This report is the fourth in a series investigating K-12 curricula discovery, selection, and adoption processes in the U.S. This year's survey was conducted in April 2022 and provides insights into the beginning of the post-pandemic K-12 curricula in U.S. schools. The survey results come from K-12 administrators and teachers from 49 states and grades Pre-K through 12. While most K-12 schools had returned to in-person classes, teachers and administrators were still dealing with the effects of the COVID-19 pandemic. Changing federal, state, and local health guidelines for in-person instruction throughout the year meant that teaching styles were still in flux. One of the lasting impacts of the COVID-19 pandemic on K-12 education may be the increased adoption of digital tools in the classroom. While many aspects of education are reverting to pre-pandemic methods, this year's survey found that there has been an increased acceptance and expected use of digital curricula materials in the K-12 classroom. In addition to examining the curriculum adoption process, this study explores materials classified as open educational resources (OER). Some key findings from the survey include: (1) The 2021-22 school year represented a year in flux: students returned to the classroom, but pandemic restrictions created delays, impacting curricula adoption; (2) The majority of administrators still report that the pandemic has changed or impacted their course adoption process for the 2021-22 school year; (3) Looking forward to 2025, K-12 educators and administrators believe that digital materials are here to stay, albeit mixed with some physical materials; (4) Two-thirds of all teachers are unaware of OER at any level, and OER awareness has declined amongst K-12 teachers, when compared to previous school years; and (5) OER Awareness is higher for users of OER, but the majority of respondents using OER report being unaware of OER.
