Sixteen years ago, the Kalamazoo Promise went into effect guaranteeing full college scholarships to eligible graduates of the Kalamazoo Public Schools (KPS) district. The Kalamazoo Promise provided the model for a unique type of college scholarship program, one in which the allocation of funds is based not on merit or need, but on place--specifically, Kalamazoo, a medium-sized midwestern city located halfway between Chicago and Detroit. The Kalamazoo Promise is perhaps one of the best designed "place-based" scholarship programs in the country. The scholarship is flexible, allowing recipients to access funds any time within 10 years of graduation. The scholarship is universal: every graduate of KPS is eligible for a Promise scholarship provided they have been enrolled in and resided within the district for a minimum of four years, with the amount of the scholarship increasing based on enrollment length. As of 2022, the Kalamazoo Promise has been in effect for over 16 years, with close to 10,000 KPS students using the scholarship. The goals of the Kalamazoo Promise were immense and daring; to lower the cost of postsecondary education and increase incentives for high school graduation, college attendance, and college completion. The Kalamazoo Promise has succeeded in many ways, although time is still needed to understand the full impact of the scholarship. In honor of the Kalamazoo Promise's "sweet 16," this report presents 16 key findings from 16 years studying the Kalamazoo Promise.
