Making the Grade (But Not Disclosing It) : How Withholding Grades Affects Student Behavior and Employment

We study the effects of grade non-disclosure (GND) policies implemented within MBA programs at highly ranked business schools. GND precludes students from revealing their grades and grade point averages (GPAs) to employers. In the labor market, we find that GND weakens the positive relation between GPA and employer desirability. During the MBA program, we find that GND reduces students' academic effort within courses by approximately 4.9%, relative to comparable students not subject to the policy. Consistent with our model, in which abilities are potentially correlated and students can substitute effort towards other activities in order to signal GPA-related ability, students participate in more extracurricular activities and enroll in more difficult courses under GND. Finally, we show that students' tenure with their first employers after graduation decreases following GND
