What referencing style does the IB (International Baccalaureate) require?

Due to the number of languages in which members of the IB community complete their work, and the diversity in subject areas, the IB does not endorse any particular style guide. The choice is left to the discretion of the authors/creators, or their academic advisers.

According to the International Baccalaureate Organization:

“Due to the wide range of subjects, multiple response languages and the diversity of referencing styles, the IB does not prescribe or insist on a particular style”


“The IB’s requirements are for honesty in indicating when and which ideas and words are not the writer’s own, and consistency in referencing the source of those ideas and words.”

In case you are not sure which referencing style to use for your academic work, ask your IB coordinator at school. Otherwise, feel free to pick one of the most commonly used styles:

  • MLA (Modern Language Association) 
  • APA (American Psychological Association) 
  • Harvard • Chicago/Turabian 
  • CSE (Council of Science Editors) 
  • ISO 690 (International Organization for Standardization)
