American colleges and universities make great promises of mobility but consistently fail to deliver on them. This reneging hurts us all, but most perniciously, it leaves thousands of low-income, first-generation (LIFG) students in debt and without a degree. Nationally, there is an almost 2-to-1 difference in who graduates from college. Only 40% of LIFG students who enter a four-year college graduate in six years, compared to 78% of higher-income, continuing-generation (HICG) students. And worse, this rate hasn’t budged in decades. Two groups of universities defy this broad pattern of failure: the Ivy Elites and the Equity Engines. The Elites garner the majority of public and scholarly attention despite serving a tiny number of LIFG students with endowments that rival the wealth of small nations. The Equity Engines are their mirror opposite: they admit large numbers of LIFG students and graduate them at high rates despite great budgetary constraint. But even in the wake of these extraordinary accomplishments, they remain largely invisible in the public imagination and scholarly discourse.

This oversight is not by accident. In the United States, universities that prioritize inclusivity and equity over exclusivity and prestige are penalized rather than rewarded, both in terms of status and resources. But we ignore these institutions at our own peril, for Equity Engines are storehouses of vital wisdom about what it takes to reduce social inequality in higher education. Keeping the Promise provides a systematic examination of the people and practices that power equity-driving universities and the external pressures that undermine their work. By centering the duality of these unique universities—as both powerful, agentic, local campuses, and precarious organizations under constraints—I offer critical new insights into student success, organizational creativity, and how to transform American higher education to promote a more democratic and equitable society.
