Asian Americans are the most highly educated racial group in the United States and are commonly heralded as the model minority for their high academic success. Nevertheless, previous research suggests that Asian Americans may face certain disadvantages in school settings. For example, Asian Americans' academic advantage over non-Hispanic white students diminishes between kindergarten entry and the next several years of schooling. This study provides a closer examination of the educational progress of Asian American students compared to white students through a seasonal comparison approach. Using the Northwest Evaluation Association, we analyze reading and math scores for over 130,000 Asian American and white students in grades K-7 in approximately 675 public schools across the US. We find that Asian Americans have higher academic achievement than white students in general, but that these advantages are maintained primarily through faster rates of learning during the summer months. When school is in session, the Asian advantage either remains unchanged or shrinks, consistent with the view that some school processes undermine the educational progress of Asian American students relative to white students.
