“…The rest of the literature on differential prediction bias across African Americans and Caucasians stems from group-administered tests, for example, the SATs, used to assess college success (e.g., Bridgeman, McCamley-Jenkins, & Ervin, 2000; Centra, Linn, & Parry, 1970; Clearly, 1968; Cowen & Fiori, 1991; Jensen, 1980; Mattern & Patterson, 2013; Maxey & Sawyer, 1981); and a plethora of studies comes from employment testing and the armed forces (e.g., see summary of studies in Jensen, 1980, chapter 10; Sackett, Schmitt, Ellingson, & Kablin, 2001). With the exception of Mattern and Patterson (2013), who detected an overprediction in the slope of African American and Hispanic college GPA in their large sample of 475,000 students, results from predictive validity studies generally demonstrated no bias either in the magnitude of the correlation or in the slope.…”
