What do I need to prove my English proficiency?

Due to the admission regulations, students may only be admitted if they have the English language certificate of at least level B2 according to the Common European Framework of Reference for Languages. English certificates must be handed in as officially notarized copies. Online versions - like, for example, the TOEFL “Test taker report” will not be accepted. Please carefully read the official requirements of the University for English language certificates here.


- Students from a country with English as an official language;

- Students holding a German or Luxembourgish “Abitur” with at least 7 Years of English;

- Students holding a previous degree (BSc) which was taught entirely in English (must be mentioned in the official transcript).

What does an official certification look like?

An official certification can be provided by any public body or government agency with an official seal or stamp (Dienstsiegel). Examples are registration offices (Bürgerbüros) or the local registration offices of the State Residents’ Registration Office (Einwohnermeldeamt), as well as embassies, consulates and sworn translators if foreign academic records are to be certified. German notaries are also authorized to perform certifications. The institution (school, higher education institution) that originally issued the record in question can also certify a copy of that record.

Certifications issued by attorneys, certified auditors, associations, health insurance companies, and DAAD (German Academic Exchange Service) or from AStA (Allgemeiner Studierenden Ausschuss) are not recognized.

Every official certification must include at least:

1. Certification notice (this is a notice stating that the copy is as per the original);

2. Signature of the party certifying the document;

3. Official seal or stamp. (An official seal or stamp generally includes an emblem. A simple inked text stamp is not sufficient).

If the copy consists of several pages, proof must be provided showing that each page comes from the same document. It is sufficient if only one page bears the certification notice and signature if all pages are stacked up, stapled together, and stamped or sealed in such a way that a part of the official seal or stamp appears on each page (see below at the upper left-hand corner of the sample).

A sample certification
What if I do not have an engineering background?

For M.Sc. in SEE, the knowledge of an engineering bachelor’s graduate is assumed and required in most lectures. Our experience over the previous years showed that it is better to have this knowledge for students, so that they don't feel overwhelmed with additionally having to learn the fundamental engineering topics.

For students without a strong engineering background, we recommend checking out the certificate programs, especially: 'Crystalline Silicon Photovoltaics' and 'Solar Thermal Energy Technology'. These programs still have a bit of Physics, Mathematics and Engineering content, but could be handled by students without deep knowledge in those areas. The description of these programs can be found here.

What is the language of this program? Do I need to know German?

The courses are taught only in English. Participants may choose to write their master’s thesis in German or French after the University committee’s approval. Please carefully read the official requirements of the University for the English language certificate here.

When do I obtain my Uni-Account?

Once the Student Service Center finalizes your enrolment, you will receive a system-generated email from the University IT department (RZ= Rechenzentrum) with your personal Uni-Account and a single-use password with a link to „myAccount“.

Please change your password on this platform and inform our IT support Daniel Sassiat (daniel.sassiat@rz.uni-freiburg.de) about this. He will then modify your Uni-Account as the last step. Afterwards, the account is fully usable (including VPN).
