The Watson-Glaser Critical Thinking Appraisal contains 80 item questions across a series of five test exercises and takes about 60 minutes to complete. Each item requires the application of analytic reasoning skills.
These skills need to be applied to statements reflecting everyday work and study situations and draw from content typically found in the media. The statements involve comment and assertions that require a degree of critical evaluation that would not ordinarily be accepted without question. The five exercises cover: 
-
Drawing Inferences
-
Recognising Assumptions
-
Argument Evaluation
-
Deductive Reasoning
-
Logical Interpretation.
Background to Watson Glaser
In the early part of the 20th century, Watson became interested in how it might be possible to measure fair-mindedness. In 1937, Glaser modified and revised Watson’s ideas for use in An Experiment in the Development of Critical Thinking. Since then the Watson-Glaser Critical Thinking Appraisal (WGCTA) has undergone many modifications and developments, including extensive internationalisation to take account of the now global market for such types of testing. WGCTA is now the most widely used psychometric test for the pre-selection and appraisal of managers in organisations of all types and sizes. Its international reputation, and its continued and widespread use means that WGCTA has very robust standardisation, reliability and validity making it one of the most trusted testing tools available.
Using Watson Glaser
-
Selection - At the point of entry into an organisation, Watson-Glaser can be used as part of the selection process to help make decisions that will maximise the talents of the individual against the needs of the organisation.
-
Talent Mangement - Watson-Glaser can be used as a powerful tool within a talent management programme, helping to identify hidden talent within an individual. Organisations demand highly developed critical thinking skills from their leaders and managers, and so it becomes more important to identify that capability early on.
-
Retention - Watson-Glaser is a useful measure to help inform retention schemes. For instance, in a call-centre where verbal reasoning skills are in high demand to ensure that both the operative and the customer get the best experience, Watson-Glaser can help to identify areas for development.
Reliability and Validity
Reliability of the Watson Glaser test has been determined in three ways. Estimates of the test’s internal consistency, stability of the test scores over time and the correlation between scores on alternate forms. Internal consistency was measured using split-half reliability coefficients using the Spearman-Brown formula. Testing stability over time, by administrating the test to the same group with an interval difference, indicate an acceptable level of stability. (0.73). Overall reliability estimates are sufficiently high to warrant use of the test for group administration and research studies.
The test conforms to British Psychological Society and American Psychological Association guidelines on personality test construction and use.
Accreditation Requirements
In order to receive the reports from the Watson-Glaser, a British Psychological Society (BPS) Level A accreditation is required. If this is not held Getfeedback can provide a qualified consultant to provide feedback.
We offer the Watson Glaser/RANRA combined test, allowing you to assess verbal and numerical abilities in one sitting.
Administration Options
Please note that in line with the test publisher’s guidelines for ability tests every possible step must be taken to ensure that the question sets are protected, and that the individuals completing the assessment are the individuals named. By purchasing this test you agree to ensure that everything possible is done to ensure this.
