What are the five Watson Glaser test sections?

The Watson Glaser Critical Thinking Appraisal is usually built around five core reasoning skills. Each section tests a different part of objective, evidence-based thinking.

Watson Glaser sectionWhat it testsBest test tip
InferencesJudging whether a conclusion is true, probably true, false, probably false or unsupported.Separate what is proven from what merely sounds plausible.
Recognition of AssumptionsSpotting unstated assumptions behind an argument or claim.Ask: must this be accepted for the statement to make sense?
DeductionsDeciding whether a conclusion follows necessarily from the information given.Ignore real-world knowledge and use only the stated facts.
InterpretationAssessing whether a conclusion follows beyond reasonable doubt from the evidence.Look for overclaiming, exaggeration or missing evidence.
Evaluation of ArgumentsDistinguishing strong, relevant arguments from weak or irrelevant ones.Focus on relevance, importance and directness.

Passing Watson Glaser Test section-by-section

The Watson Glaser test is the most widely used critical thinking test in the world. There are five Watson Glaser sections. We go through introducing and sharing the instructions for each of these five ‘Watson Glaser subtests’ below:

You therefore need to reflect upon the following two key Watson Glaser critical reasoning skills:

2) Passing Watson Glaser Recognition of Assumptions question type

Let’s start with the key learning point, what is an assumption?

An assumption is something presupposed or taken for granted. When you say, ‘I’ll be a qualified solicitor in two months’, you take it for granted that you will be alive in two months, that you will pass the relevant examinations, and similar things.

Remember to judge each assumption independently. 

3) Passing Watson Glaser Test’s Deduction section 

4) Passing the Watson Glaser Interpretation questions

5) Passing Watson Glaser Evaluation of Arguments section 
Why does the Watson Glaser Test have a Evaluation of Arguments section?

In making decisions about important questions, it is desirable to be able to distinguish between arguments that are strong and arguments that are weak, as far as the question at issue is concerned.

What skills do critical thinking tests like the Watson Glaser Test require?

The following skills contribute to effective critical thinking:

How does the Watson Glaser assess critical thinking?

The Watson Glaser test assesses critical thinking skills via:

No prior knowledge is required since the Watson Glaser relies on existing knowledge being ‘igored’. The respondent can only use the evidence presented verbally in each Watson Glaser question.

When is the Watson Glaser used?

When you are applying for a

As long as critical thinking is a prerequisite skill to do that role effectively.

What is the format of a Watson Glaser test?

The Watson Glaser test is a timed, multiple-choice assessment, the most recent version of which consists of 40 questions with a 30-minute time constraint.

There are the following five sections in the Watson Glaser:

Drawing inferences

You’ll need to critically analyse the information in the given paragraph to determine if these statements are true, probably true, false, probably false, or if there is insufficient proof to determine either way.

Recognising assumptions

Assumptions relate to what we understand to be true without needing solid proof. They are the underlying facts that give an argument its validity.

If the statement relies on the assumption being true, you would mark it as ‘assumption made’.

If the assumption is irrelevant to the statement, or bears no weight on its validity, you would mark it as ‘assumption not made’.

Deduction

Deductive reasoning is the act of arriving at a fact-based conclusion through a logical thought process. A deduction differs from an assumption in that it is what we take away from an argument, as opposed to the facts on which an argument needs to stand.

Based solely on the evidence presented in a statement or short paragraph, you’ll need to determine if a list of conclusions do or do not logically follow on from the information in front of you.

Interpreting

Evaluating arguments

This last section looks at your ability to separate a weak argument from a strong one. You’ll need to decide if an argument is relevant and challenging, and therefore strong, or vague and unrealistic, and therefore weak.

What skills does it look to measure?

The five sections combined give an overall picture of your performance in key areas, and measure your ability to:

Watson Glaser Test practice

What is a pass score on the Watson Glaser tests?

It is therefore difficult to state an exact pass score on the test, since it depends entirely on the performance of your peers. Ideally, you’d look to reach 75% and above to give yourself a competitive edge.

Which professions use Watson Glaser tests, and why?

Watson Glaser test usage is most common in the legal and professional services sectors. In other words, the law, banking and financial sectors. In many such roles executives must regularly take nformed business decisions. Each decison must be rooted in fact. As well as being objectively free from any biased thinking.

How should I prepare for the Watson Glaser?

Recognising assumptions. Instead of simply taking things at face value, such as the news or a part of a conversation with a friend or co-worker, ask yourself if what you’re hearing can actually be classified as true, and what the facts are that back it up. Are they evidential, or based on assumptions?

Evaluating arguments. We’re all guilty of seeking out information that confirms our own perspective. Instead, actively look for opinions that contradict your own and assess them from an objective point of view. The better you become at seeing both sides of a story, the more prepared you’ll be to critically evaluate arguments in your Watson Glaser test.

Drawing conclusions. These conclusions may not align with your own perspective, but a Watson Glaser test requires that you conclude impartially – and as with most things in life, practice makes perfect here.

Watson Glaser tips

Study the practice questions

Watson Glaser Test practice

Look for keywords and phrases

The statement, proposition or paragraph of text at the start of each question will inevitably include keywords or phrases that relate directly to the assumptions, inferences or conclusions given. These are your clues. Identify them, and you’ll find it much easier to analyse each scenario objectively.

Split your time evenly

Remember, you have a set amount of time to work through all five sections of the test. Split this evenly across the board before you start, and keep track of how much time you spend on each question. It may seem counterintuitive to add to the pressure, but in setting yourself a time frame, you eliminate the risk of dedicated excessive attention to any one part of the test.


Who uses the Watson Glaser test?

The test is quite popular among law firms or audit firms that analyze the true potential of a professional.

Also, the banking industry’s hiring departments use the Watson Glaser test to

The Watson Glaser assessment is also important for recruiting junior and senior partners in a law firm and has been proved effective in some of the most recognized companies in the world.

Why use the Watson Glaser test?

What is critical thinking?

Critical thinking is about logic and applying rationale to every argument that one might have with themselves. In today’s world, there are so many distractions, so it is even more important for identifying the critical thinking skill level of an individual. A critical thinker can easily analyze whether some information being provided to them is true to the core or not.

Watson Glaser Practice Test – Set A (Guided Coaching)

This Watson Glaser practice test Set A is designed to help you learn how to answer each question type correctly. Each answer includes a coached explanation, showing you how a high-scoring candidate reasons under exam conditions.

How to use this page: Attempt each question first. Only read the explanation after committing to an answer.


Deduction – Set A

In Deduction questions, your task is to decide whether the conclusion follows with certainty from the statements. Ignore real-world plausibility and focus only on logic.

Deduction A1 (Easy)

Some appeals are heard in private.
All hearings held in private exclude the public.

Conclusion: Some appeals exclude the public.

Answer: YES

Coaching explanation: Start by mapping the groups carefully. Some appeals fall into the group of private hearings, and all private hearings exclude the public. That means at least some appeals must exclude the public. When “some” items fall inside a group with a definite property, that property must apply to them.

Deduction A2 (Easy–Medium)

All cases involving national security are closed hearings.
Some tribunal cases involve national security.

Conclusion: Some tribunal cases are closed hearings.

Answer: YES

Coaching explanation: Work step by step through the chain. Some tribunal cases involve national security, and all such cases are closed hearings. Any tribunal case involving national security must therefore be closed. The conclusion simply restates that unavoidable result.

Deduction A3 (Medium)

All senior managers approve budgets.
Some employees approve budgets.

Conclusion: Some employees are senior managers.

Answer: NO

Coaching explanation: Be careful not to reverse the logic. You are told that all senior managers approve budgets, but that does not mean everyone who approves budgets is a senior manager. Budget approval could be delegated or shared. Because that possibility exists, the conclusion does not follow.


Inference – Set A

Inference questions test what is definitely true, probably true, insufficient data, probably false, or false based only on the statement.

Inference A1 (Easy)

A court introduced compulsory training on courtroom procedure for new clerks.

Inference: Some clerks were unfamiliar with courtroom procedure.

Answer: PROBABLY TRUE

Coaching explanation: Ask what most likely explains the action described. Introducing compulsory training usually reflects a belief that knowledge gaps exist, even if that belief is not explicitly stated. However, training could also be precautionary. That’s why the inference is reasonable but not certain.

Inference A2 (Easy–Medium)

A law firm installed secure access controls for client files.

Inference: Client confidentiality had previously been breached.

Answer: PROBABLY FALSE

Coaching explanation: Avoid assuming a problem just because a safeguard exists. Secure access controls are often implemented to prevent breaches, not because breaches have already occurred. While it is possible there was a past issue, the statement makes that explanation unlikely.

Inference A3 (Medium)

A company scheduled all performance reviews during working hours.

Inference: Management wanted to avoid staff using personal time.

Answer: PROBABLY TRUE

Coaching explanation: Think about typical managerial motives. Scheduling reviews during working hours strongly suggests concern about fairness and work-life balance. That motive is plausible but not guaranteed, since other explanations exist. This places the inference in the “probably true” category.


Recognition of Assumptions – Set A

Your task is to decide whether the assumption must be true for the statement to make sense.

Assumptions A1 (Easy)

A court introduced remote hearings to reduce delays.

Assumption: Remote hearings reduce delays.

Answer: ASSUMPTION MADE

Coaching explanation: Ask whether the decision would still make sense without the assumption. Introducing remote hearings to reduce delays only works if remote hearings actually reduce delays. Without that belief, the policy lacks justification.

Assumptions A2 (Medium)

A regulator required written reasons for licensing refusals.

Assumption: Written reasons improve transparency or accountability.

Answer: ASSUMPTION MADE

Coaching explanation: Written reasons serve a purpose. Requiring them implies a belief that transparency or accountability improves as a result. Without that belief, the requirement would make little sense.

Assumptions A3 (Medium–Hard)

A firm centralised approval for major expenditures.

Assumption: Decentralised approval leads to inconsistency or risk.

Answer: ASSUMPTION MADE

Coaching explanation: Centralising approvals only makes sense if decentralisation is seen as problematic. The decision depends on the belief that decentralised approval increases risk or inconsistency. Without that belief, the change would be unnecessary.


Evaluation of Arguments – Set A

Strong arguments are relevant and weighty. Weak arguments are off-topic, superficial, or based on preference.

Evaluation A1 (Medium)

Should courts publish sentencing guidelines?

Argument: Yes, because guidelines promote consistency in sentencing.

Answer: STRONG

Coaching explanation: Consistency is a central concern in justice systems. Publishing guidelines directly addresses that concern. Because the argument connects clearly to the policy question, it is strong.

Evaluation A2 (Easy)

Should juries be required to give reasons for verdicts?

Argument: No, because this would increase trial duration.

Answer: WEAK

Coaching explanation: Trial length is a secondary issue. The question concerns fairness, transparency, and accountability. Simply saying something takes longer does not engage with those core issues, making the argument weak.

Evaluation A3 (Medium–Hard)

Should companies monitor employee emails?

Argument: Yes, because monitoring can prevent legal liability.

Answer: STRONG

Coaching explanation: Preventing legal liability is a serious organisational concern. Monitoring emails directly relates to compliance and risk management. The argument is relevant and weighty, so it is strong.


Interpretation – Set A

Decide whether the conclusion follows beyond reasonable doubt from the passage.

Interpretation A1 (Easy)

A report found that many appeals were dismissed procedurally, while fewer were dismissed after substantive review.

Conclusion: Most appeals are dismissed after substantive review.

Answer: NO

Coaching explanation: Compare the quantities carefully. The passage says procedural dismissals are more common. The conclusion reverses that relationship, so it does not follow.

Interpretation A2 (Easy)

Most cases listed for trial settled before the hearing, while fewer proceeded to judgment.

Conclusion: Settlement is more common than judgment.

Answer: YES

Coaching explanation: This is a direct comparison. Settlements occurred more frequently than judgments. The conclusion accurately reflects the information given.

Interpretation A3 (Medium)

Many employees completed mandatory training, while fewer attended optional courses.

Conclusion: Optional courses attracted fewer participants.

Answer: YES

Coaching explanation: The passage explicitly compares participation levels. Optional courses had fewer attendees than mandatory ones. The conclusion follows directly.

Watson Glaser Test Tips FAQs

What is the best way to prepare for the Watson Glaser test?

The best preparation is to practise each Watson Glaser section separately before moving on to full timed tests. Focus on understanding why answers are correct, not just whether you got them right.

Is the Watson Glaser test hard?

The Watson Glaser test can be difficult because the wrong answers are often plausible. The main challenge is staying objective and basing every answer only on the information provided.

What skills does the Watson Glaser test measure?

It measures critical thinking skills, including inference, deduction, assumption recognition, interpretation of evidence and evaluation of arguments.

How can I improve my Watson Glaser score quickly?

Practise under timed conditions, review your errors by question type, and learn to identify common traps such as overclaiming, unsupported assumptions and using outside knowledge.

Should I use outside knowledge in the Watson Glaser test?

No. Watson Glaser answers should be based only on the information in the passage or statement. Outside knowledge, personal opinion and assumptions can easily lead to incorrect answers.
