The International School provides an engaging and rigorous academic program, taught primarily through a second language - Japanese, Chinese, or Spanish. With natively fluent teachers from around the world, children become bilingual in language and culture.

TIS has been an authorized IB World School since March 2010. It was the first school in the Pacific Northwest authorized to offer the IB Primary Years Programme (PYP).

The faculty and staff are the backbone of The International School.  They hail from all over the world, including Chile, Taiwan, Cuba, Japan, Mexico, China, and Spain. All TIS teachers are experienced and college-educated - often in their home countries. All teachers have native-level fluency of the language they teach, and they all love children!
