As well as measuring levels of critical thinking ability-a skill required for success in numerous job roles—Watson-Glaser is also a good predictor of how someone will perform in many jobs and, as a result, the test is widely used around the globe.


Watson-Glaser measures an individual’s ability to:

  • Analyze, interpret, and draw logical conclusions from written information. 
  • Recognize assumptions from facts.
  • Evaluate the strength of arguments.
  • Draw correct inferences.

Research also demonstrates a correlation of Watson-Glaser test scores with creative thinking ability.
Watson-Glaser is used primarily as a timed assessment, in the context of recruitment, to measure critical thinking ability levels for job applicants. It is also used untimed in professional
development programs and interventions, or when reasonable adjustments are needed during recruitment.

  • New bank of business-relevant questions suitable for international use
  • Suitable for unsupervised (unproctored) screening of job applicants—questions are randomly selected from a large pool and no two individuals receive the same test
  • It is also suitable for online completion in a supervised environment such as assessment or development centers

In the Profile Report, an overall percentile score is presented with individual percentile scores for the three sub-areas of measurement: Recognize Assumptions, Evaluate Arguments, and Draw Conclusions. In addition to an overall percentile score, T-STANINE, and STEN scores are also reported.
