2. Milo Adventist Academy

Location: Days Creek, Oregon (about 200 miles from Portland)

Grades: 9–12

Annual Boarding Fee: Estimated around $25,000–$30,000

Although not located directly in Portland, Milo Adventist Academy is one of the nearest alternative boarding options in Oregon.

What Makes a Great Boarding School

Before looking at the specific schools, it’s essential to understand what distinguishes an excellent boarding institution. The following factors often define the best schools:

  1. Strong Academic Reputation – A proven track record of high student achievement, Advanced Placement (AP) courses, or International Baccalaureate (IB) programs.

Key Factors to Consider Before Enrolling

When comparing boarding schools, always look beyond tuition figures. Consider the following essential elements:
