Declining Validity for MCAT

The Medical College Admission Test has generally been successful in predicting students’ success during medical school and residency training and on licensing exams, according to a study published in Academic Medicine. However, as the test has been changed over the years, validity has declined on part of the national medical licensing exam, the study found. Further, it found no correlation between MCAT scores and students’ clinical competence as residents because the “validity coefficients were either nonsignificant or practically negligible.”
