International Baccalaureate® Diploma Programme

IB World School Overview


  • International Baccalaureate Diploma Programme (IBDP)The IB curriculum requires that students study a subject in depth (courses focused on mastery of a subject) and not limited to focus on breadth (survey courses). Additionally, the curriculum allows students to study disciplines from an American perspective as well as an international perspective.


  • The assessment (papers) in IB classes is based on a mixture of knowledge, application, analysis, synthesis, and evaluation. Most of the assessment requires that students be capable of applying, analyzing, synthesizing, and evaluating knowledge, not just regurgitating knowledge. There is very little multiple­ choice assessment in IB exams. The writing and thinking skills that students need to possess when they graduate from high school are the foundation of an IB Diploma.


  • Colleges and universities recognize the IB curriculum for its emphasis on developing critical thinking skills and its ability to prepare students for success in college and beyond. It is expected that the IB will help increase college placement rates and the placement of graduates in highly selective colleges.


  • WaPrep students can expect their IB credential will translate into more advance placement opportunities when they enter college or university. Additionally, WaPrep students will be eligible for scholarships that some higher education institutions reserve for IB Diploma graduates.


  • As WaPrep goes forward with the implementation of the IB, students will still have the ability to take the AP exams and will be well prepared for those exams.

I am pleased to announce that Washington Preparatory School has been authorized by the International Baccalaureate Organization to offer the International Baccalaureate Diploma Programme (IBDP) starting in the Fall of 2020. It will be the only private independent school in King and Snohomish Counties to offer the Diploma Programme.
