The implementation of the BGG is difficult to measure. The most obvious measure of its implementation is the progressing barrier-free accessibility in society.

In autumn 2016, for example, the Deutsche Bahn stated that 77% of the 5,400 railway stations operated by DB in Germany could be reached without stairs. 59% of the stations have an optimised platform height so that people with walking disabilities can board trains without assistance. 51% of the stations also have a guidance system for people with visual or hearing impairments.

However, a study by the University of Kassel, commissioned by the Federal Ministry of Labour and Social Affairs, found that the real weakness of the BGG is its lack of implementation and the fact that it is unknown to people with disabilities.
