The International School of Ahafo is a day school and is open to all Newmont Ghana Ahafo Mine families and children of full-time teachers at ISA. It welcomes all age-appropriate children. Students moving to MKV are accepted throughout the year, although entry at the beginning of terms is encouraged, where possible. For non-MKV students, there is a selection process. This involves written assessments in English and Mathematics and an interview with parents and the student. For non-MKV families, the times to apply will be advertised through Newmont. Nursery is open only to MKV families. ISA welcomes applications from all age-appropriate children.

Children will be placed in the correct class for their age unless there are compelling academic or social reasons for doing otherwise, in which case parents will be invited to discuss the situation. Please note that lack of fluency in English is not regarded at ISA as a compelling academic reason for placing a child in a younger class. Children learn powerfully from their friends and will do so more effectively through daily interaction with children who are approximately their own age. Our year placement takes into account the academic and social development of the students. We believe students should be with children of a similar age, tackling tasks with the appropriate intellectual challenge.
