The Kalamazoo Promise has led to a pronounced shift in the college-going patterns of Kalamazoo Public Schools (KPS) students who attend the Kalamazoo Area Math and Science Center (KAMSC). Following the introduction of the Kalamazoo Promise in 2005, the percentage of KPS KAMSC students attending public, in-state institutions of higher education has almost doubled—a shift that reflects the program rules of the Promise, which covers tuition and fees only at public postsecondary institutions in Michigan. The percentage of non-KPS KAMSC students attending an in-state, public institution also rose in the post-2006 period but only very slightly, suggesting that the Promise has shifted college choices among the eligible student population.
