What is Watson Glaser Test and How to Get A High Score?

As suggested by its name, the Watson Glaser Critical Thinking Appraisal is a critical thinking test. While there are additional types of critical thinking tests out there, Watson Glaser is by far the most common one.

It is usually used by law firms and other organisations to assess and screen candidates during the recruitment process. The skills evaluated are crucial for succeeding in both the legal world and managerial roles.

These are the top five firms that use the Watson Glaser Critical Thinking Appraisal in their recruitment process:

  • Clifford Chance – A distinct and important member of the “Magic Circle.” In 2020 Clifford Changed was named “International Law Firm of the Year,” and ranked among the world's top 10 multinational law firms.
  • Linklaters – Another “Magic Circle” member, Linklaters is one of England’s top three law firms, employing over 3,000 lawyers across 20 countries.
  • Dentons – This relatively young firm grew to be the 5th largest law firm by revenue, the largest by lawyers and operates in 190 offices across seven countries.
  • Hogan Lovells – An American-British international law firm, holds the title as the 11th largest law firm in the world.
  • GLS – The British Government Legal Service employs lawyers who provide legal advice to the government and represent it in court.

The Watson Glaser test measures these candidate’s critical thinking skills:

  1. Critical thinking.
  2. Analysing and interpreting arguments.
  3. Making deductions and draw conclusions.
  4. Assessing the strength of an argument.
  5. Recognising and understanding assumptions.


These traits are measured by 40 questions and divided into five sections. Each section assess a different critical thinking ability or skill.

In accordance with the abilities this aptitude test assesses, all questions revolve around verbal information, that you will have to analyse, interpret and use to draw conclusions. All questions are in multiple-choice answers format.

It will take you around 30 minutes to complete the test. Each section is timed separately, and the time limit is quite stressful. Especially when dealing with a long and confusing text.

Like all tests, the absolute best way to get a high score is by practising.
But as the Watson Glaser test is unique, just practising is not enough. It has to be an ACCURATE practice.

Only by using accurate Watson Glaser practice tests, which simulate the real test, will you be familiar with the different sections and rules. This intimate familiarity is your key to gaining the advantage over your competition.

How is the Watson Glaser Test Scored?

Your score on the Watson Glaser test is represented as your relative position compared to a norm group.

Your potential employer will compare the profiles of all probable candidates. Those with the highest relative scores will pass the test and move on to the next stage.

So, beating the Watson Glaser is not enough, since you will also have to beat the other competitors.

What is considered to be a good score is dependent on the firm you are applying for. Ideally, you would want to score at least 80% to be considered for the position.

Before we dive in the Watson Glaser critical thinking test format, we first have to understand what a critical thinking test is.

What is a Critical Thinking Test?

A critical thinking test, sometimes referred to as critical reasoning test, is an aptitude test that measures your ability to assess a situation through various perspectives. While taking the test, you will be asked to acknowledge, extract, and interpret facts, opinions, and assumptions.

The critical thinking tests are usually used in the legal professions’ recruitment process, where a major critical thinking ability needed is to make a strong, solid argument. Additional skills measured are being able to analyse verbal information, make accurate assumptions and draw conclusions.

The critical reasoning test measures these critical thinking skills by using paragraphs of text, some short and some very long. Your job is to analyse the text in different ways and show that you understood every aspect of it.

Now that we understand the general purpose of a critical thinking test, and what critical thinking ability it is set out to measure, let’s see how the Watson Glaser Test achieves just that.

What is the Watson Glaser Critical Thinking Test Format?

The Watson Glaser Test includes 40 multiple-choice questions, that takes 30 minutes to answer.

The test is divided to five sections:

  1. Inference assessment
  2. Recognising assumptions
  3. Deduction
  4. Interpretation
  5. Evaluation of arguments


Each section is unique and has a set of rules you need to familiarise yourself with. Read on to learn about each section and get Watson Glaser sample questions.

To boost your Watson Glaser score, you have to master the test's unique format and sections. To do that you have to practise.

Watson Glaser Practice Test Sample Questions & Sections Overview

Inference Assessment Overview

The Inference Assessment section, will present you with a single statement of facts that you regard as true.

Every statement will be followed with a series of inferences – conclusions that one might draw from the facts in the statement.

Your task is to examine the inferences, and decide how true or false each one is, on a scale:

  • True
  • Probably True
  • Insufficient Data
  • Probably False
  • False

Note: Sometimes, in deciding whether an inference is probably true or false, you will have to use common knowledge or information.

While you should not hesitate to use such knowledge, it is unadvisable to rely on such knowledge as the sole basis for judging an inference to be True or False. These rulings must be supported by the statement of facts given.

Inference Assessment Sample Question

Statement: James is a human rights activist who was fined £60 on three different days during the past month for smoking in public at his workplace. On each of the occasions, he admitted to the act peacefully, telling policemen that he is unwilling to conform with such a breach of people's right to privacy. James paid the three fines shortly after receiving them.

Inference: James has spent at least a couple hundreds of pounds in his struggle to oppose violation of civil liberties this year.

  • True
  • Probably True
  • Insufficient Data
  • Probably False
  • False
Answer and Explanation

The correct answer is 'Probably True.'

You know that James had paid 180 pounds in the past month alone. You also know he is a human rights activist who is willing to spend money for his cause, based on his actions and testimony.

As such, even though it is not explicitly mentioned in the text, it is safe to assume that sometime in the year James had spent at least 20 more pounds on his activism, smoking-related or otherwise.

Recognising Assumptions Overview

In the Watson Glaser Test Recognising Assumptions section, you will be presented with different statements. Several proposed assumptions follow each statement. Your job is to decide for each assumption whether a person, in making the given statement, is really making that assumption – that is, taking it for granted, justifiably or not.

Note: These assumptions do not have to concur with reality or reason – you are not judging their common sense, but plainly whether they are made or not.

Recognising Assumptions Sample Question

Statement: Complaints were raised against the town's sole French teacher for using her monopoly to charge more than her late predecessor. In fact, however, she does not earn more money on each lesson than she would have before, because she lives out of town and her fee reflects higher transportation costs than those of her predecessor, who lived in town.

Proposed Assumption: Service providers who spend more on transportation are more expensive.

  • Assumption Made
  • Assumption Not Made
Answer and Explanation

Assumption is not made.

This is a generalisation of what happened in the town. This statement is a logical rule—it refers to all service providers in the world.

The author might think this is true, but he doesn't have to assume it in order for the passage to make sense. Therefore, it is not assumed.

Deduction Overview

In the Deduction section, you will have to read several passages. Each one will be followed by a suggested conclusion.

Your task is to determine whether the conclusion “follows” or “does not follow” the information presented in the text.

Note: While making a decision, you should rely only on the premises, even though you may believe some conclusions may or may not be true according to your general knowledge.

For the purposes of this test, consider the premises in each exercise to be true without exception. (e.g., the sentence "apples are tasty", should be read as all apples are actually tasty, even rotten apples and unripe apples).

Deduction Sample Question

Statement: Some citizens pay taxes. Many citizens receive income support.

Conclusion: More citizens receive income support than citizens who pay taxes.

  • Conclusion follows
  • Conclusion does not follow
Answer and Explanation

Conclusion does not follow.

Citizens = A, pay taxes = B, receive income support = C.
According to the premises, (A+B)some, and (A+C)many.

The conclusion states (A+C) > (A+B).

Some refer to a portion - a quantity between 1 to everything, while many others refer to multiplicity – at least 2 and up to everything.
However, you have no grounds to infer an accurate quantity of either statement; therefore, the conclusion does not necessarily follow.

In other words:

This one is tricky. Although there is a hierarchy between words that indicate a quantity, and “many” is more than “some”, that is only true when discussing the same group.

For example, if the conclusion was “there are some citizens who receive income support”, it would follow, because you can infer “some” from “many”. However, you cannot compare the quantities of two different groups this way.

Interpretation Overview

The Watson Glaser Test Interpretation section is similar to the Deduction section we just talked about.

In this section you will be presented with a short paragraph, for which you have to assume that everything stated in it is true. Then, you will have to decide if a certain conclusion is followed beyond a reasonable doubt from the text, or not.

Note: While section 3 (Deduction) instructions ask us to decide whether a proposed conclusion “necessarily follows”, section 4 (Interpretation) offers a disjunction: The proposed conclusion can necessarily follow or probably follow (beyond a reasonable doubt).

Another distinction is that section 3 mainly uses formal logic, whereas section 4 is less formal in that way.

Interpretation Sample Question

Text: In the years 2011-12, 32% of pupils entitled to free school meals (an indicator of low socioeconomic status) achieved five GCSE passes at grade C or above. This is compared to 65% of pupils who were not entitled to free school meals.

Conclusion: Most of the pupils who were not entitled to a free school meal achieved five GCSE passes at grade C or above.

  • Conclusion follows
  • Conclusion does not follow
Answer and Explanation

Conclusion follows.

The logic behind this answer is mathematical: the passage states that 65% of the pupils who were not entitled to a free school meal achieved five GCSE passes at a minimum of a C grade. Since 65% is greater than 50%, we can conclude that they are the majority.

Evaluation of Arguments Overview

In this final Watson Glaser test section, you will be presented with a question or a topic, followed by several arguments you need to evaluate. For each argument, you will have to determine whether it is “strong” or “weak”.

Note: For an argument to be strong, it must be both important and directly related to the question. An argument is weak if it is not directly related to the question (even though it may be of great general importance), if it is of minor importance, or if it is only related to trivial aspects of the question.

Evaluation of Arguments Sample Question

Question: Should parents put their children in preparation courses for gifted tests, in order for them to reach their full potential?

Argument: Yes; parents are responsible for their children’s future and should do whatever they can to help them succeed in life.

  • Strong argument
  • Weak argument
Answer and Explanation

Weak argument.

This argument, although of great general importance, is not directly related to the question. The question specifically asked about preparation courses for gifted tests, and the arguments do not even mention them.

If, for example, the argument made the connection between preparation courses and success, the argument would have been strong. Since it does not, it is weak.

  1. Accuracy - you will get Watson Glaser practice questions that EXACTLY simulate the real test, sections, and format.

Watson Glaser Critical Appraisal Test Tips

  1. Take the example questions if offered. Sometimes you will be offered example questions on your test day before your actual test. If this happens, treat it as an opportunity to get confident with the questions you are due to face. The only exception to this advice is if you feel it may tier you.
  2. Read the instructions carefully (don't skip them!). Remember, each section has its own rules to follow.
  3. Don't spend too much time on a single question. If you finish the questions before the time is up, you can go back to questions you weren't sure of.
  4. The time limit does not affect your score. Completing the test with time to spare will not improve your score, so make sure to use every minute and answer all of the questions. Don't leave any questions unanswered!
  5. Pay attention to where you are, or are not, allowed to use common sense and world knowledge. In some sections, you must base your answer solely on the passage, and in others, you have to use common sense to reach a conclusion.
  6. Brush on your formal logic. For example, did you know that ‘most bears like beets’. Since this sentence only states that ‘most’ bears like beets, not ‘all’, it means that not all bears enjoy beats.

Watson Glaser FAQs

Is the Watson Glaser Test Hard?

The Watson Glaser Critical Thinking Appraisal is considered to be one of the hardest pre-employment tests on the market today, due to its unique and counterintuitive set of rules, as well as its focus solely on critical thinking.

What Is the Difference between Watson Glaser II and III?

The Watson Glaser III is a revision of the common WG-II test. The main difference is that the WG-III can be taken in an unsupervised setting, due to the "item-bank" from which questions are randomly selected.
However, WG-II and WG-II are identical in terms of topics, question number, and allowed time.

How many questions are in the Watson Glaser Test?

The Watson Glaser test includes 40 questions, divided into five different sections.

Is the Watson Glaser Test Timed?

The Watson Glaser is normally timed allowing you up to 30 minutes to complete all 40 questions. There are also untimed versions for candidates requiring adjustments. Note that every section is timed separately.

What Is the Difference Between Watson Glaser Forms D and E?

According to the official Watson Glaser Manual, forms D and E are a remnant of the revision the test has gone through in recent years. The older version contained two different forms, named A and B. Practically speaking, for you as a test-taker, both forms are equivalent and share the same difficulty level, structure, and format.
