This article presents data from an ethnographic study focused on the school engagement of Puerto Rican girls. I explore the school engagement of Puerto Rican girls through the metaphor of "passing". The findings demonstrate that despite variation between individual girls in academic achievement, all of the girls in the study suffered negative consequences from the limited ways that school engagement was constructed at their school. I argue that to understand and address the opportunity and achievement gap between Puerto Rican girls and other students, we must pay close attention to how this group of students is passing their time at school and to what passes as school engagement.
