Superintendent Dr. Fred Rundle Welcome Message

What makes US The Right District For You?

Mercer Island School District thrives and maintains a high standard for student achievement in and out of the classroom. We emphasize three core tenets: amplify our message and promise of a dynamic education, elevate our systems and practices to deliver an exceptional education experience, and develop a school community that thrives. We strive to not only be recognized as the top school district in the state of Washington but also to be a point of pride for our community, staff, and students.

Upon graduation Mercer Island students are committed, motivated, and poised to succeed both in and out of the classroom, backed by our value of supporting the whole child.

The Best Thing About Math on Mercer Island

Special Services 

MISD Special Services programs serve students with disabilities from birth through twenty-one years who reside on Mercer Island. Students with disabilities are served in the least restrictive environment to the maximum extent possible. Thus, at all our schools, there are students with special needs participating as appropriate in general education classrooms and general education curriculum.

Special education services include individualized, specially-designed instruction in academic, self-help, communication, motor, vocational and social skill areas. Individual Education Programs (IEPs) are developed at least annually. IEP goals are written for each student based on the results of formal and informal testing and observations. Some student will also have objectives for each goal. The district carefully sequences instruction and maintains data about student progress.

Multilingual Learners

Multilingual/English learners will meet state standards and develop English language proficiency in an environment where language and cultural assets are recognized as valuable resources to learning. 

The Mercer Island School District provides limited English proficient parents with information in their own language so that they can make informed decisions about their children's education. This includes providing interpretation and translation services for vital meetings and communications.

More information can be found on the Multilingual Learners page on our website.

Mercer Island School District provides Learning Support Services (partially funded through state and federal funding). These services support readers in developing their skills to close any gaps in reading early. Specialists working with students are highly trained in the Science of Reading (SoR) and instructional strategies and techniques grounded in 50 years of research. 

Services provided to students who are identified may be provided in a pull out or push in model, depending on the school, grade, and students' needs. These services work to close any learning gaps quickly, so that students can read proficiently and find success in all grades and contents.

Critical Partners of the Mercer Island School District

Community Publications

Every January the Mercer Island School District publishes an Annual Report. You can read past Reports on our Annual Reports page. Annual Reports are mailed to all residents of Mercer Island and provided to District partners. 

At the beginning of every year MISD produces a School Profile for each of our six schools. These profiles, which reside on our School Profiles page, provide school administration contact information as well as how the school is implementing its School Improvement Plan (SIP).

Each school is required to present a SIP to the School Board annually in the first half of the school year. SIPs for the 2022-23 school year can be read on our SIP website.


The Mercer Island Schools Foundation (MISF) is a 501 (c) (3) public service, non-profit organization dedicated to enhancing and improving the quality of education provided to ALL MISD students by obtaining contributions for the public schools.

Started in 1981, the Foundation has raised over $26 million for our students thanks to our generous community. Since its founding, the Foundation has become the catalyst for the island community to guarantee every teacher has access to the most up-to-date, innovative educational materials that guarantee exceptional teaching and learning experiences for every student.

The tremendous success of the organization lies in the simple fact that MISF was born in a community that places value on quality education. Learn more about the impact of MISF’s commitment to education.


Mercer Island Youth and Family Services (MIYFS) licensed mental health counselors are a critical part of the learning environment in each school on the Island.

Counselors work collaboratively with students, families and school staff to support the social and emotional needs of students in every school, helping them build a strong foundation for their future.

We encourage all parents to reach out to your child’s MIYFS school counselor, just as you would their teacher, as they can be a valuable resource for helping your children thrive in school. 

Visit the MIYFS Website for a full description of the services provided by MIYFS at our elementary schools, middle school and high school.
