B2 and C1: the two WiSo levels
WiSo says most of its master's programmes can be studied entirely in English or bilingually. Pages such as the Master Business Administration and Business Analytics and Econometrics ask for B2; the Master Economic Research asks for C1. The CEMS figures come from the CEMS declaration of English knowledge.
| Test | B2 master's (e.g. Business Administration) | C1 master's (e.g. Economic Research) | CEMS MIM (C1) |
|---|---|---|---|
| IELTS Academic | 5.5 | 7.0 | 7.0 |
| TOEFL iBT, new 1-6 scale | 4 | 5 | Not stated |
| TOEFL iBT, old 0-120 scale | 72 | 95 | 100, at least 20 per section |
| PTE Academic | Not listed | Not listed | 68 |
| Cambridge | B2 First, BEC Vantage, C1 Advanced, C2 Proficiency | C1 Advanced or BEC Higher (grade B+), C2 Proficiency | CAE or BEC Higher grade B+, CPE grade C+ |
| Duolingo English Test | Not listed | Not listed | Not listed |
IELTS Online, Indicator and One Skill Retake
On the WiSo programme pages, IELTS Indicator and IELTS Online are accepted in addition to the regular IELTS Academic test, and TOEFL iBT Home Edition and Paper Edition are accepted alongside the regular TOEFL. TOEFL and IELTS results are valid for two years; Cambridge certificates and degree-based proof have unlimited validity.
CEMS is stricter: it does not accept TOEFL MyBest Scores or IELTS Academic One Skill Retake, and only accepts results from specific test dates.
Outside WiSo, departments set their own scores. The MSc Computational Biology asks for upper B2: IELTS 6.5 with at least 6.0 in each component, or TOEFL iBT 93.

Take a free scored IELTS mock →Using an English-taught degree instead of a test
WiSo accepts a bachelor's or master's degree taught totally in English, with proof such as a Diploma Supplement or an official university letter confirming the programme was 100% in English. The pages do not limit this to particular countries, so an English-medium degree from India or Pakistan can count if the letter says so. For a bachelor double degree, at least one year must have been spent in an English-speaking country.
CEMS accepts an English-taught bachelor's only if it was issued in an English-speaking country, by a CEMS member or by an EQUIS/AACSB-accredited university.
German, deadlines and uni-assist
Some Business Administration specialisations, such as Accounting & Taxation, also require German at C1, unless your degree or school-leaving qualification was in German. All subject and language requirements must be met at the time of application, which runs from mid-April to 15 June through the KLIPS portal. Applicants with a bachelor's from outside Germany also need a preliminary review documentation (VPD) from uni-assist.
Requirements vary by programme and change between admissions cycles. The score that binds you is the one on your Cologne programme page and in your offer, so check it there before you book a test.
