The development of cultures of support has become important in programmes for the preparation of research students. The paper draws on in-depth interviews with 21 research education coordinators from Australian and United Kingdom institutions to identify the strategies that they use to build research cultures and integrate research students into them. Students' research cultures are not always linked to departmental research cultures more generally. Local contexts and conditions and staff (including supervisors') attitudes are found to be critical in how research education coordinators respond and what is considered possible in order to ensure that research students are involved in research cultures.
