With over 90 years of research behind it, the Watson-Glaser assessment is the benchmark tool for critical thinking evaluation. It enables organisations to make informed hiring and development decisions based on data rather than guesswork, providing confidence at every stage of the talent lifecycle.

Why It Stands Out:

• Backed by extensive academic and field research
• Used by leading employers, universities and government bodies
• Supports hiring, development, and academic screening

Measured Capabilities:

• Recognising assumptions
• Evaluating the strength of arguments
• Drawing logical and valid conclusions

Watson-Glaser evaluates a candidate’s ability to think critically through a structured model known as RED—Recognise Assumptions, Evaluate Arguments, and Draw Conclusions. These components provide a comprehensive understanding of how someone processes information and navigates complex issues.

This assessment is ideal for decision-making roles and programs that demand strategic thinking and analytical skills. Whether you are recruiting future leaders, selecting university candidates, or developing internal talent, Watson-Glaser delivers the insights you need to identify high-potential individuals.

Best Suited For:

• Graduate recruitment and university selection
• Leadership and professional role hiring
• Talent development and succession planning

Designed for flexibility and scalability, the Watson-Glaser assessment is available online or in paper format, across multiple languages.

Assessment Overview:

• Duration: 30-minute timed or untimed version
• Languages: UK/US English, French, Spanish, Dutch and more

Each participant receives a comprehensive report outlining overall performance and individual scores for the core components of critical thinking. These insights allow hiring managers and educators to understand where development may be needed and where strengths lie.

Included in the Report:

• Sub-scores for assumptions, arguments and conclusions
• Insightful feedback for hiring or coaching

The My Potentia Recruitment Report provides hiring managers with a clear, data-driven insight into a candidate’s potential, capability, and trainability—regardless of their language, literacy, or educational background. The report highlights key strengths, areas for development, and alignment to specific roles or training pathways.
