An IB Internal Assessment (IA) is a significant piece of coursework completed during the course and assessed internally by your school teacher, with marks moderated by the IB. It contributes 20-30% of your final subject grade.
-
Purpose: To assess skills that exams cannot easily test, such as laboratory work, research, oral performance, or artistic creation.
-
Format: Varies by subject—a lab report in Sciences, a mathematical exploration in Math, a written task in Languages, a historical investigation.
-
Process: Teachers grade using IB criteria, then a sample of IAs from the school is sent to IB moderators to ensure grading standards are consistent globally.
Performing well on IAs is crucial, as they provide a grade cushion before you even sit for final exams.
