What this test shows

This 10-question quiz is loosely modelled on the Watson-Glaser Critical Thinking Appraisal, the assessment most commonly used by employers (especially law firms and consultancies) to screen for reasoning ability. The questions cover the five skills the original test measures: inference, recognition of assumptions, deduction, interpretation, and evaluation of arguments. It's much shorter than the full Watson-Glaser, so treat it as a self-check rather than a formal score. The goal is to show you which kinds of reasoning come naturally and which trip you up.

Who this test is for and who it isn't

Best for

  • Candidates preparing for graduate-scheme or law-firm aptitude tests
  • Students wanting a quick check on their reasoning
  • Anyone curious how they handle assumptions and deductions under time pressure
  • Managers screening their own thinking before a tough decision

Skip it if

  • You need a certified, employer-grade score
  • You're looking for a full IQ or cognitive battery
  • You want a test of factual knowledge rather than reasoning
  • You're under exam conditions and need the real Watson-Glaser

What to do with your result

Don't focus on the total score, look at which questions you missed. If you slipped on the deduction questions, you'll benefit from formal-logic exercises. If you missed the assumption and interpretation items, the issue is usually pattern recognition rather than logic, and reading critical-thinking textbooks or practising press-release analysis helps more than logic puzzles. Re-take the quiz after a week of practice and compare.

FAQ

What is a critical thinking test?

A short assessment that measures how well you analyse arguments, spot assumptions, draw inferences from evidence, and apply formal logic. It's a test of reasoning, not of factual knowledge.

Is this the Watson-Glaser test?

No. It's a free, shorter quiz inspired by the same five skill areas the Watson-Glaser measures. If you need a certified score, you'll need the official assessment through an authorised provider.

What is a good critical thinking score?

On this 10-question quiz, 7 or higher is sharp, 9 to 10 is excellent. The real signal is which question types you miss, not the total.

How can I improve my critical thinking?

Practice three habits: separate evidence from conclusion, ask what assumption links them, and force yourself to generate at least one alternative explanation before accepting any claim.

How long does the test take?

Most people finish in 5 to 8 minutes. Don't rush, the questions reward careful reading rather than speed.

Are the questions multiple choice?

Yes. Each question has four options and exactly one correct answer worth one point.

Can I retake the test?

Yes, as many times as you like. Retaking it after some practice is a good way to see whether your reasoning is genuinely improving.
