About Us


Welcome from the Head of School


Dear Families,

Welcome to Willows Preparatory School! We are an IB World School, dedicated to offering an outstanding International Baccalaureate (IB) curriculum for children in Grades 5-12.

A key part of the mission of the IB is to prepare internationally minded students with a global worldview. This comes easily to our very diverse student population, whose families come from more than 35 different countries. Our school is part of the International Schools Partnership (ISP), and our students and teachers connect and collaborate with ISP schools all around the world. We are fully engaged in preparing caring and talented global citizens.

The IB curriculum is all about studying and understanding complex real-world problems, and our students engage daily in fun, exciting explorations of their environment and learn to develop and apply their mathematics, research, and analysis skills to authentic problem solving.

Our students are high achievers academically, with most working well above grade level. Additionally, our program ensures that our students are well-rounded, caring individuals. WPS students participate in a wide variety of arts, sports, and clubs, carry out community service projects, and find many ways to express their individuality.

I thank you for your interest in WPS and invite you to contact us with your inquiries. We look forward to speaking with you!

Matthew Lippart
Head of School


Our History

Bellevue Children’s Academy® (BCA®) was started as a tutoring center in 1992 by Yuka Shimizu. The success of the tutoring center led to the opening of BCA in September 1999 with nine students. By 2013 the school occupied three campuses in Bellevue, offering programs for Pre-Kindergarten to Grade 8. In early 2014, Bellevue Children’s Academy purchased the 15-acre site of Washington Cathedral Church in nearby Redmond. BCA relocated the middle school to the new site and was branded Willows Preparatory School (WPS®). The popularity of the middle school led to the development of a high school on the same campus. WPS’s first graduating class will be in 2023!

In 2015, BCA® began working to have  International Baccalaureate® (IB) accreditation. BCA® and WPS® are now accredited for  Primary Years Programme, Middle Years Programme, and Diploma Years Programme.

WPS is a proud member of the International Schools Partnership® (ISP®), a consortium of 50 international schools of choice recognized across local communities and the global education sector for amazing learning, ambition, and growth.
