Why Law Firms Use the Watson Glaser
Law firms select on academic credentials, but a first-class degree does not distinguish a candidate's practical reasoning ability. The Watson Glaser fills this gap. Solicitors must read complex documents, identify hidden assumptions in contracts, draw sound inferences from incomplete information, and evaluate argument strength in negotiations β precisely the five skills the Watson Glaser measures.
The test also solves a volume problem. Magic Circle training contract programmes receive tens of thousands of applications for under 100 positions. A 30-minute online Watson Glaser administered before any human review cuts the candidate pool to a manageable size without relying solely on university name or degree grade. Firms can set a percentile cutoff and automatically advance candidates who clear it to the video interview or assessment centre stage.

Score Expectations for Magic Circle Law Firms
No Magic Circle firm publicly discloses its Watson Glaser cutoff score. What is known comes from candidate reports, law career forums, and recruiter commentary. The consensus picture is consistent: 70th percentile is an absolute floor; 80thβ85th percentile is competitive; 90th+ percentile is very strong.
The Watson Glaser short form (40 questions) is scored as a raw score out of 40, then converted to a percentile rank against a norm group of graduate-level candidates. A raw score of 28/40 typically maps to roughly the 65thβ70th percentile. A score of 32/40 is typically around the 80thβ85th percentile, though this varies by norm group version.
Silver Circle firms (Herbert Smith Freehills, Hogan Lovells, Ashurst, Simmons & Simmons, Travers Smith) use the Watson Glaser with comparable expectations β generally 70thβ80th percentile. US firms with strong London offices (Latham, Kirkland, Skadden) are increasingly adopting the Watson Glaser with similar benchmarks.
The practical implication: do not approach the Watson Glaser as a test you just need to pass. Aim to maximise your score. One or two additional correct answers can move a candidate several percentile points in a competitive graduate norm group. Practice with the Watson Glaser Inference section guide and Watson Glaser Deduction guide β these two sections are where most candidates lose points.
Many readers pair this guide with the watson glaser practice test free to check their readiness before exam day.

Law Firm Watson Glaser Preparation Checklist
- βTake a baseline timed practice test before any study β identify your weakest sections first
- βStudy the Inference section in depth: 'probably true / possibly true / insufficient data / probably false / definitely false' β the five-point scale trips most candidates
- βMaster Recognition of Assumptions: an assumption must be necessary for the argument to work, not merely plausible or related
- βFor Deduction questions: judge purely from given premises β suspend all real-world knowledge entirely
- βFor Interpretation: distinguish between what the data definitely shows vs what it suggests β err toward 'does not follow' unless evidence is explicit
- βFor Evaluation of Arguments: a strong argument must be both directly relevant AND important β general statements always count as weak
- βPractise under strict time pressure β 30β40 minutes for 40 questions means under 60 seconds per question
- βReview every error by section type: identify whether you are making reasoning errors or misreading the 5-point scale

- +Validates your knowledge and skills objectively
- +Increases job market competitiveness
- +Provides structured learning goals
- +Networking opportunities with other certified professionals
- βStudy materials can be expensive
- βExam anxiety can affect performance
- βRequires dedicated preparation time

Sample Watson-Glaser Critical Thinking Appraisal Practice Questions
Try these questions from our free Watson-Glaser Critical Thinking Appraisal practice tests. The correct answer and an explanation follow each question.
An assumption is considered 'not assumed' in the Watson-Glaser test when:
- A. It is explicitly stated in the passage
- B. It is necessary for the argument to hold
- C. The argument could still stand without it
- D. It is true in real life
Answer: C. The argument could still stand without it
If an argument remains valid without a given assumption, that assumption is not truly embedded in the reasoning.
Passage: Every applicant who passed the skills test was invited for an interview. Keiko was not invited for an interview. Conclusion: Keiko did not pass the skills test. What is the status of this conclusion?
- A. True beyond reasonable doubt
- B. Probably true
- C. Insufficient data
- D. Probably false
Answer: A. True beyond reasonable doubt
Since passing guarantees an invitation, lacking an invitation confirms the test was not passed β a logically valid contrapositive.
Statement: All of the top-ranked universities in the country require applicants to submit standardized test scores. Riverdale University does not require standardized test scores. Inference: Riverdale University is not one of the top-ranked universities.
- A. True
- B. Probably True
- C. Insufficient Data
- D. Probably False
- E. False
Answer: A. True
Since all top-ranked universities require test scores and Riverdale does not, it logically follows that Riverdale is not among the top-ranked universities.
Statement: Test scores in the school district dropped the year the district cut its arts programs. Inference: Cutting arts programs caused the drop in test scores. How should this inference be rated?
- A. True
- B. Probably True
- C. Insufficient Data
- D. Probably False
Answer: C. Insufficient Data
Test scores are affected by many variablesβteacher quality, demographics, fundingβso arts cuts alone cannot confirm causation.
