Best kept secret in Delaware! Great environment for high school students. Teachers are great Christian role models and challenge kids to be responsible and work to the best of their abilities. My other two sons attended St. Marks and were well prepared for college and beyond. There are plenty of ways to get involved from sports, the arts and clubs. Students are very inclusive. Never heard of any bullying. Great school!
Review St. Mark's High School
I graduated many years ago so I'm not sure what has changed, but I was heavily involved in theatre band and chorus. The school made me choose to go into theater for a living. When in college, there was no other high school that could compare with the curriculum when I talked to other students. I've been working in Atlantic City for 32 years now.
I have found the teachers to be excellent but there are gaps in the administrative skill levels. Often decisions are made that seem not to be thoroughly thought out, but if you bring a question to the admin they are responsive. The students seem to love their teachers but not have the same level of high regard for the admin, especially the Asst. Principal!
