Cohesion and solidarity include a conscious approach to diversity - this characterizes the Clausthal spirit. We work in partnership on the challenges of a sustainable society under the thematic umbrella of the circular economy.
We take our social mission seriously.
Good science is our mission. Transfer and dialog with politics, business and society is a central concern for us. We are an international university with a global scientific impact and at the same time make an active contribution to the development of the region.
We stand up for unity and freedom of research and teaching.
We place high demands on the quality of research and teaching, which can only develop in unity and freedom. We exercise this freedom responsibly. Outstanding achievements in research and teaching are held in the highest esteem at our university and are actively encouraged.
We promote the development of skills and personality.
We are the starting point and destination for students and researchers from all over the world. We take into account and integrate the diversity of our members to ensure openness to the world, creativity and equal treatment. In this environment, we enable a holistic, scientific education. This includes both the acquisition of academic skills and the development and unfolding of personality for individual career and life paths. Competence and personality characterize our alumni, with whom we remain connected in many ways.
We learn and teach in future-oriented and quality-assured degree programs.
For quality assurance and the further development of our degree programmes, we draw on instruments of university didactics, digitalization, quality management and evaluation. In this way, we gain insights into teaching and learning and incorporate them into the design of teaching and learning processes.
We are committed to our research profile.
We focus our research content and resources on our research fields, taking into account the guiding theme of the circular economy and constantly developing our profile in the areas of energy - materials - information. Outstanding scientific achievements in basic and application-oriented research are equally highly recognized by us. We work in an interdisciplinary manner on systemic approaches to the technical challenges of a sustainable society. We review the relevance of our research through publication and exchange at national and international level, thereby generating a high level of visibility in the scientific community.
We bridge the gap between fundamental findings and practical applications.
The practical orientation of our research and the implementation of our findings are our strength. Our application-oriented basic research provides the scientific basis for transfer to industry and society. We establish long-term networks and collaborations with science, industry and society based on mutual trust. We are committed to a high degree of transparency and neutrality.
We research, learn and teach with mutual respect and a high level of commitment.
We research, learn and teach transparently and openly in mutual appreciation of the knowledge and experience of all those involved. We work together across disciplinary and hierarchical boundaries. We see the diversity and manageability of our university as added value.

We are a universitas - a community.
Together we are TU Clausthal.
Clausthal University of Technology has been one of the most international universities in Germany for many years. This is due, on the one hand, to the high proportion of international students (more than half) and, on the other hand, to the international composition of the academic staff. Globalization is not only taught but also lived on campus, in lecture halls and laboratories, in student dormitories, and at joint celebrations and events.
Research, teaching, and transfer work in an interdisciplinary manner on the major social challenge of securing the sustainable supply of resources for society in the age of incipient climate change and advancing the energy transition. The focus is on systemic approaches to realizing the circular economy.
Clausthal University of Technology is a key economic force and major employer in its region. It closely connects research with industry, bridging theory and application. With a strong focus on the circular economy, the university promotes resource efficiency, sustainability, and innovation, supporting solutions for climate change and digital transformation.
Foreign applicants must hold a secondary school leaving certificate to be eligible for admission to Clausthal University of Technology.
Direct University Admission
If the foreign certificate is recognized as equivalent to a German certificate, the applicant can be directly admitted to the degree program—after passing a recognized German language exam such as DSH-2 or DSH-3, TestDaF (TDN 4), or an equivalent.
Applicants whose secondary school certificate is not equivalent may still receive direct admission to Clausthal University of Technology if they can prove successful completion of one or two years of university study in their home country. The exact requirement depends on their country of origin and prior education.
Admission via the Studienkolleg (Preparatory College)
Applicants whose qualification is only partially comparable to a German one must pass an assessment test at a Studienkolleg before starting their degree. The preparatory college for all universities in Lower Saxony is located at Leibniz Universität Hannover. A two-semester preparatory course is offered to help students prepare for this test. Participation requires passing an entrance exam. Application and registration for the Studienkolleg are handled by Clausthal University of Technology, where your application documents must be submitted.
Requirements for the Studienkolleg Entrance Test Invitation
Studienkolleg Hannover has updated the requirements for participating in the entrance test.
Prerequisites:

Establishment of the Mining Schools
At the end of the 18th century, the Upper Harz region was one of the most important ore-mining districts in Europe. Half of the silver mined in Germany came from Clausthal and the surrounding area. To further develop mining, training was to be improved. From 1775 onwards, 24 young miners and smelter workers we... read more
2006– 2018: Research centers become established
Markets are becoming more global, and tasks more complex. Science is increasingly organizing itself across disciplines. At Clausthal University of Technology, this is leading to the establishment of interdisciplinary, industry-oriented research centers. Energy, materials, and simulation are the focus areas of these centers. Environmental technology, drilling technology, and digitalization have been added.
2015:
All-time high with 4963 students
Shortly after German reunification, more than 4,000 young people studied in Clausthal, but this number dropped to 2,400 by the turn of the millennium. A modernized range of courses, marketing efforts, and broader societal developments led to a steady increase in student numbers. In the winter semester of 2015/16, the highest enrollment in the more than 240-year history of higher education in Clausthal was reached: 4,963 students.
2020:
TU Clausthal – the University of the Circular Economy
The world's population is surpassing eight billion. At the same time, the consumption of raw materials, energy, water, and land is increasing. To counteract climate change and conserve resources, a fundamental shift in thinking is required. The linear economic system must be transformed into a holistic circular economy. Therefore,
