Watson Glaser Test for Law Firms — Magic Circle Guide 2026
How Magic Circle and Silver Circle law firms use the Watson Glaser test, what scores you need, and how to prepare for training contract applications.
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 — 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; 80th–85th 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 65th–70th percentile. A score of 32/40 is typically around the 80th–85th 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 — generally 70th–80th 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 — these two sections are where most candidates lose points.
When Does the Watson Glaser Appear in the Training Contract Timeline?
The Watson Glaser almost always appears early in the process — before video interviews, assessment centres, or partner interviews. A typical Magic Circle timeline looks like this:
- Application form — academic credentials, motivational questions, work experience
- Online assessments (Watson Glaser + SJT or verbal reasoning) — automated cutoff applied here
- Video interview or recorded interview — competency and commercial awareness
- Assessment centre — group exercises, case study, written exercise, partner interview
- Training contract offer
Failing the Watson Glaser ends the application at Stage 2. Because firms receive 10,000–30,000 applications per cycle, this is a pure automated filter — no human reviews your form before you clear the Watson Glaser. This makes preparation non-negotiable for competitive candidates. Understand the Watson Glaser Assumptions section thoroughly — it is the section most commonly cited by candidates as unexpectedly difficult.
