This is the sixth report in a series tracking curricula discovery, selection, and adoption processes in U.S. K-12 education. The surveys have tracked the growth of digital materials and open educational resources (OER) in K-12 classrooms since 2017, providing trends on adoption and sentiments. This survey was conducted in April 2025, with a total of 1,137 teachers participating. The respondents come from 50 states and the District of Columbia. The key takeaways from this year's survey are: (1) While instruction remains overwhelmingly in-person, print and digital classroom materials are both integrated into classrooms; (2) Teacher satisfaction with classroom materials remains mixed; the majority of materials are given good to passable grades, with no difference based on the format that is used, but there is room for improvement; (3) OER awareness continues to grow, albeit slowly, matched by a small increase in OER adoption in the classroom; and (4) Grade level matters: teachers in higher grades are more likely to offer digital textbooks, though they are also more likely to use print materials, and much more likely to be aware of OER.
