Increased time to college degree completion increases tuition and foregone earnings costs. Encouraging college students to take more semester credits is a low-cost way to reduce time to completion. We implemented an experimental informational intervention to increase student course loads by varying the intensity of information about the benefits of taking 15 credits per semester. We find no effect of our treatment on students’ course loads. Our null finding is of interest because of the increasing popularity of low-cost informational interventions. Uncovering null results like these is important for the design of future interventions.
