Winterim
March 12-19, 2026
Winterim experiences take place over the six class days before spring vacation each year and reflect an intentional time set aside in the OES Upper School for experiential and immersive education to allow students hands-on opportunities to explore and understand the world outside the walls of a traditional classroom. Our courses explore an array of topics, locations, and ideas, in and around our local Portland area, domestically across the United States, and internationally in varying locations each school year. Our international courses are rooted in building global competence and intercultural learning opportunities, while our domestic and local courses encourage students to cultivate their curiosity and reach beyond what is familiar by leaning into our inquiry-based learning cycle of exploring, creating, connecting, committing, and reflecting. Additionally, all of our Winterim courses integrate the Learning for Justice Social Justice Standards, just as we have integrated these into our classroom curriculums.
Winterim has a rich history at OES, and we are excited to build on an incredibly successful year last year. In 2026, students will have the opportunity to travel to six different countries through our international offerings, while faculty and student-proposed domestic and local courses will provide many opportunities closer to home. Across all courses, students and faculty learn side by side as part of our vibrant school community.
Winterim participation is required for graduation, so families should not schedule outside travel during this time.

Travel Documents
Each student traveller will need a valid passport for international travel. Some students may also require an additional travel visa for the destination country that they are placed in. It is the responsibility of parents/guardians to obtain all required travel documents for their student. Copies of all travel documents will need to be submitted to the US Main Office 30 days before departure.
Additional Cost and Financial Assistance
OES offers need-based financial support for Winterim courses. Any Upper School family may apply for financial assistance toward any Winterim course (local, domestic, or international), regardless of whether they pay full tuition or receive financial aid toward their OES tuition. While the majority of Winterim courses require no additional cost to families, international and domestic courses do require further financial commitment for transportation, accommodations, meals, activities, and rentals. The cost of courses will be included in the course catalog so you can make an informed decision when registering.
It is our goal to enable students to participate in one international and one domestic Winterim course during their time in the Upper School. Families that have not submitted a Clarity application for 2025-26 will be asked to submit tax documents along with their Winterim financial assistance application. The supplemental aid committee of financial aid will prioritize funding to students who have not already participated in an international or domestic Winterim course. Domestic Winterim courses are considered courses that travel outside of Oregon. Please note: In order to be eligible for Winterim financial assistance, a family’s account should be in good standing with the business office.
If you have further questions about the financial assistance program for Winterim, please contact financialaid@oes.edu directly.
