The Watson Glaser Critical Thinking Appraisal (WGCTA) is now delivered primarily online — through the Pearson TalentLens portal or employer-hosted assessment platforms. Whether you are applying to a law firm, consulting practice, or graduate programme, you are most likely completing this test remotely. This guide covers exactly how online WGCTA delivery works, what technical setup you need, and how to avoid common pitfalls on test day.
The Watson Glaser critical thinking test is browser-based and requires no software installation. Candidates receive an emailed link from the employer or Pearson TalentLens and access the test directly in a web browser. The assessment is strictly time-limited: the standard WGCTA form runs 40 minutes for 40 questions, while the shorter WGCTA-II runs 30 minutes for 40 items.
Once started, the timer cannot be paused. You cannot go back to a completed section in most employer configurations, so reading each stimulus passage carefully on first encounter is essential. Answers are auto-scored the moment you submit, and results are sent to the employer portal — you typically do not see your score unless the employer chooses to share it.
The platform used depends on the employer: large UK law firms commonly use Pearson TalentLens directly, while some employers embed the assessment in SHL, Korn Ferry, or Taleo portals. The underlying test content is identical regardless of delivery platform. Use our watson glaser test practice to build the pacing discipline that the online format demands.
A modern desktop or laptop computer (Windows 10+ or macOS 12+). Supported browsers: latest Chrome, Firefox, Edge, or Safari. Disable browser extensions and ad-blockers before starting. Stable broadband connection of at least 5 Mbps.
A quiet, well-lit room with no other people present. A clean desk — some proctored versions use webcam monitoring and will flag cluttered environments. A single screen only; dual-monitor setups may trigger flags on proctored tests.
No pausing — the clock runs from the moment you start. No going back to previous questions in most configurations. No external materials allowed (notes, printed passages, calculators). Work through each of the 5 sections: Inference, Recognition of Assumptions, Deduction, Interpretation, Evaluation of Arguments.
Screenshot any error messages immediately. Contact the employer's HR team — not Pearson — first. Pearson TalentLens support: talentlens.support@pearson.com. Most employers can issue a fresh test link if a genuine technical failure is documented within 24 hours.
Employers choose between two delivery models, and knowing which one you face changes how you prepare your workspace.
Unsupervised (at-home, unproctored): The most common format for initial screening rounds. You receive an access link by email and complete the test at your own convenience within a specified window (often 3–7 days). There is no live proctor watching, but your browser activity, timing metadata, and response patterns are logged. Attempting to look up answers or using assistance will show in the timing data. These tests are often re-validated at an in-person assessment centre if you progress. For best results, treat an unproctored test exactly as you would a supervised one — same quiet room, no assistance. Review the Watson Glaser critical thinking appraisal to understand exactly what skills are assessed across all five sections.
Supervised (proctored online): Used increasingly by elite law firms and graduate schemes. You connect at a booked time, a live or AI proctor activates via your webcam and microphone, and your screen may be recorded throughout. ID verification (passport or driving licence) is required at the start. Ensure your webcam driver is up to date and your microphone is unmuted but environment is silent. A secondary device (phone) used during a proctored session will result in immediate disqualification.
Assessment centre (in-person supervised): Some employers ask top candidates to re-sit the Watson Glaser on-site. The test is identical in content but administered on employer hardware. No personal devices, no preparation materials allowed. Your Watson Glaser critical thinking preparation transfers directly — the format difference is purely logistical.
Run through this before clicking the start link on the day of your Watson Glaser online test:
Technical failures during a timed online assessment are stressful but manageable if you act quickly. The most common issues are: browser freezing on submission, internet dropout mid-session, and webcam disconnection during a proctored sitting.
Browser freeze or crash: Refreshing the page will usually resume the test at the same question, with the timer still running. If the test does not reload within 60 seconds, close the browser, reopen it, and navigate back to the test link from the employer email. Most platforms save progress server-side in real time.
Internet dropout: Switch to mobile hotspot if broadband fails. The timer continues in the background on the server, but answers entered before disconnection are usually preserved. Notify the employer within 30 minutes of the session ending, before results are reviewed.
Proctoring disconnection: If your webcam or microphone drops during a live-proctored session, stay visible and reconnect the device. The proctor may type a message in the chat panel — read it before continuing. Do not leave the camera frame.
Understanding how Watson Glaser scoring works helps you prioritise: if you lose connection with 5 minutes remaining and 30 questions answered, the already-answered items still count. Submit what you have rather than waiting and running out of time entirely. Our watson glaser test practice simulates the clock pressure so that technical stress on the day does not derail your thinking.
