Diploma Programme assessment
Examiners
The IB uses about 5,000 examiners worldwide. They ensure that student work is assessed fairly and consistently.
- Many IB examiners are experienced Diploma Programme teachers.
- Examiners receive detailed instructions on how to mark the work sent to them.
- Examiners send a sample of their marking to a more senior examiner for checking.
Each subject has a group of senior examiners who prepare examination questions, set the standard for marking and determine the marks needed for the award of each subject grade.
There is a chief examiner for each subject, usually an academic from higher education, with international authority in their field.
