In educational development, accountability is paramount, in particular for activities that take educational developers away from their institutional boundaries to local, national, and international venues. Educational developers must demonstrate the benefits of such work to the home institution and its constituents. We asked educational developers from around the world to comment on the nature and value of their external work. Their responses made clear that such work expands valuable social networks and, concomitantly, builds social capital. Using these observations, we explain how social network analysis can be used to assess and demonstrate the impact of external work.
