As of my last knowledge update in January 2022, several German language proficiency exams are recognized globally, and some of them may be available in India. Here are a few examples:
Goethe-Zertifikat Exams: The Goethe-Institut, a German cultural association, offers a series of language proficiency exams known as Goethe-Zertifikat. These exams assess different levels of proficiency, ranging from A1 to C2. The exams cover listening, reading, writing, and speaking skills.

TestDaF (Test Deutsch als Fremdsprache): TestDaF is a standardized test for the German language and is often required for admission to German universities. It assesses language skills at the advanced level and is accepted by many educational institutions in Germany.

Telc Exams: The telc GmbH provides language tests, including German language exams at various levels. These exams are recognized by educational institutions and employers in Germany and beyond.

ÖSD (Österreichisches Sprachdiplom Deutsch): ÖSD is an Austrian organization that offers German language exams. Their exams are recognized internationally and cover various proficiency levels.

To get the most accurate and up-to-date information about German language exams in India, it is recommended to check with the official websites of language institutions, cultural organizations, or language centers that offer German language courses. Additionally, you can contact the Goethe-Institut centers in India or other language institutes that specialize in German language education. They should be able to provide information on available exams, test dates, and registration procedures.
