Our Lab School: The Arbor School of Arts & Sciences

Arbor School of Arts & Sciences is a non-profit, independent elementary school serving grades K-8 on a 20-acre campus in Tualatin, OR. Low student-teacher ratios and mixed-age class groupings that keep children with the same teacher for two years support each child as an individual and foster a sense of belonging and community. An Arbor education means active engagement in learning, concrete experiences, and interdisciplinary work. For more information on the Arbor philosophy, please visit
