Welcome to Greencastle-Antrim High School, an active, vibrant learning community for
students in grades nine through twelve.

It's a whole new world at this level as students continue to learn and grow and as they
begin to make preparations for life beyond high school.

We provide a wide range of educational experiences and guidance as we continue to put
Children First and expose each student to as many opportunities for their futures as we can.

As principal of Greencastle-Antrim High School, I am honored to work with our district’s students. They truly are top-notch and take full advantage of the variety of opportunities we offer. Many of our students earn college credits through our Early-to-College and College Academy programs. Others participate in internships through our School-to-Work program. Students seeking a career in a technical field will benefit from our GAHS STEAM Program, as well as our partnership with Career Tech (FCCTC). In addition, our students excel in music, arts and athletics, but most impressive, they truly display outstanding character, supporting one another through times of tragedy and times of triumph.

Fast Facts for the Class of 2020

  • 202 graduates were awarded diplomas
  • 71 students earned 459 college credits

Greencastle-Antrim High School is a special place. Everyone works together to extend educational opportunities for all of our students by providing educational programming tailored to students’ individual career interests. Children First…more than just a feel-good slogan, it’s a way of life here for our entire staff. G-A Proud!
