数十年的研究评估了进入社区大学对获得学士学位的影响。在这项研究中，我们研究了方法选择（包括样本限制和识别策略）对 1970 年至 2017 年间发表的研究的估计效果的影响。在系统回顾文献后，我们利用荟萃分析来评估平均估计值并检查调节因素的作用。在我们的首选模型中，与进入四年制大学相比，进入社区大学与获得学士学位的概率平均降低 23 个百分点。在过去三十年中，影响的规模似乎有所扩大，尽管这与上大学人口的大幅变化同时发生。方法学的选择，特别是研究人员如何定义治疗组，解释了不同研究中估计值的一些差异。最后我们讨论了对未来调查和政策的影响。
Decades of research have estimated the effect of entering a community college on bachelor’s degree attainment. In this study, we examined the influence of methodological choices, including sample restrictions and identification strategies, on estimated effects from studies published between 1970 and 2017. After systematically reviewing the literature, we leveraged meta-analysis to assess average estimates and examine the role of moderators. In our preferred model, entering a community college was associated with a 23-percentage-point decrease in the probability of baccalaureate attainment, on average, compared with entering a four-year college. The size of effects appeared to grow over the past three decades, though this coincides with substantial shifts in the college-going population. Methodological choices, particularly how researchers define the treatment group, explain some variation in estimates across studies. We conclude with a discussion of the implications for future inquiry and for policy.
