Candidates who have completed undergraduate studies in theology at universities in Europe, Türkiye, or elsewhere may enroll in the Imam-Preacher Training and Development Course. Those who successfully complete the program receive certificates of authorization (ijazah) and are formally appointed as imams. After their appointment, imams continue to participate in regular training seminars throughout their service.

The Menar Institute supports theology students preparing to serve as imams, guiding their education and monitoring their progress. Before formal appointment, graduates undergo trial periods and advanced training. The Institute also organizes in-service seminars, develops specialized training programs, and establishes centers of expertise. In addition, it ensures that graduates who have completed hifz (memorization of the Qur’an) receive advanced training and certification. The Department of Religious Guidance coordinates the work of these institutions, reinforcing the infrastructure of training programs and expanding their scope.

In 2014, IGMG founded the Mainz Islamic Seminary to train its own imams. Since then, dozens of imams have graduated and gone on to serve in its mosques.
