Internal Assessment by subject
An IB Internal Assessment (IA) is a subject-specific investigation marked against official criteria — typically 20–25% of your final grade. Each of the 25 Diploma Programme subjects has its own rubric, word limit, and criterion structure. iBacalao scores your draft criterion-by-criterion against the official descriptors for your subject.
iBacalao supports all 25 Diploma Programme subjects. Choose yours to see the full rubric and get instant, criterion-by-criterion feedback on your draft.
