International School of Portland is an independent private IB World School offering preschool through elementary education with language immersion in Spanish, Japanese, and Mandarin Chinese. The IB Primary Years Programme uses inquiry-based learning across core subjects through three immersion tracks - Spanish, Japanese, or Chinese, with English support as needed. The Spanish Track teaches the IB curriculum entirely in Spanish and culminates in a 5th-grade Capstone trip to a Spanish-speaking country, earning International Spanish Academy designation. The Japanese Track features native-level teachers and a Japanese-immersion IB curriculum, culminating in a 5th-grade Capstone Study Abroad trip to Japan; older students may complete Avant STAMP 4S and pursue Seals of Biliteracy. The Chinese Track is the longest-running immersion program in the region, with Mandarin-taught math, science, and social studies within the IB framework, culminating in a 5th-grade Capstone trip to a sister school in China. English instruction supports immersion learners and aligns with standards.
