In March the Deutsches Sprachdiplom B1 and C1 are administered if there are eligible students. These exams provide the most advanced students an opportunity to demonstrate foreign language proficiency at the highest level. Some American universities recognize the Deutsches Sprachdiplom C1 by awarding college language credit and advanced placement. The Sprachdiplom C1 diploma is an official certificate accepted by all German universities, which will then waive any further language entrance testing.
