Until

The annual Enrollment Verification Process (EVP) for the 2026-27 school year opens August 7 and must be completed by August 14. The process is completed online via Family Access (Skyward) and is required for each student, every year.

 

The EVP allows families to confirm their student’s enrollment, update emergency contact information and complete required forms regarding health and other topics.

 

The reason we ask families to complete EVP for every student every year is that this critical information helps us accurately plan for staffing and resources for our schools and departments.

Meet Principal Erin McKee!

Hi, Falcon families! My favorite part of being a principal is greeting our students each morning. A few fun facts about me: If I could only eat one cuisine for the rest of my life, it would be Japanese food. My bucket list includes attending a Beyoncé concert. I’m really good at parallel parking.
