Achiase Senior High Programmes and Course

The school offers these following programmes

New pupils are admitted in September every year through a computerized system which is under the jurisdiction of the Ghana Education Service. The system works based on the results of an entry examination known as the Basic Education Certificate Examination (B.E.C.E). This examination is held for junior high schools at various centres throughout the country. Entry Forms for the above examination are obtained from the West African Examination Council (W.A.E.C) through the headteachers of the respective junior high schools within the country. Once the computerised selection process is completed, the list of admitted students are made available by the Ghana Education Service to the school. The list is then made public through the school’s notice board.

An opportunity is given to foreign nationals wish to apply for admission into the school through a written entrance examination organised by the school.

After a student gains admission, he is given the school's official prospectus. This book helps new students about the school and all that is required of them.
