The Measurable Impact of Free Textbooks on College Graduation Rates

The rising cost of higher education is well documented, but one of the most persistent barriers to student success is a hidden fee handed out on the first day of class: the syllabus reading list. With the average undergraduate spending over $1,200 annually on textbooks and supplies, course materials have become a significant financial hurdle.[6]

For decades, the assumption was that expensive, commercially published textbooks were simply the cost of a quality education. But a growing body of academic research is upending that consensus. The data reveals that Open Educational Resources (OER)—freely accessible, openly licensed text and media—do not just save students money. They actively improve academic performance and keep vulnerable students from dropping out.[1][6]

Open Educational Resources are teaching, learning, and research materials that reside in the public domain or have been released under an intellectual property license that permits free use and repurposing. Unlike traditional textbooks, which are locked behind copyright and expensive access codes, OER can be downloaded, shared, and customized by professors to fit their exact curriculum.[3]

The immediate financial impact of OER adoption is staggering. When institutions coordinate their efforts, the savings scale rapidly. In Colorado, a state-funded OER grant program is projected to surpass $75 million in cumulative student savings by the spring of 2026. Similarly, the Achieving the Dream initiative, which tracked 38 community colleges, found that replacing commercial texts with open resources saved 160,000 students nearly $11 million over a two-and-a-half-year period.[3][4]

Yet, the most critical question for educators has always been one of efficacy: Does free mean lower quality? A comprehensive 2024 meta-analysis published in the International Journal of Educational Research examined 26 distinct studies to answer this. The researchers found that students in OER courses actually earned higher overall grades and had higher completion rates than their peers using commercial textbooks.[1]

The mechanism behind this improvement is not necessarily that open textbooks are inherently superior to commercial ones. Rather, the academic boost comes from universal, immediate access. In a traditional classroom, a significant percentage of students delay purchasing the textbook until their financial aid clears, or they attempt to navigate the course without it entirely. With OER, 100 percent of the class has the required reading on day one.[6]

This universal access acts as a powerful equity multiplier. A landmark study analyzing 21,822 students found that OER adoption significantly decreased DFW rates—the percentage of students who receive a D, an F, or Withdraw from a course.[2]

Crucially, the Colvard study revealed that these academic gains were not distributed evenly. The drop in DFW rates was disproportionately larger for Pell Grant recipients, part-time students, and historically underserved populations. By removing the financial barrier to entry, OER effectively narrows the attainment gap in higher education.[2]

The success of individual OER courses has led to the development of "Z-Degrees"—entire degree pathways where every required course has zero textbook costs. Several states now mandate that course catalogs clearly label OER sections, allowing savvy students to build their semester schedules based on which classes will not require expensive commercial materials.[3][4]

Despite the overwhelming evidence supporting OER, systemic adoption remains sluggish. A recent report by Bay View Analytics found that while 64 percent of higher education faculty are now familiar with open resources, only 29 percent actively require them in their courses.[5]

The primary bottleneck is not ideological, but logistical. Transitioning a course away from a commercial textbook takes significant effort. Professors report that planning an OER course initially takes twice as much time, as they must curate, review, and align disparate open materials to their learning objectives.[4][5]

Furthermore, commercial publishers provide a suite of ancillary materials—test banks, slide decks, and automated grading software—that save professors immense amounts of time. Without institutional support, such as course-release time or stipends to compensate for the extra labor, many faculty members simply cannot afford to make the switch.[5][6]

Even so, the faculty who do transition rarely look back. Surveys indicate that over 80 percent of professors who have taught with OER say they would not return to traditional commercial materials.[4]

As higher education faces mounting pressure to demonstrate its return on investment, the evidence surrounding OER offers a rare, unambiguous win. It is one of the few pedagogical interventions that simultaneously lowers the cost of attendance, improves academic outcomes, and advances institutional equity. The challenge for the next decade is no longer proving that OER works, but building the institutional infrastructure required to make it the default.[6]
