The AGRS selection process involves rose trials in multiple regional test gardens throughout the U.S.
In 2012, representatives from many professional rose organizations came together during "the Great Rosarians of the World" lecture series being held in New York City.
They discussed the establishment of a new, more rigorous national rose trial program, one that would identify and recommend the best roses to gardeners who lived in different regions in the U.S.[1] The group decided that the new rose trial test program should more selective than the previous AARS testing program, and require stricter maintenance standards for the AGRS test gardens.

One of the primary goals of the program is the selection of rose varieties that are disease resistant and easy to care for.
