WHY WIS? 

Our mission is to be an exemplary learning community—enriched by differences, informed through inquiry, global in reach.

Since 1966, Washington International School has offered a rigorous, immersive international education in Northwest DC. Students begin in full language immersion, continue in dual-language English and French or Spanish through the IB Primary Years Programme, and can add Mandarin from Grade 6 on the path to the IB Diploma. Our Primary campus (Age 3–Grade 5) sits between Georgetown and Glover Park, and our Tregaron campus in Cleveland Park is home to Middle and Upper School. We'd love for you to join us.
