If you’re thinking about taking a German proficiency exam, and have a passing score recognized by the German government, company, or university, you MUST sign the “Declaration of Consent” form. You will NOT be allowed to even sit for the exam if you do not.
The Goethe-Institu e.V. is a part of the German government. Your data is never allowed to enter the “free market.”
What concerned me is that the “Declaration of Consent” has two parts to it. On the one hand, they want to be allowed to use your data, which must include exam scores, for “market research, advertising, and any marketing associated with the range of services offered by the Exam Center and the Goethe Institute…” The next paragraph basically says that they will store and archive your test data for 10 years.
It’s a bit confusing, and I guess I overreacted when I read the form. But you won’t be allowed to sit for an exam unless you sign.
On another note, you are permitted to revoke your consent at any time.
