Pen and paper exams take place in May, during the school day, at Mt. Rainier High School.  Most subject areas have 2 "papers" and are tested in 45 min to 2 hour blocks over two days.  Exam dates and times may not be adjusted for extra curricular competitions or family vacations.

Exams are FREE to all students and carry the possibility of college credit.


Extended Essay (EE)

IB requires Diploma students to undertake an independent research project in a subject of their choosing and write 3500-4000 word essay on their findings.  This highly individualized project allows the Diploma student to demonstrate their research, thinking, and communication skills through the investigation of a topic of individual interest.  Students work with a faculty supervisor for 3-6 hours over the course of the project.  Diploma students begin this project in the junior year and have roughly one (1) year in which to complete their work.



Creativity Activity Service (CAS)

IB requires Diploma students to participate in self-directed of experiences that begin in 11th grade and continues uninterrupted for 18 months.  Students should design a program that reflects a balance between the three CAS components and allows the student to meet the CAS guidelines (inclusive of the Student Learning Outcomes, CAS Stages and Group Project).
