This report describes the approach that REL Northeast and Islands (REL-NEI) used to guide its eight research alliances toward collaboratively identifying a shared research agenda. A key feature of their approach was a two-workshop series, during which alliance members created a set of research questions on a shared topic of education policy and/or practice. This report explains how REL-NEI conceptualized and organized the workshops, planned the logistics, overcame geographic distance among alliance members, developed and used materials (including modifications for different audiences and for a virtual platform), and created a formal research agenda after the workshops. The report includes links to access the materials used for the workshops, including facilitator and participant guides and slide decks.
