IB TEACHERS / COORDINATORS 2025-2026
It's important to know, AST's IB Diploma curriculum and all of its IB components in the IB program address every expectation The IB Organization requires!
Each year, every IB teacher's curriculum is checked to ensure it is aligned to the desired learning outcomes which IB is seeking. This is done by administrators who directly supervise specific teachers.
Teacher effectiveness is evaluated throughout the school year; yearly reviews by the high school administration team are completed before IB staffing is finalized for the next school year.
All IB teachers must complete IB training (a month long course) before they teach any IB course, and additional training is required when any changes are made to a course’s curriculum.
The IB Organization does a thorough review of our IB Diploma Program every 5 years. It is a 15 month process, and everything the IB Organization expects to be present in the IB Diploma program is thoroughly reviewed.
