Home - Assumption Catholic School

Welcome to Assumption Catholic School

When you walk through the door, you can feel it – the indescribable energy that comes from a place where every student is known, cared for and inspired to learn.

We hope you’ll visit us to experience that joy firsthand and hear from students, teachers and parents what it means to be a part of the Assumption Catholic School family!

Inclusive Community

Families of all faiths are welcome and EVERY CHILD is surrounded by Christ’s love!

Affordable and Accessible

ACS is the oldest private school in Bellingham, serving third and fourth-generation families of Whatcom County. One-fourth of families receive tuition assistance.

Committed to Service

To foster servant leadership, each grade level adopts a service project that they support throughout the year. Middle school students complete service hours as part of their Religion class requirement.

Rich in Diversity

Our school is more ethnically diverse than many schools in Whatcom County. Spanish is taught K-8. Cultures are honored and celebrated.
