a private school in Tualatin

K–8 · Private · Preparatory · Progressive

4201 SW Borland Rd, Tualatin · Isaac Enloe, Head of School

Arbor School offers a progressive education that blends rigorous academics with creativity, collaboration, and critical thinking. Thematic, mixed-age studios weave literature circles, design-tech, Socratic math talks and forest ecology into multi-week projects that culminate in public exhibitions.

Teachers act as facilitators, guiding students toward deep understanding through discussion, experimentation, and reflection. The curriculum prioritizes empathy, ethical reasoning, and problem-solving, with an emphasis on process as much as product. This environment encourages students to see connections between disciplines and to approach learning as an active, joyful endeavor.
