The Future

Chief Sealth International High School fosters global awareness and academic success through a challenging and engaging curriculum in a safe and supportive environment.

New International School Designation

Chief Sealth has had a long-standing commitment to academic excellence for all.  We have a rich tradition of diversity and are committed to programs that support students from all backgrounds.  Our International Baccalaureate courses have global, cultural, and ethnic perspectives, and we have several partnerships with organizations and schools in both Asia and South America.   Many of our staff bring to the classroom a deep cultural awareness gained from travel, study or their own heritage.  Our World Languages department is one of the strongest in the district and we offer four language options for students and often have pioneered new language offerings.  

In 2009, our school was designated as an international school. This designation has three important components:

  • Academic Excellence for All: Innovative and Culturally Competent Teaching and Learning 
  • Global, Cultural, and Ethnic Perspectives & Partnerships 
  • An Emphasis on World Languages 

Having this International School designation will open more doors for financial support and signals to business and government leaders our commitment to international education. 


International Baccalaureate

Chief Sealth High School is an accredited International Baccalaureate (IB) school entering its third year of full operation, offering IB courses and the full IB diploma program. In May, 2009, the first year that Sealth presented graduating seniors for exams, 57 students registered for 190 exams. Fourteen students attempted the full diploma, of which five received a diploma. Fifty six % of the students passed their chosen IB assessments and received IB certificates. 

In the current senior class (2010), 84 candidates are on track to take one or more examinations. The total projected exams for the class of 2010 is 220. Twelve of the students are attempting the full diploma. About an additional 100 students in the junior class (2011) are registered in one or more IB classes. Of those juniors, approximately fifteen will attempt one or more exams during the May, 2010 exam period. Twenty-five of those juniors are on track for the full diploma.

Proyecto Saber

This one-of-a-kind bilingual/bicultural tutoring program was founded at Chief Sealth in 1970. Students in the Proyecto Saber class receive help in all academic areas as well as involvement in social and service activities. The goal of Proyecto is to provide a safe, productive, and welcoming environment where students can receive the help they need to be successful in school and in planning for their future. Proyecto Saber empowers students by promoting pride and self-esteem through culturally relevant projects, activities and cultural and historical presentations.

A main component of the Proyecto Saber program is the elective class that is offered five periods a day for .5 credits. The instructors are bilingual, speaking English and Spanish, and work with students one-on-one or in small groups to complete their homework and projects for their other classes. In order to receive an A in the class students are required to attend regularly, work on their homework daily, keep a record of their daily homework assignments and finished work, and complete special projects investigating their own backgrounds. Students may take the class as many times as needed and as their schedule can accommodate.

Career Programs

The Academy of Finance and the Academy of Travel and Tourism programs provide career pathways, internships, and employment. We also provide programs in Graphic Arts, Humanities, M.E.S.A., Events Marketing, Sports Marketing, Performing Arts, and Art/Ceramics/Photography, and Apprenticeship & Construction.

Basketball coach Colin Slingsby earned the West Seattle Chamber of Commerce's Westsider of the Year . In his acceptance speech, the coach said he was proud to be representing Chief Sealth, and the many improvements it’s made – not just in sports. He also won the Seattle Times Coach of the Year award this past season.
