guide, you’ll not only learn the test format and scoring system, but you’ll also get free Watson Glaser practice questions with answers and proven strategies to boost your performance. Think of this as your step-by-step toolkit to mastering the test — and with the right practice, turning a potential roadblock into your competitive advantage.
Watson Glaser Test Structure
The Watson Glaser Test is divided into five key sections, each designed to assess a specific critical thinking skill. The test includes a total of 40 questions, typically distributed equally with 8 questions per section. Here's how each part works:
1. Inference Section (8 questions)
Question Type: Decide whether a conclusion is true, probably true, insufficient data, probably false, or false based on a given statement.
Skill Assessed: Ability to judge the strength of evidence and assess likelihood accurately.
2. Recognition of Assumptions Section (8 questions)
Question Type: Identify whether a statement is an assumption made in a given argument.
Skill Assessed: Detecting unstated premises and recognising implicit ideas.
3. Deduction Section (8 questions)
Question Type: Determine whether a conclusion logically follows from the premises, selecting either “Conclusion Follows” or “Conclusion Does Not Follow.”
Skill Assessed: Logical reasoning and strict deductive thinking.
4. Interpretation Section (8 questions)
Question Type: Evaluate if a conclusion is supported by the information in a short passage.
Skill Assessed: Understanding and analysing written information to draw accurate conclusions.
5. Evaluation of Arguments Section (8 questions)
Question Type: Judge whether arguments are strong or weak in the context of a stated question.
Skill Assessed: Critical evaluation, relevance, and reasoning strength.
Each section challenges a different part of your reasoning process, making the Watson Glaser critical thinking test a comprehensive measure of decision-making and analytical skills.
How Is the Watson Glaser Test Scored?
The Watson Glaser Test is scored based on the number of correct answers out of 40, known as your raw score. This score is then converted into a percentile rank, which shows how well you performed compared to other test-takers.
For example:
A score of 33–34 correct answers places you in the 80th percentile, indicating a strong performance.
36–38 correct answers puts you in the 90th percentile, an excellent score.
Scoring 39–40 correct answers ranks you in the 95th–99th percentile, placing you among top performers.
A recommended benchmark score is typically 33–34 or higher to remain competitive in most recruitment settings.
Watson Glaser Test Format
There are two main formats:
Fixed form (used in Watson Glaser II)
Item-banked format (used in Watson Glaser III – where questions vary each time)
Typical test length:
30–40 minutes for most online versions
40 questions in total
The test is usually administered online, although paper versions still exist in some settings.
The Watson Glaser Test was created in 1920 by Goodwin Watson and Edward Glaser, and is published by TalentLens (part of Pearson), which works exclusively with companies rather than offering tests directly to individual users.

Following that, you’ll review a series of statements that may or may not logically follow from the passage. Your task is to evaluate each one individually and judge how strongly it is supported by the information given.
Questions: 2
Time Limit: 2 minutes
💡 Pro Tip: Stick strictly to the text - no guessing, no common sense. If the passage doesn't explicitly state or clearly imply something, mark it as Insufficient Data. Even if the statement sounds reasonable or likely, without direct or implied support in the text, it’s not safe to assume it’s true. Practice spotting the line between what’s written and what’s assumed.
Inferences Question 1 of 2
Statement:
A national transportation study found that 70% of commuters who use public transit report being satisfied with their commute, while only 45% of car commuters report the same. The study also noted that commute length was not significantly different between the two groups. Additionally, those who used public transit reported reading, listening to podcasts, or resting during their travel time.
Proposed Interferences:
People who use public transit tend to have shorter commutes than people who drive.
Inferences Question 2 of 2
Statement:
A national transportation study found that 70% of commuters who use public transit report being satisfied with their commute, while only 45% of car commuters report the same. The study also noted that commute length was not significantly different between the two groups. Additionally, those who used public transit reported reading, listening to podcasts, or resting during their travel time.
Proposed Interferences:
Non-driving commuters may enjoy their commute more because they can engage in other activities.
Free Recognition of Assumptions Sample Questions
The next section is Recognition of Assumptions. In this section, you’ll be asked to decide whether a given assumption is taken for granted in the argument. The key is to focus only on what’s implied, not what’s stated directly. Let’s look at some practice questions with pro tips to help you spot hidden assumptions more easily.
Questions: 2
Time Limit: 2 minutes
💡 Pro Tip: Don’t confuse assumptions with conclusions. An assumption is something the argument relies on but doesn’t state—it comes before the claim. A conclusion is a result that comes after. Ask yourself: “Does this belief need to be true for the statement to make sense?” If yes, the assumption is made. If not, it isn’t.
Recognition of Assumptions Question 1 of 2
Statement:
University spokesperson: “We cannot approve the new student club until we receive a clear outline of its goals and planned activities. Approvals require full transparency to ensure alignment with university policies.”
Proposed Assumption:
Student clubs that do not provide a clear outline of their goals may violate university policies.
Recognition of Assumptions Question 2 of 2
Statement:
University spokesperson: “We cannot approve the new student club until we receive a clear outline of its goals and planned activities. Approvals require full transparency to ensure alignment with university policies.”
Proposed Assumption:
The university automatically approves all clubs that have clearly stated goals.
Free Deduction Sample Questions
In this section, you’ll be asked to decide whether a conclusion logically follows from the information provided. The focus here is on strict logic—only what is necessarily true based on the given facts. Let’s go through some practice questions with pro tips to help you master this skill.
Questions: 2
Time Limit: 2 minutes
💡 Pro Tip: In Deduction, “probably” isn’t enough—go for certainty. A conclusion must follow with absolute certainty based on the text. If it’s only “likely” or “makes sense” but isn’t logically guaranteed, the correct answer is Conclusion Does Not Follow. Stick to strict logic and don’t accept any conclusion unless it’s 100% supported.
Deduction Question 1 of 2
Statement:
All certified pilots undergo medical checks before flight.
Proposed Conclusion:
Everyone who undergoes a pre-flight medical check is a certified pilot.
Deduction Question 2 of 2
Statement:
All certified pilots undergo medical checks before flight.
Proposed Conclusion:
There may be individuals who undergo pre-flight medical checks but are not allowed to operate aircraft.
Free Interpretation Sample Questions
In this section, you’ll decide whether a conclusion can be drawn from the information given - beyond a reasonable doubt. The key is to evaluate how well the conclusion fits the evidence, without needing it to be absolutely certain. Let’s explore some practice questions with pro tips to sharpen your judgment.
Questions: 2
Time Limit: 2 minutes
💡 Pro Tip: The conclusion must be true beyond a reasonable doubt - nothing less. In the Interpretation section, a conclusion doesn’t need to be absolutely certain, but it must be strongly supported by the information in the text. If you can think of a reasonable alternative explanation, the conclusion does not follow. Always ask: “Is this the only logical way to interpret the data?” If not, be cautious.
Interpretation Question 1 of 2
Statement:
Whenever I need to print a large number of documents quickly, I use the print shop near my university. On regular days, I usually print small assignments using my home printer, even though it’s a bit slower.
Proposed Conclusion:
The print shop near the university is faster than the speaker’s home printer.
Interpretation Question 2 of 2
Statement:
Whenever I need to print a large number of documents quickly, I use the print shop near my university. On regular days, I usually print small assignments using my home printer, even though it’s a bit slower.
Proposed Conclusion:
The speaker always prints assignments at home, regardless of urgency.
Free Evaluation of Arguments Sample Questions
In this section, you’ll judge whether an argument is strong or weak in relation to a given statement. Every argument should be treated as true - your task is to evaluate how relevant and important it is to the issue. Let’s go through practice questions with pro tips to help you assess arguments with confidence.
Questions: 2
Time Limit: 2 minutes
💡 Pro Tip: Treat every argument as factually true - then test its relevance. Don’t judge whether an argument sounds right - assume it’s true and ask: “Does this directly support or weaken the statement?” A strong argument is both important and relevant to the claim. If it only reflects opinions, feelings, or unrelated facts, it's a weak argument - no matter how convincing it sounds.
Evaluation of Arguments Question 1 of 2
Statement:
Should restaurants switch to QR-code menus only?
Proposed Argument
No; many older patrons lack smartphones, so the change would deter their visits.
Evaluation of Arguments Question 2 of 2
Statement:
Should restaurants switch to QR-code menus only?
Proposed Argument
Yes; servers appreciate not having to carry and sanitize physical menus between tables.

Question 1
Statement:
A national transportation study found that 70% of commuters who use public transit report being satisfied with their commute, while only 45% of car commuters report the same. The study also noted that commute length was not significantly different between the two groups. Additionally, those who used public transit reported reading, listening to podcasts, or resting during their travel time.
Proposed Interferences:
People who use public transit tend to have shorter commutes than people who drive.
YOUR ANSWER
Not answered(INCORRECT)
CORRECT ANSWER
Insufficient Data
EXPLANATION
✅ Answer: Insufficient Data
The statement specifically says that commute length was not significantly different between the two groups. So, there is no evidence to say public transit users have shorter commutes.
➡️ The conclusion cannot be confirmed or denied.
✅ Insufficient Data is the correct answer.
Question 2
Statement:
A national transportation study found that 70% of commuters who use public transit report being satisfied with their commute, while only 45% of car commuters report the same. The study also noted that commute length was not significantly different between the two groups. Additionally, those who used public transit reported reading, listening to podcasts, or resting during their travel time.
Proposed Interferences:
Non-driving commuters may enjoy their commute more because they can engage in other activities.
YOUR ANSWER
Not answered(INCORRECT)
CORRECT ANSWER
Probably True
EXPLANATION
✅ Answer: Probably True
The statement says public transit users report higher satisfaction and that they read, listen to podcasts, or rest during the commute. This suggests these activities could be a reason for higher satisfaction, though it's not definitively proven.
➡️ This is a reasonable and likely inference, but not guaranteed.
✅ So, the answer is Probably True.
Question 3
Statement:
University spokesperson: “We cannot approve the new student club until we receive a clear outline of its goals and planned activities. Approvals require full transparency to ensure alignment with university policies.”
Proposed Assumption:
Student clubs that do not provide a clear outline of their goals may violate university policies.
YOUR ANSWER
Not answered(INCORRECT)
CORRECT ANSWER
Assumption Made
EXPLANATION
✅ Answer: Assumption Made
Explanation:
The spokesperson says that without a clear outline, the club cannot be approved because transparency is needed to check for alignment with policy. This implies that lack of clarity could mean non-compliance, and thus a risk of policy violation.
✅ The reasoning hinges on this assumption, so it is made.
Question 4
Statement:
University spokesperson: “We cannot approve the new student club until we receive a clear outline of its goals and planned activities. Approvals require full transparency to ensure alignment with university policies.”
Proposed Assumption:
The university automatically approves all clubs that have clearly stated goals.
YOUR ANSWER
Not answered(INCORRECT)
CORRECT ANSWER
Assumption Not Made
EXPLANATION
✅ Answer: Assumption Not Made
Explanation:
The statement only says that a clear outline is a requirement, not that it guarantees approval. There may be other criteria involved in the decision.
❌ Assuming automatic approval goes beyond what the speaker implies.
✅ Therefore, this assumption is not made.
Question 5
Statement:
All certified pilots undergo medical checks before flight.
Proposed Conclusion:
Everyone who undergoes a pre-flight medical check is a certified pilot.
YOUR ANSWER
Not answered(INCORRECT)
CORRECT ANSWER
Conclusion Does Not Follow
EXPLANATION
✅ Correct Answer: Conclusion Does Not Follow
Explanation:
The statement tells us only that certified pilots undergo pre-flight checks — not that only pilots do so. It’s possible others undergo the checks too (e.g., trainees, co-pilots, flight engineers).
So, saying that everyone who undergoes the check is a pilot overgeneralizes and cannot be logically concluded.
➡️ Conclusion Does Not Follow.
Question 6
Statement:
All certified pilots undergo medical checks before flight.
Proposed Conclusion:
There may be individuals who undergo pre-flight medical checks but are not allowed to operate aircraft.
YOUR ANSWER
Not answered(INCORRECT)
CORRECT ANSWER
Conclusion Follows
EXPLANATION
✅ Correct Answer: Conclusion Follows
The statement tells us about certified pilots, but it says nothing about who else might undergo medical checks.
The proposed conclusion says - **"There may be individuals who undergo pre-flight medical checks but are not allowed to operate aircraft." **
This conclusion suggests that some people who are not certified pilots (and therefore not permitted to operate aircraft) might still undergo medical checks — for example, trainees or flight applicants.
➡️ Since the original statement only speaks about pilots, and does not claim that only certified pilots undergo the checks, it allows for the possibility that others do as well. That makes the conclusion logically possible and consistent with the statement.
Question 7
Statement:
Whenever I need to print a large number of documents quickly, I use the print shop near my university. On regular days, I usually print small assignments using my home printer, even though it’s a bit slower.
Proposed Conclusion:
The print shop near the university is faster than the speaker’s home printer.
YOUR ANSWER
Not answered(INCORRECT)
CORRECT ANSWER
Conclusion Follows
EXPLANATION
✅ Answer: Conclusion Follows
Explanation:
The speaker says they use the print shop when they need to print a large number of documents quickly and use the slower home printer on regular days.
➡️ This clearly implies that the print shop is faster.
✅ While it's not explicitly stated, the logic behind the speaker's choice makes this conclusion highly probable, and it follows beyond reasonable doubt.
Question 8
Statement:
Whenever I need to print a large number of documents quickly, I use the print shop near my university. On regular days, I usually print small assignments using my home printer, even though it’s a bit slower.
Proposed Conclusion:
The speaker always prints assignments at home, regardless of urgency.
YOUR ANSWER
Not answered(INCORRECT)
CORRECT ANSWER
Conclusion Does Not Follow
EXPLANATION
✅ Answer: Conclusion Does Not Follow
Explanation:
The passage says the speaker prints small assignments at home on regular days, but when speed is important, they use the print shop.
❌ So, it's not true that they always use the home printer.
✅ The conclusion contradicts the speaker’s described behaviour and does not follow.
Question 9
Statement:
Should restaurants switch to QR-code menus only?
Proposed Argument
No; many older patrons lack smartphones, so the change would deter their visits.
YOUR ANSWER
Not answered(INCORRECT)
CORRECT ANSWER
Strong Argument
EXPLANATION
✅ Answer: Strong Argument
Explanation:
➡️ This argument directly tackles the core business concern of the proposal - whether switching to QR-code menus will harm customer visits - by identifying a substantial demographic (older patrons) who cannot access digital menus. Since it highlights a clearly relevant and potentially significant drop in foot traffic and revenue, it meets both the relevance and importance criteria for a strong argument.
Question 10
Statement:
Should restaurants switch to QR-code menus only?
Proposed Argument
Yes; servers appreciate not having to carry and sanitize physical menus between tables.
YOUR ANSWER
Not answered(INCORRECT)
CORRECT ANSWER
Weak Argument
EXPLANATION
✅ Answer: Weak Argument
Explanation:
➡️ While reduced sanitization chores benefit staff, this focus on backend convenience does not address whether patrons—especially those without smartphones—can view the menu. Because it centers on an operational perk rather than customer access or satisfaction, the argument is only tangentially related to the proposal’s primary concern and is therefore weak.
Tips for Passing the Watson Glaser Test Using the RED Model
Recognize Assumptions: Question Everything
Don’t accept statements at face value - ask yourself what’s being taken for granted.
Look for gaps in logic or evidence, and identify what must be true for a statement to hold.
Practice distinguishing between what is stated and what is merely implied.
Evaluate Arguments: Focus on Relevance and Logic
A strong argument directly supports the conclusion and is relevant to the issue at hand.
Avoid being swayed by emotional or persuasive language—evaluate only the logic.
When reviewing practice questions, ask: “Is this argument important and directly related?”
Draw Conclusions: Be Evidence-Led
Base your conclusions solely on the information provided—do not add outside knowledge.
Eliminate options that go beyond the evidence, make generalisations, or jump to conclusions.
Stay flexible: good thinkers revise their conclusion if new facts justify it.
Practise Each RED Skill Separately
Use targeted practice sessions to strengthen one RED skill at a time.
Review errors by categorising them under assumptions, argument evaluation, or conclusion errors.
Think Like a Judge, Not a Debater
Your role is not to argue or persuade but to assess whether reasoning is logically sound.
Stay objective, detach from opinions, and focus only on critical analysis.
These RED-based tips align with how the Watson and Glaser practice test evaluates thinking. Mastering these three areas is the fastest route to scoring high—especially when practising with a free Watson Glaser practice test with answers. Let me know if you'd like these tips as a visual checklist or worksheet.
