The Extended Essay is an independent, self-directed piece of research, culminating in a 4,000-word paper. It is important, because it provides practical preparation for the kinds of undergraduate research required at tertiary level. From the choice of a suitable research question, to the final completion of the extended essay, students must produce their piece within the constraints of time, essay length and available resources. This component provides an opportunity to engage in an in-depth study of a topic of interest within a chosen subject.

Emphasis is placed on the research process, on the appropriate formulation of a research question, on personal engagement in the exploration of the topic, and on communication
of ideas and development of argument. It develops the capacity to analyse, synthesise and evaluate knowledge, with a personal choice of topic from within any subject area. Students are supported and encouraged throughout the Diploma Success Skills with advice and guidance from a supervisor.
