The newly released Pearson Efficacy Report details the scientific rigor and validation process that went into creating this assessment. Learn how and why the Watson-Glaser III is fair, valid and reliable, and why it is the gold-standard critical thinking assessment on the market.
The Watson-Glaser Critical Thinking Appraisal is a verbal ability test measuring critical thinking ability. It is considered to be the industry standard measure of critical thinking ability. It assesses an individual’s ability to analyse, interpret, and draw logical conclusions from written information.
In this efficacy report, we look at the evidence informing the design as well as the reliability, validity, and fairness of the Watson-Glaser III. In addition, the way an assessment is implemented has as much influence on its efficacy as its design, so profiles of implementation of existing users are included.
