Trillium Charter School is a public TK-5 elementary school in Arcata, CA.  

Our school consists of combination classes with credentialed teachers and part-time paraprofessionals in each class. We are proud to maintain a very low staff to student ratio for core academics.  

We offer before and after school care for working families and participate in the national school lunch program, including free or reduced meals for eligible students.
