In this draft policy briefing on partnership we explain the GRNPP experience of managing international research coalitions. Richard Axelby, Emma Crewe, Jas Kaur and Bethel Worku-Dix outline how we have been managing grant-making, partnership and evaluation since 2017. We also offer principles and practical recommendations about how to engage in ethical grant-making and partnership. Evidence that our approach works can be found on our partners’ research pages and in this output library. We would love you comments, suggestions and critique by the end of 2020 – please send them to email@example.com. We will finalise this policy briefing in early 2021.
