The Graduate Common Room (GCR) refers to both the community of graduates at Christ Church, and its rooms. These are found at the top of the staircase in Tom 7 (see its location at College Maps). Most colleges use the term Middle Common Room (MCR) instead of Graduate Common Room but, as with many things, Christ Church does things differently! And awesomely. Hence, GCR it is.

Membership of the GCR is automatically given to anyone who has completed an undergraduate degree and is studying at Christ Church towards another degree. Associate membership can be granted to other individuals who may then make use of some of the GCR facilities. Partners of GCR Members are often made Associate Members, as are visiting graduates. Guests and visitors of GCR Members are also welcome to make use of the Common Room.
