The aim of the study is to describe the national accreditation preparation experience in higher education through the sample of a Faculty of Theology affiliated to a state university. The case study, one of the qualitative research designs, was used in the research. A total of three people experiencing the accreditation process in a state university were determined as the working group. In the research, the participants stated that the accreditation studies have beneficial effects for the institutions and education. They also emphasised that they had difficulties in obtaining the documents during the accreditation preparation phase and that the uncertainty brought about by the new process was challenging. It was pointed out that the accreditation studies would keep the institutions dynamic and carry the quality to advanced levels.
