The Watson Glaser Critical Thinking Appraisal (WGCTA) is the most widely used critical thinking assessment for professional recruitment and development — used by law firms, consulting firms, financial institutions, government agencies, and graduate programs to evaluate logical reasoning, argument analysis, and decision-making ability. This complete guide covers what the Watson Glaser measures, the five section breakdown, how scoring works, and evidence-based strategies for improving your performance.
The Watson Glaser Critical Thinking Appraisal is a standardized psychometric test that measures an individual's ability to think critically — specifically, the ability to interpret information objectively, identify assumptions, evaluate arguments, and draw sound conclusions from evidence. It was developed by Goodwin Watson and Edward Glaser in the 1920s and has been continuously refined through multiple editions. Practice with the free Watson-Glaser Critical Thinking Appraisal practice test on PracticeTestGeeks (7 questions with answer explanations).
Unlike personality tests or IQ tests, the Watson Glaser specifically measures applied reasoning — how well you process written information and make logical judgments under realistic conditions. The current version (Watson Glaser III, or WG-III) features a timed format with scenarios drawn from business, law, policy, and everyday contexts.

1. Inference
You are given a passage of factual information and a list of possible inferences (conclusions that might be drawn). You decide if each inference is: True, Probably True, Insufficient Data, Probably False, or False — based solely on the passage. Key skill: distinguish what the passage actually says from what seems plausible but isn't stated.
2. Recognition of Assumptions
You are given a statement and a list of proposed assumptions. You decide whether each assumption is 'Made' (taken for granted in the statement) or 'Not Made.' Key skill: recognize unstated premises that must be accepted for the statement to be true — without over-reading.
3. Deduction
You are given premises and must decide whether a conclusion 'Follows' or 'Does Not Follow' from those premises strictly according to logic. Key skill: formal logical reasoning — even if a conclusion seems true in general, it only 'follows' if it's logically required by the premises given.
4. Interpretation
You are given a passage and must decide whether each conclusion 'Follows' or 'Does Not Follow' — but this time based on evidence rather than strict logic. Key skill: weighing the weight of evidence rather than applying formal deduction rules.
5. Evaluation of Arguments
You are given a question and a list of arguments. You decide whether each argument is 'Strong' or 'Weak' — a strong argument is both relevant to the question and important. Key skill: separating emotionally compelling arguments from logically sound ones.

Passage: Residents of Maplewood report that since a new highway opened nearby, traffic on Main Street has decreased. Inference: 'The new highway has diverted traffic away from Main Street.' How should this inference be rated?
Answer: B. Probably True
The inference is probably true because a new parallel highway diverting traffic is the most logical explanation for a reduction in traffic on Main Street.
Statement: 'Should social media platforms be legally liable for user-posted misinformation?' Argument: 'No, because social media CEOs are already very wealthy and shouldn't be punished further.' Is this argument strong or weak?
Answer: B. Weak, because the wealth of executives is irrelevant to platform liability policy
The personal wealth of executives is irrelevant to whether a platform should bear legal responsibility for the content it hosts.
A speaker argues: 'We should not allow any exceptions to the no-phone policy in meetings. Once we allow one exception, everyone will demand exceptions, and soon no one will follow any rules.' Which fallacy is this?
Answer: B. Slippery slope
Slippery slope assumes without justification that one minor concession will inevitably lead to a complete breakdown of the rule.
Statement: 'Should the US eliminate daylight saving time?' Argument: 'No, because farmers in the Midwest prefer the current schedule.' Is this argument strong or weak?
Answer: B. Weak, because one group's preference is insufficient justification for a national policy
The argument is weak because the preference of a single interest group does not constitute a broadly relevant reason to maintain a national time policy.
