History
History
BBIS began on 2 October 1990 when the application for state registration was accepted, just before Germany's reunification process was complete. It opened as the International School Berlin-Potsdam (ISBP) and welcomed eight students on 16 September 1991 in a rented villa, before expanding to a second Potsdam facility in 1994. In 1998 Berlin-Potsdam International School GmbH was established as a non-profit company. After relocating to Kleinmachnow and a series of campus improvements, the school renamed BBIS Berlin Brandenburg International School on 1 September 2002 to reflect its Brandenburg support and broader geographic reach. Major milestones included purchasing the Seeberg site in December 2005, opening a boarding facility in 2008 (which moved onto the campus in 2010), and refurbishments such as House 5 in 2021 and the new Primary Centre beside House 1 in 2022.
