Doctorate education at the Twente Graduate School gives students an opportunity to immerse themselves in high-impact research projects across a variety of disciplines and to benefit from close interactions with world-class researchers and teachers.

The Twente Graduate School is a breeding ground for research talent. It sets high standards. There is a rigorous selection for the research and educational programmes. We want to retain talent for the university in an early stage by offering prospective, talented, motivated students a special, high quality educational experience. This applies to our own university's talent in general, and to international talent in particular.

  • Mission of Twente Graduate School

    The mission of Twente Graduate School (TGS) is to train and educate excellent researchers, usually at the start of their career, and to present and promote excellent research via clustered or separate doctoral programmes. The doctoral candidates are trained to prove their competence by means of a doctoral thesis. With this mission, the TGS aims to improve the quality of research and education, to accentuate the University's identity and profile and to differentiate and individualise the specific doctoral programmes and services for its participants.
