Watson-Glaser Critical Thinking Appraisal

What is the Watson–Glaser Critical Thinking Appraisal?

The Watson–Glaser Critical Thinking Appraisal is a widely used critical-thinking test designed to measure your ability to evaluate information, analyse arguments, identify assumptions, and draw logical conclusions.

The test is commonly used in recruitment and selection for roles where sound judgement and careful reasoning are important. It is especially common in law, consulting, finance, management, graduate recruitment, and other professional roles where candidates need to assess information objectively and make well-supported decisions.

Unlike tests that measure knowledge or technical skills, the Watson–Glaser focuses on how you think. It assesses whether you can separate facts from assumptions, avoid unsupported conclusions, and judge arguments based on logic rather than personal opinion.

Here we will cover what you need to know about the Watson–Glaser Critical Thinking Appraisal.

Test Format and Timing

The exact format may vary depending on the test version and the employer administering it.

Common features include:

• The test is usually computer-based.
• Many modern versions contain around 40 multiple-choice questions.
• The time limit is often around 30 minutes.
• Some versions may be adaptive, meaning the difficulty of the questions can adjust to your performance.
• Older or longer versions may contain more questions and have a longer time limit.
• You are usually required to answer based only on the information given in the question.

There is usually no penalty for incorrect answers, so it is better to answer every question than to leave questions blank.

What does the Watson-Glaser test measure?

The Watson–Glaser Critical Thinking Appraisal includes the following five question categories:

1. Inference

2. Recognition of Assumptions

3. Deduction

4. Interpretation

5. Evaluation of Arguments

Read more about each category below.

Inference

Inference questions test your ability to judge how strongly a conclusion is supported by the information given.

You are usually given a short passage followed by a statement. Your task is to decide whether the statement is true, probably true, impossible to determine, probably false, or false.

These questions test whether you can distinguish between what is clearly supported, what is likely, and what cannot be concluded from the evidence.

Recognition of Assumptions

Assumption questions test your ability to identify unstated assumptions in an argument.

An assumption is something that is not directly stated but must be accepted as true for the argument to work. In these questions, you are usually given a statement or argument followed by a proposed assumption. Your task is to decide whether the assumption is being made.

Deduction

Deduction questions test whether a conclusion logically follows from the information given.

You must treat the information in the statement as true, even if it does not match your real-world knowledge. The conclusion follows only if it must be true based on the statement.

Interpretation

Interpretation questions test your ability to understand written information and decide whether a conclusion is properly supported by the evidence.

These questions are similar to deduction questions, but they often focus more on the overall meaning of a passage. You must decide whether the conclusion follows from the information as a whole.

Evaluation of Arguments

Evaluation of arguments questions test your ability to judge whether an argument is strong or weak.

A strong argument is directly relevant to the question and gives an important reason for or against the issue. A weak argument may be irrelevant, minor, emotional, exaggerated, or poorly connected to the question.

How is the Watson-Glaser test scored?

The Watson–Glaser is usually scored by giving one point for each correct answer. Incorrect answers usually receive zero points, and there is normally no negative marking.

However, employers often look beyond the raw score. Your result may also be compared with a relevant norm group, such as graduates, managers, professionals, or other job applicants.

This means your result may be reported as a percentile score.

For example:

• 50th percentile means you scored higher than about 50% of the comparison group.
• 75th percentile means you scored higher than about 75% of the comparison group.
• 90th percentile means you scored higher than about 90% of the comparison group.

A good score depends on the role, the employer, the applicant pool, and the norm group used.

How to prepare for the DAT Next Generation

Preparation can make a significant difference in your performance. The Watson–Glaser is not about memorising facts. It is about learning how to apply critical-thinking rules consistently.

Here’s how to get ready:

• Practise each question type separately before taking full tests.
• Learn the difference between “possibly true” and “definitely supported”.
• Avoid using outside knowledge when answering questions.
• Read the wording carefully, especially words such as all, some, none, must, may, always, and never.
• Focus on whether conclusions are supported by the information given.
• Practise under timed conditions so you become comfortable with the pace of the test.
• Review your mistakes carefully to understand why an answer is correct or incorrect.

Tips for taking the Watson–Glaser

• Base your answers only on the information given in the question.
• Do not answer based on your personal opinion.
• Do not assume something is true just because it sounds realistic.
• Watch out for conclusions that are possible but not proven.
• In assumption questions, ask whether the argument needs the assumption to work.
• In deduction questions, ask whether the conclusion must be true.
• In argument evaluation questions, judge relevance and importance, not whether you agree.
• If you are unsure, eliminate clearly wrong answers and make your best choice.
