“…General mental ability (GMA) tests are one of the most valid construct-based predictors of job performance and training success. Thousands of validity studies and many meta-analyses have shown that they are excellent predictors of different organizational criteria, such as supervisory ratings, work sample tests, job knowledge acquisition, grades, production records, instructor ratings, promotions, sales, and wages, and that the correlation between GMA and performance appears to be similar across jobs that differ considerably in content (Schmidt and Hunter, 1998; Murphy, 2002; Ones et al, 2012; Schmitt, 2014; Salgado, 2017a; Berges et al, 2018; Rodríguez and López-Basterra, 2018). Furthermore, the theoretical foundations of GMA are stronger than for any other personnel selection measure (Schmidt and Hunter, 1998; Hunt, 2011; Deary, 2012; Salgado, 2017a).…”
