IA Overview
The internal assessment requirements are the same for biology, chemistry and physics. The internal
assessment, worth 20% of the final assessment, consists of one scientific investigation. The individual
investigation should cover a topic that is commensurate with the level of the course of study.
Student work is internally assessed by the teacher and externally moderated by the IB. The performance in
internal assessment at both SL and HL is marked against common assessment criteria, with a total mark out
of 24.
