The Upper School begins in Grade 9, and while courses build on those in the Middle School, they are designed to cater to new students who enter from other schools. Courses in Grades 9 - 10 serve as a preparation and background for International Baccalaureate courses in the later years.
Courses in Grades 11 and 12 prepare students for the International Baccalaureate Diploma and are offered at both Higher and Standard level to cater to students who may or may not choose to take the full diploma.
Brent International School Baguio is accredited through the Department of Education (DepEd, Philippines), the Western Association of Schools and Colleges (WASC, USA), and is a member of the Council of International Schools (CIS), thus providing us with the opportunity to offer a High School Diploma to those graduating students who do not wish to enroll in the International Baccalaureate. These students must meet the requirements for a Brent Diploma, recognized as a high school graduating diploma both in the Philippines and internationally. All students gain from the breadth of the IB program. Further details are available from the International Baccalaureate (I.B.) Coordinator / Director for Academic Affairs.
