In early 2021, an ORFG “stretch goal” working group designed the Open Access Funder Cohort program to recruit a small group of open access champions from different philanthropies (both ORFG members and beyond) and empower them to advance open access within their organizations. This first cohort included representatives from six philanthropies, the American Brain Tumor Association, Doris Duke Charitable Foundation, Esmée Fairbairn Foundation, Schmidt Futures (also an ORFG member), St. Baldrick’s Foundation, and TSC (Tuberous Sclerosis Complex) Alliance. The Health Research Alliance contributed to the socialization of the program, and four of its members signed on to the project. The program launched in August of 2021 and then met monthly, providing both structured curriculum and customized advising to empower representatives to advance open research within their organizations. The last group session was held in January of 2022 and then final 1:1 sessions were done with members to provide customized support, bring representatives closer to their policy goals, and wind down this first cycle. Building on the success of this pilot, the ORFG ran a second cycle of the program, with group sessions from October of 2022 to February of 2023 and 1:1 advising sessions through to early April. Participants were recruited from the Philanthropic Leaders Open Scholarship Cohort through the NASEM Roundtable on Aligning Incentives for Open Science. The second cycle encompassed a significantly larger cohort (20 funders), including the Advanced Education Research & Development Fund, The ALS Association, American Epilepsy Society, American Federation for Aging Research, Arnold and Mabel Beckman Foundation, Burroughs Wellcome Fund, CureSearch for Children's Cancer, Damon Runyon Cancer Research Foundation, Dana Foundation, Focused Ultrasound Foundation, Heising-Simons Foundation, John Templeton Foundation, LUNGevity Foundation, MacArthur Foundation, Pew Charitable Trusts, Rainwater Charitable Foundation, Rita Allen Foundation, Simons Foundation, the Sontag Foundation, and the Volkswagen Foundation. Based on feedback from the first pilot, the curriculum was expanded to explicitly go beyond open access and include a range of open scholarship practices, and thus the name of the program was changed to the Open Scholarship Policy Development Working Group. Herein are shared the curriculum, reading lists, and presentations that form the educational materials for the program. The primary materials can be found in the 2021-2022 folder, while the updated materials from the second cycle can be found in the 2022-2023 folder. All files are shared in both pdf and editable formats, such as docx and ppt. Files may lose some formatting in conversion, please see pdf files for the correct formatting. All materials are openly licensed to encourage reuse and remixing. While engagement is a crucial element of the program, some funders may not be able to participate in a cohort for various reasons. Public resources allow the ORFG to share information and strategies beyond the cohort and potentially broaden the impact of the program.
