Due to the generous support from our constituency and alumni base, annual giving has doubled over the past three years, which helps support our tuition assistance programs.

Beginning with our current sophomore class (Class of 2025), we transitioned from family-purchased iPads to school-issued laptops. A $250 technology fee, which covers the devices, software, insurance and all other related expenses has been included into the tuition for Grade 9-10. There will be the opportunity, per the final terms of our provider, for students to keep their devices upon graduation as well. Please note, transfer students in grades 11-12 are required to purchase their own iPad. The following iPads suffice: iPad 7th generation or 8th generation, iPad Air 3rd or 4th generation or an iPad Pro 3rd or 4th generation.
