Here are the Most Expensive High Schools in the PNW

The price of higher education has increased over the decades. Attending a College and a private high school in the Pacific Northwest can be expensive.

A new 2025 study from the Alot Education Publication revealed the most expensive high schools in every state.

Before we get to the most expensive private high schools in Washington, Oregon, Idaho, and Montana, here are the three most expensive private high schools in America.

3) New York’s THINK Global School in Manhattan charges students $94,050 to attend this year. Getting a degree from THINK Global means you’ll have studied in four countries for four years of high school.

2) Connecticut's Pinnacle School. The cost? $107,000 a year. The school emphasizes students who don’t thrive in the typical learning environment and helps them become college-ready.

1) The most pricey private high school in America, Valley View School in Massachusetts, asks for $125,000 annually. They’re an all-boys school that uses academics, athletics, the arts, and therapy to prepare young men for the high seas of life. 

The most expensive private high school in all 50 states, as reported by the Alot Education Publication, was based on tuition for the 2023-2024 school year. These figures reflect annual costs. Multiply that dollar amount by four to understand your investment in your child's high school education. If you think it's worth it, then you are more than correct!
