This article presents an exploratory case study examining the effects of different early college credit programs on time to baccalaureate degree attainment at a metropolitan Midwestern United States land grant university. We developed a Cox proportional hazards regression model of a students’ time to degree attainment as a function of their participation in different early college credit programs while controlling for each student’s preenrollment grade point average (GPA), American College Test (ACT) test score, gender, part or full-time enrollment status, ethnicity, and seasonal (Fall, Spring, or Summer) semester of initial matriculation. The most noteworthy finding of our analysis was that each early college credit program appeared to have a positive and statistically significant impact on reducing the time to degree attainment with all other factors being equal. However, the mechanisms through which these programs affect the time to degree attainment appeared to be differentiated by program.

早期大学学分计划对学生的成功产生积极影响

本文介绍了一个探索性案例研究，研究不同的早期大学学分计划对美国中西部城市土地授予大学获得学士学位的时间的影响。我们开发了一个 Cox 比例风险回归模型，将学生获得学位的时间作为他们参与不同早期大学学分课程的函数，同时控制每个学生的入学前平均绩点 (GPA)、美国大学考试 (ACT) 考试成绩、性别、非全日制或全日制入学状态、种族和季节性（秋季、春季或夏季）入学的学期。我们分析中最值得注意的发现是，在所有其他因素相同的情况下，每个早期的大学学分计划似乎对缩短获得学位的时间产生了积极且具有统计学意义的影响。然而，这些项目影响学位获得时间的机制似乎因项目而异。
