The Trustees of the GLSC are leaders of the private German language schools and have many years of practical experience. They are elected annually and select among themselves the officers of the Organization. They are educated at German and/or US universities and hold advanced degrees. They are professionally as well as personally committed to the mission of the GLSC and perform their duties on a pro bono publico basis.

In order to execute their duties in the service to the German Language School Conference, the Trustees meet monthly (approximately ten times a year) to discuss business matters of the German Language School Conference as well as requests and questions from individual schools, their teachers and parents. If necessary, additional meetings may be convened. The President will send out an agenda three days prior to the meeting. The GLSC member schools are informed about regular meetings in advance. They are kept abreast of the proceedings of all GLSC meetings and of all general or specific matters concerning German language schools by the minutes and/or follow-up phone calls.
