The counselor has been very helpful in choosing classes my child is interested in. The technology program is current, with all new computers and software. The principal really administrates this school effectively. It is safe and there are zero "gangs" which can be find in other neighboring areas.

Middle and high school students also took subject-specific CSTs in math and science, depending on the course in which they were enrolled.
