Thinking about a career in law, consulting, or finance? Then chances are the Watson Glaser Test will cross your path.
For many top law firms, banks, and global organisations, it’s the gold-standard assessment for measuring critical thinking — your ability to:
- Evaluate information
- Spot assumptions
- Draw conclusions
- Make sound decisions under pressure
This guide gives you everything you need to know about the Watson Glaser Test in 2025:
- What it is
- Why employers use it
- The versions you might face
- Most importantly — how to prepare and score high
What Is the Watson Glaser Test?
The Watson Glaser Critical Thinking Appraisal (WGCTA) is a psychometric test created by Goodwin Watson and Edward Glaser. It’s designed to measure how well you can:
- Think logically
- Analyse complex information
- Make reasoned judgments
It’s not just about intelligence — it’s about how you use information.
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:
- Inference – Decide whether conclusions are true, false, probably true, probably false, or if there’s insufficient data.
- Recognition of Assumptions – Spot whether a statement is based on unstated beliefs.
- Deduction – Test if a conclusion logically follows from given facts.
- Interpretation – Judge if generalisations or conclusions can be drawn beyond reasonable doubt.
- 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 (2025 Update)
- Duration: Around 30 minutes (Watson Glaser III is strictly timed)
- Number of Questions: 40 (spread across the 5 sections)
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 the Test Is Scored
Your results may be presented as:
- Raw Score – number of correct answers
- Percentile Rank – where you stand compared to others (e.g. 80th percentile = better than 80% of candidates)
Target Score: Aim for 75–80% or higher to stand out — especially in competitive industries like law where firms use strict cut-off scores.
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.

FAQs: Watson Glaser Test
Is the Watson Glaser Test multiple choice?
Yes, the Watson Glaser Test is entirely multiple choice. Each question presents a statement or scenario followed by a set of possible answers, and you must choose the most appropriate one based on critical thinking principles. The answer options vary slightly depending on the section - for example, in the Inference section, you might choose from options like “True,” “Probably True,” “Insufficient Data,” “Probably False,” or “False.” For other sections, you can find only 2 options to choose from. The format is designed to assess your ability to reason logically and make sound judgments based on the information provided.
Can I take the Watson Glaser Test online?
Yes—most employers offer a secure online assessment.
How many times can I take the Watson Glaser test?
Technically multiple times, but employers usually consider your most recent or first attempt.
Is there a passing score for Watson Glaser?
