Oregon’s #1 Charter School

Since 2010, Arco Iris Spanish Immersion School (Arco Iris) has been steadfast in our mission to provide a robust academic program with Spanish immersion to grow the bilingual and biliterate leaders of tomorrow. Along the way, word of our small tuition-free public school has gotten out and earned us the title of Oregon’s #1 charter school from Niche. 


What makes us the best? Niche says our incredible test scores are part of the equation, and we agree, but we also know the answer lies deeper than the data. Our success as a school is  greater than the sum of its parts: our shared commitment to high-quality teaching and learning for all K-5 students in the Beaverton metro area creates a bit of magic that is hard to define, but easy to spot.  

#1 Charter School in Oregon

Niche aims to make the school choice process easier by providing website users with data, reviews and insights into schools nationwide. In their review of Arco Iris, we have received an A grade for our exceptional staff and academics. 


This score is based on our latest Oregon state testing, which reveals that 69% of students meet or exceed the benchmark in math and 82% of our students meet or exceed the benchmark in reading


These phenomenal stats are a reflection of our rigorous academic program that provides a rich, immersive Spanish language experience in a true multicultural setting alongside Singapore Math and a day that is dedicated to growing the whole child. Our teachers go above and beyond to meet students where they are and help them get where they need to go.

Happy Students, Happy Teachers, Happy Families

Beyond the numbers, we know Arco Iris is a pretty special place to be. It’s evident in the smiles of our students, the willingness of our families to volunteer, and the dedication of our staff to provide the best learning possible for our students. 


According to Niche, 80% of students and parents agree that the teachers genuinely care about the students. Here’s what parents have to say:


The teachers and staff are not only fantastic, but they create a wonderful learning environment, and strive to get to know each and every child. The Arco family - teachers, admin, students, and families - is one of a kind! There is a true sense of community and support.

My kids are excited to go to school each day. It is fantastic watching my children grow and thrive and become more fluent everyday as they learn to speak the language. 

-Arco Iris Parent


Niche has ranked Arco Iris in the top 10% of charter schools nationally–an impressive stat for a little school born out of a community’s desire to do what is best for children. The unity of our community creates a school environment that cannot be replicated! If you are ready to be a part of something exceptional, we invite you to enroll for Fall 2023
