New Student Digital Device Set-Up
Admissions
HNA has specific requirements for setting up each student's device, whether PC-based or Mac. We have found that it is beneficial for your daughter to participate in the setup process—it will make her more comfortable with her device when she starts school in August. Setup should require one to two hours, depending on your home Internet speed.
While setup is not complicated, some students may feel more comfortable with a little assistance—which HNA will offer exclusively for new students on two different dates this summer at the school.
Tuesday, August 18, 2026, 5:00 PM – 6:30 PM.
