Arco Iris Spanish Immersion Charter School, Oregon’s top-rated tuition-free bilingual public charter school, is planning to open a new location in Tigard!That means more families, more bilingual learners, and more of the award-winning Spanish immersion education that has made Arco Iris one of the top charter schools in Oregon.

Arco Iris, Born From a Big Idea

In 2010, a group of parents and educators in Beaverton shared a belief: that every child deserves access to a rigorous, bilingual education, and that tuition shouldn't be the barrier. So they built Arco Iris from the ground up.

More than 15 years later, that idea has grown into one of Oregon's top-ranked charter schools, serving over 400 K-5 students in a vibrant multicultural community. Beaverton families have watched their children become bilingual, biliterate, and deeply prepared for whatever comes next. Now it's Tigard's turn!

Tigard Families: Here's What We Would Like To Bring To Your Community

If you live in Tigard and have been searching for a dedicated Spanish immersion education for your child, you already know the gap that exists. The area offers some bilingual options, but most split time evenly between Spanish and English, or house immersion as one track inside a larger school.

Arco Iris operates differently: Spanish immersion isn't a program within a school. It IS the school.

From the first day of Kindergarten, students learn in a fully immersive Spanish-language environment, with 80% of the school day happening in Spanish. That high percentage of Spanish instruction gives the language time to take root, building the deep fluency and cognitive foundation that makes true bilingualism possible, while still creating space for English to grow alongside it.

At Arco Iris, teachers come from across the Spanish-speaking world, bringing their languages, cultures, and traditions into every classroom. The curriculum pairs Oregon state standards with a rigorous Singapore Math program and a whole-child approach that builds biliteracy alongside confidence, curiosity, and cultural competence. Students don't just learn Spanish. They learn IN Spanish, and that distinction makes all the difference.

Why Arco Iris Stands Out

We get asked all the time what makes Arco Iris different. Here's the honest answer:

• Tuition-free, always. Arco Iris delivers private school quality without the price tag. Every family, regardless of income, gets access to a world-class bilingual education.
• Award-winning academics. Niche ranks us as a Top 10 Charter School in Oregon, and our students consistently exceed state benchmarks in both math and reading. Read our top 10 reasons families love Arco Iris to see what keeps them coming back year after year.
• Singapore Math. Our rigorous math curriculum develops deep number sense and problem-solving skills that go far beyond memorization, all taught in Spanish.
• A pathway to lifelong opportunity. Bilingual graduates enter the college admissions process with a distinct advantage and enter the workforce in even stronger standing. The skills students build at Arco Iris follow them for life.
• A true community. Arco Iris families don't just drop kids off and leave. They volunteer, they celebrate, they show up. This is a school where you belong.

What’s Next?

We open our Tigard campus to K-2 students in the first year, and we expand by one grade each year until we reach the 8th grade. That means families who enroll in Kindergarten will grow with this campus, helping shape its culture and community from the very beginning.

This is your chance to be a founding family!
