Your 2026 Guide to the Watson Glaser Test & Critical Thinking Success

If you’re applying for roles in law, consulting, banking, or competitive graduate schemes, the Watson-Glaser Critical Thinking Test often sits between you and the interview. It’s designed to measure how reliably you can reason from written information—especially when the wording is tight and the clock is running.

Watson-Glaser in 30 seconds

• What it is: a critical-thinking assessment published by TalentLens (Pearson).
• What it measures: inference, assumptions, deduction, interpretation, and evaluation of arguments.
• Format: commonly 40 items, timed.
• Time limit: often 30 minutes, but TalentLens lists 30–40 minutes (can vary by employer).

What Is the Watson Glaser Test?

The Watson-Glaser Critical Thinking Appraisal (WGCTA) is a psychometric test that assesses how well you can:

• separate facts from interpretations
• spot hidden assumptions
• decide whether a conclusion must follow (or doesn’t)
• judge whether an argument is strong or weak based only on what’s written

In plain English: it’s not a “knowledge test”. It’s a discipline test—can you stay logical, literal, and consistent under pressure?

TalentLens describes Watson-Glaser as an assessment used for recruitment and development, with item-banked delivery available for remote testing.

That’s why industries where decisions matter — like law, finance, consulting, and leadership roles — use it to filter out candidates who can think fast and think smart.

The Watson Glaser Critical Thinking Appraisal (W-GCTA), published by TalentLens, is by far the most widely used critical thinking test.

It focuses on evaluating your ability to:

• Understand and evaluate arguments
• Recognise assumptions
• Draw conclusions
• Interpret evidence
• Make logical deductions

The 5 Core Sections of the Watson Glaser Test

The Watson Glaser exam consists of five separate sections which evaluate different skills:

1. Inference – Decide whether conclusions are true, false, probably true, probably false, or if there’s insufficient data.
2. Recognition of Assumptions – Spot whether a statement is based on unstated beliefs.
3. Deduction – Test if a conclusion logically follows from given facts.
4. Interpretation – Judge if generalisations or conclusions can be drawn beyond reasonable doubt.
5. Evaluation of Arguments – Separate strong arguments from weak ones.

Each section feels like a puzzle. The challenge? Staying focused and not letting assumptions or biases creep in.

Format and Timing (2026 Update)

Here’s what candidates most often see:

• Questions: typically 40 items
• Timing: typically 30 minutes, though TalentLens states 30–40 minutes timed (set-up can differ by employer)
• Delivery: online is common; remote/unproctored screening is possible depending on the employer

Practical pace target: plan for roughly 45 seconds per question. (That’s why method matters more than “thinking harder”.)

Versions of the Watson Glaser Test

• Watson Glaser II (Forms D & E): Older, fixed form, often paper-based.
• Watson Glaser III: The most common version today. Online, item-banked, timed, and widely used in recruitment.

Why Employers Use the Watson Glaser Test

Top firms aren’t just looking for bright candidates — they want professionals who can:

• Think critically under pressure
• Separate fact from opinion
• Make decisions quickly and logically
• Analyse evidence with precision

That’s why the Watson Glaser has become a staple in hiring for training contracts, graduate schemes, and leadership roles across the UK, US, and beyond.

Why the Watson Glaser Test Is So Challenging

If you’ve heard people say the Watson Glaser Test is difficult, they’re right. But here’s the truth: it’s not impossible — it just tests skills that most of us don’t consciously practise every day.

The challenge lies in three things:

• Time pressure – You’ve got 30 minutes to tackle 40 questions. That means you need both speed and accuracy.
• Tricky wording – The test is full of statements that seem obvious until you realise they’re designed to catch out assumptions and snap judgments.
• Pure logic only – You can’t rely on your personal knowledge or “gut feel.” The test forces you to base your answers only on the information given.

And that’s exactly why top employers love it. They want to see how you think when the clock is ticking and the pressure’s on.

The good news? Once you train your brain to think in Watson Glaser logic, the patterns become easier to spot.

Instead of seeing it as a “hard test,” reframe it as a game of logic you can master with practice.

Watson Glaser Test for Law Firms vs. Other Industries

Most people associate the Watson Glaser Test with law — and it’s true, it’s a staple for training contracts and vacation schemes at Magic Circle firms like Clifford Chance, Linklaters, and Hogan Lovells.

Why? Because lawyers must analyse evidence, question assumptions, and build arguments under pressure. The test mirrors that exact skill set.

But law isn’t the only industry where the Watson Glaser matters. It’s also used in:

• Finance & Banking – assessing risk management and decision-making under uncertainty.
• Insurance & Consulting – testing whether candidates can evaluate complex cases and recommend the best course of action.
• Corporate Leadership – requiring unbiased reasoning to make critical decisions.

The difference?

• Law firms use it as a strict filter — miss the cut-off score, and you’re out of the running.
• Other industries often use it alongside other assessments, meaning a strong performance can make you stand out even more.

So whether you’re aiming for a law firm or a corporate role, treating the Watson Glaser as a career gateway test is the smartest mindset.

How scoring works (and what “good” looks like)

Scores are commonly reported as:

• a raw score (how many correct)
• a percentile (how you performed versus a comparison group)

What to aim for: if you’re targeting highly competitive roles, you generally want to be comfortably above average—because some employers apply cut-offs or use the score as a differentiator. (Exact benchmarks vary by employer and cohort.)

---

Preparation strategy that actually moves your score

1) Build a repeatable method per section

Don’t just “do more questions”. Instead, practise with a rule you apply every time:

• Inference: label what is stated vs what is implied. If it’s not supported, it’s Insufficient Data.
• Assumptions: ask: “Would the argument collapse if this wasn’t true?” If yes, it’s an assumption.
• Deduction: treat statements like mathematics: if it’s not guaranteed, it doesn’t follow.
• Interpretation: stay conservative—only accept what the passage supports beyond reasonable doubt.
• Arguments: “Strong” = relevant + important to resolving the issue. “Weak” = off-topic, emotional, or trivial.

2) Train timing, not comfort

Do short, timed sets (e.g., 10 questions) until you can keep pace without panic.

3) Review like a lawyer: why you were wrong

For every mistake, write one line:

• “I added an assumption about X”
• “I confused ‘must’ with ‘might’”
• “I ignored a limiting word (‘some’, ‘only’, ‘unless’)”

That one-line diagnosis is what prevents repeat errors.

Test-day checklist (quick and realistic)

• Do one final timed mini-set the day before
• Sleep properly (fatigue destroys precision)
• Set up a distraction-free space (if remote)
• If stuck, move on—one question isn’t worth your overall pace
• Keep your rule: use only what’s on the page

Watson Glaser Critical Thinking Appraisal Explained

The full official name is the Watson Glaser Critical Thinking Appraisal (WGCTA). It appraises a candidate’s critical thinking across the same five sections. You might see different names used interchangeably:

• Watson Glaser Critical Thinking Test
• Watson Glaser Critical Thinking Appraisal
• Watson Glaser Critical Reasoning Test

All refer to the same core assessment, developed in 1920 by Goodwin Watson and Edward Glaser. The test is published by TalentLens (part of Pearson), which, as we know, does not offer tests directly to individual users but works exclusively with organization, particularly law and other businesses.
