US graduate entry exams not a predictor of PhD success, says study

Exams that US students need to take before being allowed into graduate school are not a reliable way of assessing whether those candidates will successfully complete a PhD. That is the claim of new research, which shows that the over-reliance on the Graduate Record Examination (GRE) in PhD admissions also discriminates against under-represented groups. The study has been carried out by a team led by Casey Miller - a physicist from the Rochester Institute of Technology - who analysed data for almost 4000 students who entered physics PhD programmes between 2000 and 2010, representing around 13% of doctoral enrolments during that period.
