Independent research, which will be published soon, highlights strong links between barrister training performance and Watson-Glaser scores.
In one study carried out in 2010, a correlation of .62 was found between scores on the 80 item version of the Watson-Glaser and average final exam grade, in a sample of 123 students.
This is a very high correlation coefficient, suggesting a strong link between barrister training success and the Watson-Glaser.
The final grade included written exams and ratings on vocational exercises such as writing opinions and arguing a case.
The table below highlights the average test score for each category of student on the course:

In a further study carried out in 2011, sampling 988 participants, a correlation between average final exam grade and scores on items from the Watson-Glaser Unsupervised of .52 was found.
Furthermore, the Watson-Glaser was more predictive than A level points, degree class and whether or not the student attended a Russell Group university.
These studies provide strong evidence in support of the tool’s usage in the law industry, in particular for barrister training selection. Following on from this, anyone wishing to train as a barrister will be required to complete the Bar Course Aptitude Test, which is composed of Watson-Glaser items. This test will be administered at Pearson Vue test centres and will be made available to candidates later this year.
Watson-Glaser is now available as an online test with a bank of items suitable for unsupervised testing. Many organisations are using it for their graduate programmes as a sifting tool.
Since introducing the Watson-Glaser at the early stages of assessment, one large international law firm has seen the percentage of graduate applicants not meeting the grade at the assessment centre fall from 25% to 6%, resulting in both a saving in partner time and the cost of assessment.
