The Mercer Island school district consistently receives top scores on the Washington Assessment of Student Learning (WASL).  Twenty to thirty percent more Mercer Island's students meet the test standards than in the state overall.  98% graduation rate and 90% continue to higher learning.

Education generates significant interest in the district, with the PTSA and the Mercer Island Schools Foundation each raising hundreds of thousands of dollars each year for school-enrichment programs.  The non-profit Fine Arts Advisory Council, which showcases art and music at each grade level in an annual exhibition, supports the arts as core curriculum in each school.

An open-door policy allows all students to take honors and AP classes.

Alternative Program:  Crest Learning Center.

Funding: A four-year, $4.79 million capital-projects levy for facilities and technology improvements passed in 2004.  A four-year, $37 million operations levy and a one-year $400,000 school transportation levy passed in 2006.  More recently a $39.5 million dollar budget was passed for the 2008-2009 school year.
