The use of online homework systems that require the purchase of an access code has become widespread. The purpose of this study is to examine student experiences with and perceptions of online homework systems with access codes. Postsecondary students (N = 966) completed a survey about the financial costs, perceptions of quality, engagement with, and learning with online homework systems. Most students (79.5%) indicated that they had been required to purchase an access code for an online homework system. Of those who had been required to purchase an access code, 29.4% reported their grade was hurt because they could not afford an access code. Students reported online homework systems were moderately helpful for learning. When considering students who have been historically underserved by higher education, Black students reported more courses with required access codes for homework and reported that online homework systems were more helpful than other students. Latino/a/x students were more likely to report their grades were hurt by not affording access codes (47.9%) than other students. First-generation students reported they avoided courses with online homework systems (36.9%) more than continuing-generation students (23.9%). Overall, the findings indicate that the cost of online homework systems is a barrier to education, and alternatives should be further developed and promoted.
