There are also tourist programs like:
One could make arrangements to participate in German language classes beyond the tour.
There are also academic programs. Students who want to study in Germany should ask the faculty of their current theological school for recommendations. Here are a few theological schools who have formal arrangements with theological schools in Germany. Again, one could pursue an intensive German language learning program with exposure to German theological education.

Germany. The Collegium Oecumenicum in northern Munich, Germany, offers Lutheran School of Theology at Chicago (LSTC) students the chance to live and study for up to a year among a community of 50 students from Germany and other parts of the world. Students do their academic work at the University of Munich. Students may register for the winter semester (November to February) and/or the summer semester (May to August).
Duke Divinity School's Reinhard Huetter used to be involved with this.
Candler School of Theology "has ongoing exchange programs with Göttingen University in Germany."
An exchange program is in place between Duke Divinity School and the Protestant Faculty of the University of Erlangen, Germany. This exchange brings one Erlangen student to Duke and sends one Duke student to Erlangen every year . . . Individual students from time to time have made private arrangements for study abroad. This study has most often taken place in England or Scotland, with academic credit usually transferable toward the Duke degree.
What other travel abroad programs do you know that combine German language acquisition and exposure to theology?
