ISD – Internationales Sprachzentrum Dialogo

ISD, the Internationales Sprachzentrum Dialogo, is an international language school located at Habsburgerstrasse 83 in the 79104 district of Freiburg. The school specialises in intensive German courses for adults, with all programmes running five days per week and each day consisting of four 45-minute lessons. The minimum course duration is two weeks, and students typically enrol for longer periods to achieve meaningful language progress.

German courses

The school's approach is built on intensive daily instruction combined with practical language use in everyday contexts. German courses are taught by experienced native-speaking teachers who use modern communicative methods to develop all four language skills.

ISD Freiburg provides a focused, professional learning environment with small class sizes that allow for individual attention. The school also offers German courses for professionals who need industry-specific vocabulary and communication skills.

The regular intensive course usually runs on weekday mornings. Lessons are generally held at the Raustraße teaching centre. The school also uses Habsburgerstraße for some classes, and individual and two-person tuition can take place at either address.
