We reviewed the literature on "noncognitive" predictors-specifically, personality as it pertains to graduate education. The review is divided into 3 sections. In the first section, we reviewed measures typically used in studies of graduate school outcomes, such as attrition and time to degree. We also reviewed which student qualities faculty and administrators said they desired and cultivated in graduate programs. We also noted that there are many qualities faculty ranked high in desirability but which could only imperfectly be gleaned from sources such as letters of recommendation and personal statements. In the second section, we reviewed general personality factors (e.g., the "Big Five"), specifically, definitions, measures, correlates, and the validity of those measures. We concluded with a discussion of how personality factors might be used in admissions and guidance applications for graduate education.
