Based on meta-analysis results, cognitive ability tests appear to be among the most valid of all psychological tests and are valid for most occupations. However, these tests tend to do better at predicting training criteria than long term job performance. Cognitive ability tests in general provide the benefit of being generalizable. Hence they can be used across organizations and jobs and have been shown to produce large economic gains for companies that use them (Gatewood & Feild, 1998; Heneman et al., 2000).
