    River Registration Day

    Headwaters School is thrilled to host our River Campus Registration Day event on Saturday, May 16. New to Headwaters River Campus Families are cordially invited to campus for this exciting event as we prepare for the 2026-2027 school year. 

    Registration Day is designed to be more than just a logistical process—it’s an opportunity to welcome new students and families, ensure a smooth transition from Admissions to Administration, and showcase the vibrant academic and extracurricular offerings at our River Campus.

    At this event, you and your student will have the opportunity to:
    • Complete Math and Spanish Placement Assessments (if applicable) to ensure proper course placement. 
    • Experience Our School’s Traditions and be welcomed into the community.
    • Explore Academic & Extracurricular Opportunities by learning about electives, arts, athletics, and student programs that shape our school culture.
    • Connect with Fellow Students and Families to build relationships with new and returning community members.
    • Meet with School Leaders and Faculty, including Directors, Advisors, and Guides who will support your journey. 
    If your student does not need one or both assessments, we still invite you to stop by anytime during the event to get introduced to our campus administrators, visit with staff, and meet other families!

    Invite to come!
