What it is
The APS (Akademische Prüfstelle) verifies academic documents for applicants from certain countries. The office, procedure, and whether a certificate is required depend on where your qualifications were earned and the route you are using.
Why it matters
Where required, an APS certificate is often needed before you can apply to universities or for a visa. Missing it can block your application, so check early whether your country has an APS requirement.
