In 1992, several Christian mission organizations saw the need for a school in Central Europe to serve missionary families in the region. On September 19, 1994, ICSB opened its doors for the first time, with 56 students in grades 1 through 12, and 21 faculty and staff members. In the spring of 1997, our first full class of seniors graduated from ICSB and began attending colleges in North America.
In 1998, ICSB received full accreditation from the Association of Christian Schools International (ACSI) and Middle States Association of Colleges and Schools (MSA), which it still maintains. Over the past decade, ICSB has grown to approximately 250 students in Kindergarten-12, with over 100 faculty and staff members.
