Watson-Glaser Pass Marks: What Magic Circle, Silver Circle, and US BigLaw Actually Cut At
Magic Circle cuts at the 75th-80th percentile. Silver Circle at 70th-75th. Mid-market at 65th-75th. Full firm-tier lookup table and 7-day prep plan inside.
If you are sitting the Watson-Glaser this cycle, the question that actually decides your application is not "what is a good score" but "what does this specific firm cut at." The answer is more knowable than the test prep industry pretends. Magic Circle firms, Silver Circle firms, and US BigLaw all operate on percentile cutoffs that have stayed roughly stable for a decade, and the numbers below are the cutoffs candidates and former graduate recruiters report consistently across forums, university careers services, and prep providers.
Quick takeaways
- There is no published universal Watson-Glaser pass mark. Cutoffs are firm-specific and percentile-based.
- Magic Circle firms cut at the 75th to 80th percentile. Roughly 75 to 80 percent raw is the safe target.
- Silver Circle and US BigLaw London offices cut slightly lower, typically 70th to 75th percentile.
- Mid-market and regional UK firms cut around the 60th to 70th percentile.
- The Government Legal Service, Bar Standards Board pupillage routes, and in-house counsel programmes use Watson-Glaser more sparingly and at lower cutoffs.
- The test is graded on percentile rank against a comparison group, not against an absolute mark. Your percentile, not your raw score, is what the firm sees.
How the Watson-Glaser actually decides whether you advance
The Watson-Glaser Critical Thinking Appraisal is a 40-question, 30-minute test in its standard form, with an 80-question, 60-minute long form used by a smaller number of firms. It runs five sections: inferences, recognising assumptions, deductions, interpretation, and evaluation of arguments. Each section uses its own response scale, and a misread scale costs marks across multiple questions in a single section.
The test is published by Pearson TalentLens. Pearson scores your raw answers and converts them to a percentile rank against a comparison group, typically "graduate" or "professional" norms. The firm sees the percentile. They compare it to a cutoff they have set in advance for the role and intake, and either advance or reject you based on that single number.
A small number of firms, Clifford Chance most notably, send candidates a feedback PDF showing their percentile and section-level breakdown. Most firms send a pass or fail email with no score disclosed.
Watson-Glaser cutoffs by firm tier
Five tiers cover almost every Watson-Glaser-using firm you might apply to.
Magic Circle. The five top London-based firms — Allen & Overy, Clifford Chance, Freshfields Bruckhaus Deringer, Linklaters, and Slaughter and May — set the highest cutoffs. Reported pass marks cluster around the 75th to 80th percentile. Slaughter and May historically did not use the Watson-Glaser at all and instead ran their own assessment, but the rest of the Magic Circle treat the test as a hard pass-or-fail filter. A Watson-Glaser score below the cutoff at any Magic Circle firm ends your application before a human reads your form.
Silver Circle and elite US firms in London. The Silver Circle (Herbert Smith Freehills, Macfarlanes, Travers Smith, Ashurst, Bryan Cave Leighton Paisner) and US BigLaw London offices (Latham & Watkins, Kirkland & Ellis, Skadden, Sullivan & Cromwell, Weil Gotshal & Manges, White & Case) set cutoffs slightly lower, typically 70th to 75th percentile. US firms using their own internal assessments may not use the Watson-Glaser at all, but those that do tend to run cutoffs closer to the Magic Circle than to the mid-market.
International and large mid-market firms. Hogan Lovells, Norton Rose Fulbright, DLA Piper, Baker McKenzie, Bird & Bird, Dentons, CMS, RPC, Eversheds Sutherland, Pinsent Masons. Cutoffs reported in this band are typically 65th to 75th percentile. There is more variability here than at the Magic Circle level: some firms apply a strict percentile cutoff, others use the Watson-Glaser as one input among several at the application sift.
Specialist and regional firms. Burges Salmon, Mills & Reeve, TLT, Hill Dickinson, Kennedys, Bates Wells, HFW. Cutoffs in this band cluster around the 60th to 70th percentile. The test is more often used as a screen against the bottom of the applicant pool rather than as a precision filter on the top.
Public sector legal employers. The Government Legal Service uses the Watson-Glaser as part of its multi-stage assessment, but the cutoff is generally lower than commercial firms — reported around the 60th percentile — and the test is weighted alongside other components rather than treated as a hard filter.
What the percentile cutoffs translate to in raw marks
The raw-to-percentile conversion is not published by Pearson, but the rough mapping based on community-reported scores is consistent enough to be useful.
A raw score around 28 out of 40 (70 percent) typically lands at the 60th to 65th percentile. A raw score around 30 out of 40 (75 percent) typically lands at the 70th to 75th percentile. A raw score around 32 out of 40 (80 percent) typically lands at the 80th percentile. A raw score of 34 or above (85 percent and up) typically clears the Magic Circle bar comfortably. A raw score of 36 or above (90 percent) is at or near the 90th percentile and clears every cutoff for every firm tested.
The mapping is not a straight line because the Watson-Glaser punishes wrong answers as well as blanks. A candidate who gets 32 right and 8 wrong scores differently from a candidate who gets 32 right and 8 blank, even though the raw count of correct answers is identical. Section weighting also varies: the inferences and evaluation-of-arguments sections tend to have heavier weight in the final score than the deductions and interpretation sections.
Why the Watson-Glaser is harder than candidates expect
The Watson-Glaser does not punish time pressure the way the CCAT or Wonderlic do. Thirty minutes for 40 questions gives you 45 seconds per question, which is generous compared to cognitive screens like the CCAT (18 seconds per question). The difficulty is in the discipline.
The single biggest source of lost marks: candidates use outside knowledge. The test instructs you to reason only from the passage in front of you, even when the passage states something you know to be factually wrong. Candidates who answer based on what they know rather than what the passage says lose 4 to 8 marks across a single sitting. This is the most consistent failure pattern, and it is also the easiest to fix with practice.
The second biggest source: candidates confuse the response scales between sections. Inferences uses a five-point scale (true, probably true, insufficient data, probably false, false). Recognising assumptions uses a binary scale (assumption made, assumption not made). Deductions uses a binary scale (conclusion follows, conclusion does not follow). Switching scales between sections without re-reading the instructions costs marks predictably, and the loss is concentrated in the section the candidate switched into.
The third source: the inferences section requires you to rate "probably true" versus "true" with surgical precision. "True" means the passage entails it. "Probably true" means the passage makes it more likely than not but does not entail it. Candidates who treat these as interchangeable lose marks in the section where the most marks are typically on offer.
How firm-specific the cutoffs really are
Cutoffs vary by firm, but they also vary within a single firm by intake year and by route. Three patterns worth knowing:
A given firm tends to set a higher cutoff for direct training contract applicants than for vacation scheme applicants who have already passed an earlier sift. The cutoff is calibrated to the volume of applications, not to a fixed standard.
A given firm can run different cutoffs for different recruitment cycles depending on application volume. A high-volume year tends to push the cutoff up. A weak year tends to push it down.
Some firms apply the cutoff at a section level rather than the overall test. A candidate scoring 80th percentile overall but 40th percentile on the inferences section can be rejected at a firm that requires balanced section performance, even though the overall score clears the published cutoff. Magic Circle firms in particular look at section balance.
The 7-day Watson-Glaser prep plan
Most candidates can move 8 to 12 percentile points in a focused 7 days. The lift comes from learning the rules, not from learning new content.
Day 1. Take a full-length 40-question timed mock. The point is to surface where your time went and which sections cost you marks. Score by section, not just overall. The section that lost the most marks is your priority for days 2 and 3.
Day 2. Drill the inferences section specifically. Practice the "true / probably true / insufficient data / probably false / false" five-point scale at speed. The key skill is calibrating "probably true" against "insufficient data": these are the two answers candidates confuse most often.
Day 3. Drill the recognising assumptions and deductions sections together. These two sections share a logical structure (binary judgement of whether a stated relationship holds) and the same skill transfers between them. The key discipline: assume the passage is true even when you know it is not.
Day 4. Drill the interpretation and evaluation of arguments sections. These reuse a smaller bank of question structures than the other three sections, and pattern recognition lifts your score quickly here.
Day 5. Take a second full-length timed mock. Compare to Day 1. The percentile gain from Day 1 to Day 5 is typically 6 to 10 points if the daily drills targeted weak sections.
Day 6. Pure error review. Go through every question you got wrong on the Day 5 mock and identify whether the error was a scale confusion, an outside-knowledge intrusion, or a genuine reasoning miss. The first two categories are fixable in minutes. The third is where remaining gain comes from.
Day 7. Rest. Do not learn new material. Sleep eight hours. Take the real test in the first half of your day if you have a choice of timing.
Beyond two weeks of focused prep, returns diminish hard. The Watson-Glaser has a per-candidate ceiling, and most candidates reach it within 10 to 14 days.

How to find out the cutoff for a specific firm
Firms generally do not publish cutoffs, but useful indirect signals:
If the firm runs the Watson-Glaser as the very first step before any human sift, the cutoff is set higher to mass-filter applicants. Magic Circle firms typically operate this way.
If the Watson-Glaser is administered after a paper sift, the cutoff is often lower because the firm has already filtered for fit. US BigLaw London offices and some Silver Circle firms operate this way.
If the firm sends a feedback PDF with your percentile (Clifford Chance is the most reliable example), you can compare your score across applications and gauge cutoffs by which applications advanced.
If you have already taken a Watson-Glaser for one firm in a cycle, your raw performance on the same test format at a second firm should be similar. If you cleared firm A but not firm B, the cutoff at B is higher than at A. This is the most reliable way to triangulate cutoffs without insider information.
What "passing" the Watson-Glaser actually means in practice
There is no universal pass mark. The test does not have a passing score the way a driving test does. What it has is a percentile rank, and your firm compares that percentile to a cutoff they have set.
The defensible target for almost any UK commercial law application is the 80th percentile, roughly 32 correct out of 40. This clears every cutoff for every Magic Circle firm with a margin, and it clears every cutoff for every firm below the Magic Circle comfortably. Hitting the 80th percentile means roughly 80 percent raw on a clean test.
If you are applying outside the Magic Circle, the 70th percentile (around 28 correct) is usually safe. Below the 60th percentile, you are at risk at almost every commercial firm.
FAQ
What is a good Watson-Glaser score?
The 80th percentile or higher is competitive at every UK commercial law firm. Raw score of around 32 out of 40 typically lands you at the 80th percentile. Magic Circle firms cut at 75th to 80th percentile, so 32 correct gives you a working margin.
What is the Watson-Glaser pass mark for Magic Circle firms?
Magic Circle firms (Allen & Overy, Clifford Chance, Freshfields, Linklaters) cut at the 75th to 80th percentile. There is no universal raw score, but candidates report that 30 to 32 correct out of 40 is roughly the threshold. Slaughter and May historically uses its own assessment rather than the Watson-Glaser.
How is the Watson-Glaser scored?
Pearson scores your raw answers and converts them to a percentile rank against a comparison group of graduate or professional candidates. Section weighting is not equal across the five sections: inferences and evaluation of arguments tend to carry more weight than deductions and interpretation.
Can I retake the Watson-Glaser?
Most firms allow only one Watson-Glaser sitting per application cycle. If you fail at one firm, you can apply elsewhere in a future cycle, but Pearson maintains a candidate database and your prior result may carry forward depending on the firm.
Is the Watson-Glaser harder than the CCAT?
They test different things. The Watson-Glaser is harder on logical precision, easier on time pressure. The CCAT is the opposite: easier on logical precision, brutal on time pressure. The CCAT gives you 18 seconds per question; the Watson-Glaser gives you 45.
Do all Magic Circle firms use the Watson-Glaser?
Allen & Overy, Clifford Chance, Freshfields, and Linklaters all use the Watson-Glaser at the time of writing. Slaughter and May runs its own assessment process and does not currently use the Watson-Glaser. Always check the current graduate recruitment page of the firm before applying.
What should I do if I score below the cutoff?
Most firms send a pass-or-fail email without revealing the score. If you suspect you are close to the cutoff and the firm is one of the few that publishes feedback (Clifford Chance is the most reliable example), use that data to gauge how much improvement is needed. Otherwise, apply to firms in tiers below your current performance and keep practising for the next cycle.
