We've created a comprehensive Watson Glaser prep course designed to help you succeed. Our course closely mimics the actual test conditions and question types, allowing you to identify and improve your weaker areas across all five critical thinking skills. With this focused preparation, you'll be confident and ready to excel on test day.
Why preparation matters: The Watson Glaser is a standard requirement for many training contracts and vacation scheme applications, testing inferences, assumptions, deductions, interpretation, and argument evaluation. It's known for being genuinely difficult - not because it demands knowledge, but because it challenges intuition with subtle reasoning and counterintuitive rules that catch even well-prepared candidates off guard. Our practice tests are deliberately tuned to expose these traps, so when test day comes, you'll spot them instantly instead of falling for them.
Read the following text, and then choose whether the question below is true or false to varying degrees according to the following text:
Virtual employees, or employees who work from home via a computer, are an increasing trend. In the US, the number of virtual employees has increased by 39% in the last two years and 74% over the previous five years. Employing virtual workers reduces costs and makes it possible to use talented workers no matter where they are located globally. Yet, running a workplace with virtual employees might entail miscommunication and less camaraderie and can be more time-consuming than face-to-face interaction.
The marked advantage of virtual employee hiring is the ability to benefit from the output of unsociable employees without involving them in face-to-face interactions.
Wrong
Wrong
Wrong
Wrong
Correct!
Answer
The correct answer is 'False'.
The words “marked advantage” insinuate that the ability to benefit from unsociable employees is the most significant advantage. However, that advantage is not even mentioned in the text. That means that the answer is either False or Probably False.
The text specifically mentions the benefits of face-to-face meetings on social interaction: “a workplace with virtual employees might entail miscommunication and less camaraderie and can be more time-consuming than face-to-face interaction”. The conclusion, however, refers to the problems it creates, which is negated by the general message of the passage.
Below is a statement followed by a proposed assumption. Determine whether the statement implies the proposed assumption, treating it as true without needing to justify it.
"Increasing the number of employees in the department will increase its business performance."
Proposed Assumption:
It is possible to predict the impact of department size on business performance.
Correct!
Wrong
Answer
The correct answer is ‘Assumption Made’.
To see why the assumption is made, let’s use the Negative Test algorithm:
Step #1 – negate the assumption – “It is impossible to predict the impact of department size on business performance.”
Step #2 – check if the validity of the original statement changes. In our case, it does, since if there is no way to measure the effect of department size on business performance, any statement trying to predict such an effect is meaningless.
Step #3 – if the statement is not valid anymore, then the assumption was made.
Below you are presented with a premise followed by a suggested conclusion.
I have a nine-month-old baby at home, and she usually agrees to be put to bed, where she falls asleep promptly. But every time her grandparents visit in the evening, she cries when I put her to bed, and she continues to cry for an hour.
Proposed Conclusion:
My baby’s difficulty is mostly physiological—her grandparents give her chocolates to eat, and the sugar makes her hyperactive.
Wrong
Correct!
Answer
The correct answer is: ‘Conclusion Does Not Follow’.
The conclusion proposes a reason that is neither given explicitly in the text nor probable beyond a reasonable doubt. It provides an explanation that stems from our own personal perceptions.
The Watson Glaser Test measures a comprehensive range of critical thinking skills, essential for success in various professional settings. These skills include the ability to analyze and interpret verbal information, draw logical conclusions, and evaluate arguments effectively. The test challenges candidates to think in a creative and logical manner, considering multiple perspectives and systematically evaluating information.
Additionally, it assesses your ability to recognize assumptions, make logical deductions, and interpret information clearly and concisely. By providing a thorough evaluation of your critical thinking ability, the Watson Glaser Test helps employers identify candidates who can approach problems methodically and make well-reasoned decisions. Head to our Watson Glaser test guide page to learn more about the test structure, scoring, and more.
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.
A good score is 33–34 correct answers out of 40, placing candidates at around the 80th percentile — the benchmark typically required for competitive roles such as training contracts at top law firms. Scores are assessed relative to other test takers, so the more applicants competing for a role, the higher the score needed to progress.
The Watson Glaser test assesses five critical thinking skills: logical reasoning (Inferences), critical judgement (Assumptions), logical-based reasoning (Deduction), analytical reasoning (Interpretation), and argument evaluation (Evaluation of Arguments). Each section has its own rules and question format, and success requires mastering all five - candidates cannot compensate for weakness in one area by performing strongly in others.
