Each Diploma candidate must undertake original research and write an extended essay of about 4000 words with about 40 working hours during the two years as a result of research done by him in one of the academic subjects offered in the program. This project offers the student the opportunity to develop research and writing skills required at university. Each student will be assigned a teacher to supervise and guide his work all through the whole experience, which starts in November of the 11th grade. It is expected that the essay will be submitted towards the end of November of the 12th grade. An external examiner appointed by the IB examination board will assess the extended essay.
