The BIS Partnership

Bosomtwe International School (BIS), formerly Bosomtwe Commnunity School, is a low fee paying private school in the Ashanti region in Ghana. In the past 10 years, thanks to the support of the ZIS community, the school has grown from 20 children being taught in a small wooden hut to 135 students attending a purpose-built modern school campus. The school is governed by the proprietor, and ZIS teacher, Ibrahim Oubda. The "Ibrahim Oubda Education Foundation" is a registered charitable foundation in Ghana. BIS is driven by the mission - Respect, Knowledge, Independence.

What is the BIS Partnership?

  • The BIS partnership is an ongoing commitment to a mutually beneficial educational project between the communities of ZIS and BIS
  • ZIS provides continued financial support with a long term goal of establishing a self-sustaining financial model for the operational cost of BIS
  • ZIS provides strategic thinking and educational support, including faculty / administrator visits and faculty summer work placements
  • ZIS teachers, students, families and alumni benefit from the experience of direct service opportunities at BIS
  • The partnership is an all-school project uniting the four ZIS campuses and providing a focus for student (see the student-led BIS website) and community action
