How does your school support individual students’ learning needs?
The one-to-one model enables teachers to engage unique student interests and provides them with the opportunity to develop and articulate their own thoughts, interests, and opinions.
What extracurricular activities do you offer?
Headlands facilitates international and local group service trips as well as student lunch clubs in which students explore shared interests, such as leadership, yearbook, social justice, board games and more.
