School Overview
Riverdale High School, located in the Dunthorpe neighborhood of Portland, Oregon, is a small, public high school that operates as part of the independent Riverdale School District. Renowned for its intimate academic environment, the school maintains a rigorous, college-preparatory curriculum that emphasizes critical thinking, small class sizes, and strong student-teacher relationships. Because of its size, the school fosters a tight-knit community where students are encouraged to engage deeply in both their academic pursuits and extracurricular activities.

The school is well-regarded for its focus on liberal arts and its unique "one-room schoolhouse" philosophy that carries over into its high school culture, promoting individualized attention and a high level of accountability. Riverdale draws students not only from its local district but also through a popular open-enrollment/transfer program, which attracts families seeking an alternative to the larger comprehensive high schools found in the surrounding districts. With a campus situated near the scenic Terwilliger corridor, the school provides a quiet, focused setting that balances traditional academic excellence with modern, inquiry-based learning methods.
