What is the SPRINT program?
Sophisticated Policy Research in No Time! (patent pending)
In brief, it's the structured approach we use in the lab. It is all about doing research in small teams of students with faculty mentorship, designed around rapidly vetting the ideas at the outset, followed by a 12-week timeline and frequent team meetings to keep it all on track. It builds community and produces papers!
Each project kicks off with a "paper sprint," pioneered at the University of Michigan. This interactive team meeting pieces together each researcher's study ideas and utilizes the team's collective insights to more quickly draft key pieces of the paper.
