Some, but not all, private high schools require an admission process involving interviews and applications. At a minimum, many of those who are in grade six and above need to meet with an admission representative.
If an interview is involved in the admissions process, it typically lasts for about 45 minutes and focuses on evaluating the academic potential of the student. In addition, the interviewer looks at strengths in other areas such as art, athletics, service and leadership. All of this is done to ensure the school is a good fit for the student, as different schools have different philosophies on education. For instance, a student focused on achieving the highest grade point average may not thrive in a school that focuses on the arts.
