Abstract

Purpose: This study examines how undergraduate business student grades changed before, during, and after the COVID-19 pandemic using a large institutional dataset from a business college in a US university between 2015 and 2024.

Method: The analysis includes over 390,000 student-course observations and incorporates instructional modality, student demographics, course characteristics, and prior academic performance.

Results: Results show a substantial increase in mean course grades during the COVID-19 period, followed by a partial reversion post-pandemic to levels that remain above pre-pandemic trends. These patterns are consistent across modalities, demographics, and departments.

Implications: The findings raise important questions regarding the interpretation of grades as measures of learning and highlight the need for business schools to reconsider assessment practices in increasingly hybrid learning environments.
