" All work submitted to the IB for moderation or assessment must be authenticated by a teacher, and must not include any known instances of suspected or confirmed academic misconduct. Each student must confirm that the work is his or her authentic work. [...] Authenticity may be checked by discussion with the student on the content of the work, and scrutiny of one or more of the following.
- the student's initial proposal
- the usual quality of the student's work
The same material cannot be submitted to meet the requirements of both the internal assessment and the extended essay. The works used in the internal assessment must be different from those used in other assessment components."
