Board of Directors
GISSV is a California nonprofit organization governed by a Board of Directors comprised of GISSV parent volunteers. Elected by its Society, the Board legally represents GISSV, while also establishing the strategic direction for the school. The Board consists of 11 members, each of whom is elected to serve a term of three years. Members of the Board can be elected for up to three three-year terms with a two-year break in services after the second term. The Board holds regular meetings to perform its duties as specified in the GISSV by-laws (Approved by the Society in May 2016; pending approval from Germany) and in accordance with the Board-adopted Business Rules and Code of Conduct.
Organizational matters are regulated and approved by the Board in coordination with the Head of School. On behalf of the GISSV Board, the Head of School is responsible for the daily management of the school. The GISSV Head of School as well as a representative of the German Consulate General in San Francisco attend Board meetings as non-voting members.
Upon resolution of the Board, additional persons may participate in an advisory capacity during Board meetings, or may be consulted on individual topics on the agenda. Typical guests are the Head of School, the Head of Administration and the Parent Association (PA) presidents or their representatives. The PA presidents present parent issues as discussed at PA meetings for consideration by the Board.
