Understanding Washington International School Tuition Fees
Washington International School (WIS) is a coeducational day school located in Washington, DC, offering a challenging international curriculum and a rich language program for approximately 900 students from Preschool through Grade 12. WIS is known for its commitment to developing independent, critical thinkers and engaged global citizens. A significant aspect for families considering WIS is understanding the tuition fees and financial aid opportunities.
An Overview of Washington International School
WIS caters to students from Preschool through Grade 12, employing a unique educational approach at each level. Students in Preschool through Grade 5 follow the International Baccalaureate (IB) Primary Years Program (PYP). In Grades 6-10, students pursue a course of study designed to build skills in key areas while enhancing their ability to think deeply and solve problems. In their final two years of high school, all students are enrolled in IB Diploma Program courses.
The school is also a Project Zero site, teaching teachers in the area, so the pedagogy of the teaching is strong and well-respected in education circles. WIS distinguishes itself by allowing kids to be individuals so long as they are respectful and socially appropriate; and the biggest donors or the most affluent families are not given specialized treatment.

The School intends to offer aid to every accepted student who demonstrates financial need.
