There is no institution officially known as "Cambridge International College" that is accredited in Ghana. Cambridge International Examinations (CIE) offers a curriculum and examinations, but it's not an institution itself that grants degrees or diplomas directly. Schools in Ghana might *use* the Cambridge curriculum, but that doesn't mean the school itself is a "Cambridge International College."
If you're considering a school or institution claiming to be affiliated with Cambridge in Ghana, you need to verify its accreditation with the National Accreditation Board (NAB) of Ghana. Only the NAB can confirm if a particular institution is legally authorized to operate and award qualifications in Ghana.
