International Application Process

Hillside is currently accepting applications for grades 4 through 9.

Thank you for your interest in Hillside School. We are delighted that you are considering Hillside School for your son and we hope you find this process as easy and as accessible as possible.

The first step towards admission consideration is to fill out an online INQUIRE NOW form and provide us with some basic information. Please note, all of the information you enter in the inquiry will pre-populate the application form.

Once you complete the INQUIRE NOW form, your email address (once activated) will give you access to our Parent Portal. After completing the inquiry form, a member of our Admission team will let you know your email is now active and you may now access the Parent Portal to create your password. After creating your password, you can log into the Parent Portal to complete the Application Checklist of items (highlighted below). All of these steps will be completed directly online through the Parent Portal.

Application Process

To apply to Hillside School, please complete all of the steps listed below. Completion of all Application Materials will be submitted electronically through the Parent Portal with your email address and password.

In order for our non-English speaking students to experience the maximum immersion into our English speaking community and American culture, we only offer a 5-day or 7-day boarding program. We do not offer a day student option for non-English speaking students.

All prospective families must complete an Application for Admission, and submit the application fee.
