In this article, I utilize a regression discontinuity design to estimate the effects of Tulsa Achieves—a prevalent and understudied type of tuition-free college program. In contrast to concerns regarding tuition-free community college suppressing bachelor’s degree attainment, I find that Tulsa Achieves increased the likelihood of transferring to 4-year colleges by 13 to 14 percentage points and increased bachelor’s degree attainment by approximately 2 percentage points. The estimates for shorter outcomes are underpowered to detect policy relevant effects, but suggest Tulsa Achieves increased college GPA and had a null impact on credit accumulation, retention, and graduation from Tulsa Community College.

在本文中，我利用回归不连续性设计来评估Tulsa Achieves（一种普遍且未被充分研究的免学费大学课程）的影响。与对免学费的社区大学抑制学士学位获得学位的担忧形成对比，我发现塔尔萨成就学院将转入四年制大学的可能性提高了13％至14个百分点，而学士学位获得率则提高了大约2个百分点。较短结果的估计不足以检测政策的相关影响，但表明塔尔萨大学的GPA有所提高，并且对学分积累，保留和从塔尔萨社区学院毕业的影响不大。
