Helping Students to Succeed – The Long-Term Effects of Soft Commitments and Reminders

To study whether a soft commitment device can help students succeed, we conduct a randomized field experiment and follow a cohort of tertiary students over six years. Students can commit to following their recommended study program structure, and they receive reminders each semester. This easily implementable, low-cost intervention is highly effective: it increases the five-year graduation rate (+15 percentage points) and reduces time to graduation (-0.42 semesters), driven by reduced dropout and an increase in credits obtained per semester. The effects are stronger for suspected procrastinators. A treatment only reminding students to follow the program structure has limited effects.
