Everything You Need to Know

Initially developed by Goodwin Watson and Edward Glaser, The Watson-Glaser Critical Thinking Appraisal Test (WGCTA) understands and measures a candidate’s critical thinking skills. It’s a simple test that allows an employer to evaluate the candidate’s ability to recognize assumptions, assess arguments and draw conclusions based on those assumptions.

Critical thinking is considered a crucial factor because candidates who have it are often good decision-makers and arrive at informed, precise, and objective conclusions instantly. Solid decision making, problem-solving skills, and strategic thinking set the foundation for a successful candidate, organizations use these to screen and hire talented people.


Watson Glaser – an international test

The Watson-Glaser Critical Thinking Appraisal Test is published by Pearson Assessments, an international company with offices in 14 countries. The test features critical reasoning questions and is available in tens of languages and countries around the world including United States, United Kingdom, and Canada. The test is identical no matter the geography.

For example, leading law firms in the United Kingdom require new employees and recent university graduates to take the test. If you would like to practice law at Hogan Lovells, Clifford Chance, Linklaters, CMS or Freshfields you will need to do well on the Watson-Glaser. The test is also the basis for UK’s BCAT exam.


The test is available both without a time limit and a 30-minute timed version. Both versions consist of 40 questions divided into five sections. To pass the test, you need to have strong problem solving and analytical skills, and should be able to find a quick solution after examining all aspects of a problem. Critical Thinking Tests or Critical Reasoning Tests, such as the Watson-Glaser, are mostly used as one of the factors for hiring graduates, professionals, and managerial staff.

In the timed version, you will be given only 30 minutes to complete the Watson-Glaser Test of 40 questions.

Many legal firms and banks use this logical thinking test as a part of their selection process for ensuring they have only the most talented people on board. Candidates can either take the test online or can make use of the pen-paper format.

Critical thinking can be defined as one’s ability to rationally or logically think about a particular problem. It is also defined as the ability to process information from different sources reasonably and creatively. Companies utilize this test to hire strong, dedicated employees who will go on to become future leaders. An employee’s ability to effectively use information and make the right decision will ensure passing the test.

Test Features

The Watson-Glaser Critical Thinking Appraisal test is an internationally recognized, trusted test used by companies around the world to assess a candidate’s ability to:

  • Draw logical conclusions based on given facts
  • Analyze and interpret written information
  • Recognize the difference between assumptions and facts
  • Evaluate the strength of an argument
  • Draw correct inferences

These test questions are divided into three different categories: Recognize Assumptions, Evaluate Arguments, and Draw Conclusions. There are timed and untimed versions of the Watson-Glaser. Those taking the timed version have 30 minutes to complete the 40 questions. 

The test can be taken either online or using paper and pencil. It is available in US English, UK English, French, French Canadian, Dutch, Spanish and Latin American Spanish.

Technical Facts

There are 40 questions on the Watson-Glaser Critical Thinking Appraisal Test (WGCTA).

The test is divided into 5 sections:

  1. Inferences
  2. Recognition of assumptions
  3. Deduction
  4. Interpretation
  5. Evaluation of Arguments

All questions are multiple choice (five choices in inference and two choices in all the rest of the questions).

Two versions are currently available:

  • Watson-Glaser II forms D & E (computerized or pen & paper)
  • Watson-Glaser III (only computerized). 

The main difference between the two versions is that Watson-Glaser III is based on an item bank of questions and does not need a test proctor. 

The test is given by thousands of organizations and schools to measure job candidates and students’ ability to think critically. 

The test can be taken either online or offline.

There is no penalty for guessing the wrong answer.

Results Scale and Interpretations

Watson-Glaser results are broken down into two different reports, which are provided to the prospective employer. Some organizations may share results with test takers, especially if the test was given for developmental purposes:

  • Profile Reports
  • Development Report

Profile Report

The profile report rates you with an overall percentile score, which is further broken down into the candidate percentile in three subscales:

  • Recognize Assumptions: This test is all about understanding what the question states and analyzing whether the info mentioned is correct, or whether there’s any evidence that backs the stated information.
  • Evaluate Arguments: Evaluating arguments means logically working with a problem and critically evaluating it. It is about symmetrically analyzing the argument and the evidence provided.
  • Draw Conclusions: Candidates need to come to a logical conclusion based on the evidence provided. A candidate with strong critical thinking skills will be able to draw conclusions that would then lead to another conclusion.

While the Profile Report does include the raw number of correct answers, the percentile rank is more important, as it not only factors in the number of correct answers, but the difficulty of those questions as well. The percentile scoring system of WG-III accounts for question difficulty. The final percentile differs according to the norm group of the candidate (i.e. occupation, position, level of education).

The Profile Report will include the following information:

  • Percentile – your percentile position within your peer group
  • Stanine – your score on a nine-point scale (1-9)
  • Raw Score – the number of correct answers (out of 40)

For instance, here is a candidate’s sample score in measuring overall critical thinking:

Contrary to Watson-Glaser III, the WGCTA-II Profile Report also shows employers your raw scores in the three different categories, as seen below:

Development Report

The development report shows employers the strengths of their employees. When given to the candidates/employees, it also guides them how to further explore specific skill areas and improve their skills.

Recognize Assumptions

Candidates with skilled behavior in the area will identify what is being taken for granted, and explore diverse viewpoints on the subject. Identifying the assumptions will help you reveal information gaps and enhance your understanding of the subject.

If you scored ‘Strength To Leverage’ in this skill area, it means you possess strong skills in recognizing assumptions.

Evaluate Arguments

Candidates who can objectively and accurately evaluate arguments are likely to be hired by many organizations. Such candidates can overcome confirmation-bias and also possess the capability to analyze an argument’s reasoning and supporting evidence, and explore counter-arguments even when doing so is controversial. When evaluating controversial arguments, emotions can play a negative role, as they can cloud your evaluation capabilities.

If you scored ‘Further Exploration’ in this parameter it means that your skills are average when compared to other candidates.

Draw Conclusions

Drawing conclusions mean reaching the conclusion which logically follows the evidence available for a particular problem. Furthermore, reaching a conclusion means evaluating information from diverse sources, and even changing your position on a subject when warranted by the available evidence.

Watson-Glaser FAQs

What is the Watson-Glaser test?

The Watson-Glaser Critical Thinking Appraisal test measures an individual’s ability to digest information and understand situations. It is frequently administered as part of the hiring process, both for new hires and for existing employees looking to move up within their organization.

What are the main differences between the Watson-Glaser test versions (i.e. Watson-Glaser ii, forms D and E, and Watson-Glaser iii)?

There are two current versions of the test. The Watson-Glaser II Critical Thinking Appraisal (WGCTA II) forms D & E and Watson-Glaser III (WG III). While both versions of the test measure the same type of skills, there are some differences. 
WG III, which is the newest version, draws its questions from a large bank of items. Since every instance of the test is different, candidates can take the test without supervision. WG III is almost always timed (with some exceptions in limited locations). WG II, on the other hand, requires a proctor, and is not timed. 
Watson-Glaser I forms A, B, C, and S (Short) are obsolete and are no longer used in most cases.

What is a good score on the Watson-Glaser test?

Each company that administers the test has different standards. However, a score of 75% or higher will give you the best chance to be selected by a top law firm. Note that the scoring system takes into account the level of difficulty of each question—incorrectly answering easy questions or correctly answering difficult ones has higher significance on the final score.

Is the Watson-Glaser test hard?

The Watson-Glaser test is difficult, especially for individuals who aren’t familiar with the question types in the test. Familiarizing oneself with the test through practice tests will make it easier to move through the test quickly, and the tips and tricks available through most practice test companies will help you quickly answer questions.

How do you pass a critical thinking test?

The most important thing you can do to pass a critical thinking test is to take a practice test beforehand. The practice test will familiarize you with the type of questions you can expect to see on the test, and help you understand what the test is measuring.

What does the Watson-Glaser test measure?

The test will measure your ability to do the following:
1. Draw Inferences
2. Recognize assumptions
3. Think critically and logically interpret information
4. Draw conclusions based on given facts
5. Evaluate arguments as weak or strong

What are the sections of the Watson-Glaser test?

The test is divided into 5 sections: 
1. Inferences: In this section, you will be provided with a list of possible inferences which you will be asked to rate as true or false.
2. Recognition of Assumptions: In this section, you will encounter assumptions based questions.
3. Deductions: You will be asked to make deductions using the information from the passage. Given a few proposed conclusions, you will be asked to decide for each if it: ‘follows’, or does not ‘follow’ the passage’s logic.
4. Interpreting information: In this section, you will need to interpret information from the questions to decide if each conclusion is based on the given information or not. Your answer should be based solely on the provided information and not on prior knowledge which may mislead you.
5. Analyzing arguments: To examine arguments, you will have to assess whether the provided statement is strong or weak.

How many questions are on the Watson-Glaser test?

There will be 40 multiple choice questions that you need to complete in only 30 minutes in the timed version.

Why is there a timed version of the test?

Watson-Glaser believes that it is essential for employee assessment to analyze and make decisions under pressure, which is why the test is timed. In the timed version, you will only have 30 minutes to complete the test.

The modules and tests are very helpful in preparing for Watson Glaser Critical Thinking pre-employment testing. Note: it is imperative to read thoroughly every word and to not just glance over the statements and assumptions. Overall very helpful to have an idea in advance of what to expect.

    This is a comprehensive and carefully prepared preparation material for the WG-CTA developed by a leading author in the field of critical thinking. Areas of improvement include the following: (1) add a diagnostic test to provide a baseline level of competence thereby allowing participants to identify weak areas early in their preparation and use this knowledge to better target their learning; (2) the theory provided in the “question types guidance” can be significantly strengthened with more explanation, techniques, and tips. In particular, the assumptions section could be expanded to include important topics such as the difference between necessary and sufficient assumptions (some times a provided sufficient but not necessary assumption serves as a challenging wrong option), and types of necessary assumptions apart from missing inferential links (e.g. presumptions and overlooked possibilities); (3) more challenging questions need to be added to match the difficulty of the real test.

    The information in the materials is not fully correct. They do give you all 5 inferences to chose from and not the 3 the iprep suggests. Also, the test automatically pauses in-between each of the 5 sections but does not allow you to jump back and forth between sections. I have a few minutes left and wanted to review some of the assumptions and it would not allow me. The order they do these practice tests and number of questions is correct. Questions I was given were much harder than the prep. However, without this course I would have surely failed this test.
