Promise programs, or place-based tuition-free college policies, have become increasingly popular among policymakers looking to expand postsecondary attainment. In this article, we examine Tulsa Achieves, a widespread, albeit understudied type of promise program that covers the balance of students’ tuition and fees after other aid is exhausted at a single community college. Utilizing a difference-in-differences and event-study design, we investigate the role Tulsa Achieves eligibility plays in promoting or hindering vertical transfer and bachelor's degree attainment across racial/ethnic groups. We find that Tulsa Achieves eligibility is associated with increases in bachelor's degree attainment within 5 years among Native American and Hispanic students and an increased likelihood of transfer within 4 years for Hispanic students.

承诺计划或基于地点的免学费大学政策在寻求扩大中学后教育程度的决策者中越来越受欢迎。在本文中，我们研究了Tulsa Achieves，这是一种广泛的，尽管未被充分研究的承诺计划，它涵盖了在一所社区大学中用尽其他援助之后学生的学费和杂费余额。利用差异差异和事件研究设计，我们调查了塔尔萨取得资格在促进或阻碍种族/族裔群体的垂直转移和学士学位获得方面所起的作用。我们发现，塔尔萨人达到资格与美国原住民和西班牙裔学生在5年内获得学士学位的增加以及西班牙裔学生在4年内获得转学的可能性增加相关。
