GGNB is administered by the GGNB board, which includes the speakers of all doctoral programs and (if not already included among the speakers) one representative of each participating institution. The board takes all pertinent decisions and elects a speaker for a (renewable) 3-year term. The GGNB board is assisted by the GGNB office as a central management and service unit, which provides administrative support to the doctoral programs in matters including assessment of the eligibility of applicants for admission, monitoring training activities and scheduled thesis committee meetings, administration of the doctoral exams, and management of finances.
An international scientific advisory board evaluates GGNB biennially. In addition, measures of quality assurance include student evaluation and feedback on all training activities, annual surveys among students and faculty, and the monitoring of the students’ performance (publications, grades etc.) of each program by the GGNB board. Each program prepares an annual report that forms the basis for the internal evaluation.
GGNB is anchored in the Georg August University School of Science (GAUSS) which is the degree-awarding body for all doctoral students of the mathematics and natural science faculties. GAUSS defines the general regulations for all graduate schools and programs in mathematics and natural sciences, and formally approves all ordinary faculty members and each of the doctoral programs.
