The Collaboration has established a number of core groups, special interest groups and communities of practice to provide expert advice, support its strategic aspirations, while enabling professional development and experiential exchange.
| Core Groups | Special Interest Groups and Communities of Practice |

All subgroups are assigned a Steering Group Sponsor, to provide further support, insight and communication. New groups may be periodically proposed, and all subgroups are subject to Steering Group review if their activities fall below expected levels.
