As reported at the blog:
- "The researchers found cognitive tests strongly predicted employees’ work and training performance, across all different job types investigated: clerical, engineer, professional, driver, operator, manager and sales. Both general mental ability tests and more specific tests (e.g. perceptual tests) predicted job performance. There was a tendency for the tests to be stronger predictors of performance for more complex jobs. The authors said: “Practitioners may believe, and indeed may have experienced, that such tests are less popular for senior appointments due to a misbelieve that they lack job-related validity; the results of our meta-analysis on a large sample of UK occupational groups strongly refutes this erroneous belief”.
