Your school profile can list the number of students in each stream (or academy, as you wish to call them) and highlight it’s a low attrition school, meaning either it is supportive and tries to lead all admitted students through the Senior WASSCE, or that its entrance is selective, ie., all Junior 3/9th graders can’t automatically assume they’ll get to continue in 10th at your school and most who start in 10th are supposed to be able to keep up.
