Admissions Welcome

We welcome your interest in Washington International School.

The strength and vitality of our School is the diversity of cultural backgrounds, talents, life experiences, and personalities of our students and faculty. One quarter of our students and their families are all American citizens, while an almost equal number are all non-US citizens; the remaining families are composed of members with more than one citizenship.

Our curriculum embraces an international approach to learning for students, beginning with the International Baccalaureate (IB) Primary Years Program for students from Preschool through Grade 5. In Grades 6-10 students continue with a multidisciplinary and inquiry-based approach designed to enhance understanding and develop the skills and knowledge needed to succeed in the prestigious IB Diploma Program (DP).

The multicultural educational experience is coupled with an emphasis on second-language acquisition, beginning with French or Spanish language immersion for our Preschool, Pre-Kindergarten, and Kindergarten students and continuing with a dual language approach for students in Grades 1-5; language options for older students vary based on ability and previous experience.

Students thrive in this lively mix of cultures, traditions, and ideas. We encourage them to take full advantage of the opportunities available to them in academics, and also in athletics, community service and other extracurricular activities. By mastering challenges both in and beyond the classroom, our students acquire the skills and experience to succeed on every level, and they form friendships that will last for years.

We hope you will tour the WIS website for information on all of our programs and for an introduction to our distinctive community of learning. We look forward to welcoming you for a campus tour soon.
