The active operational phase of the project is the SDSS-IV, which began on July 1, 2014 and is planned to run until 2020.
The SDSS-IV collaboration is still growing and continues to actively recruit new institutional partners. For more information about joining SDSS-IV, see the Joining Document and the Principles of Operation below.
The SDSS-IV Advisory Council is the collaboration’s governing body, formulating recommendations on project scope and budget to the Board of Governors of the Astrophysical Research Consortium (ARC), which has responsibility for all activities at Apache Point Observatory. Collaboration policies are developed and implemented by the SDSS Collaboration Council (CoCo), which has a representative from all of the full and associate institutional partners. The CoCo is chaired by the SDSS Spokesperson, who is elected by the collaboration for a 3-year term.
For more detailed information about the SDSS collaboration, and how it operates, please see the important policy documents below.
More detailed implementation policies, most importantly the Publication Policy and the External Collaborator Policy, are developed by the CoCo and approved by the Advisory Council.
The three main collaboration policies used within the SDSS projects are described below.

Survey Science Teams & Working Groups
Each of the individual surveys has its own Survey Science Team (SST), which acts as the highest level of working group for science associated with that survey.
Additional information on SSTs and WGs can be found here.
As described in the PoO and the Publication Policy, all science projects using non-public SDSS data must be announced to the Collaboration via the project-list web page when they are initiated. At a level above these individual projects, which will typically encompass one or several papers led by a few active team members, scientists may wish to collaborate and coordinate in larger groupings and thus create a “working group” (WG) for the sharing of common knowledge, facilities and information.
