The Kalamazoo Promise (KPromise) is amongst the most well-known and generous tuition-free policies. This study advances the understanding of Promise student performance and persistence. We used a weighted-least square means and variance adjusted (WLSMV) SEM approach and k-nearest neighbors (k-NN) to deal with missing data. The main model suggested first-year college GPA (β = –.48) possessed the strongest effect on a first-year stop out followed by socioeconomic advantage (β = –.26), high school performance (β = –.25), immediate enrollment (β = –.22), and KPromise funding (β =.06). Model differences from 06–10 and 11–15 cohorts, illustrate that in the later cohorts socioeconomic advantage’s effect on a first-year stop out lessened.

Kalamazoo Promise (KPromise) 是最著名和最慷慨的免学费政策之一。这项研究增进了对 Promise 学生表现和坚持的理解。我们使用加权最小二乘均值和方差调整 (WLSMV) SEM 方法和 k 最近邻 (k-NN) 来处理缺失数据。主要模型表明，大学一年级 GPA (β = –.48) 对第一年停止的影响最大，其次是社会经济优势 (β = –.26)、高中成绩 (β = –.25)、立即注册 (β = –.22) 和 KPromise 资助 (β =.06)。06-10 和 11-15 队列的模型差异表明，在较晚的队列中，社会经济优势对第一年止损的影响减弱。
