Quick Answer
Your EE referencing should be accurate, consistent, and complete. Choose one approved citation style, use it the same way throughout the essay, cite every borrowed idea or quotation clearly, and make sure your bibliography matches the sources actually used in the essay.
What You'll Learn
- Consistency matters as much as the style you choose
- You must reference paraphrased ideas as well as direct quotations
- Weak referencing can undermine otherwise strong academic work
- A careful bibliography check should be part of your final EE edit
Why Referencing Matters in the EE
Referencing is not just a formal requirement. It shows academic honesty, helps the examiner see where your evidence comes from, and makes your argument more credible. In an Extended Essay, poor referencing can create doubts about your research habits and, in serious cases, raise academic integrity concerns. Strong referencing supports strong scholarship.
Pro Tip
If a fact, idea, interpretation, or phrase did not originate with you, cite it.
Choose One Citation Style and Stay Consistent
The IB does not require every subject to use the same referencing style, but it does expect consistency. Many students use MLA, APA, Chicago, or Harvard depending on the subject and supervisor guidance. The exact style matters less than applying it accurately throughout the essay.
- Check whether your supervisor or department recommends a style
- Use the same format for every in-text citation or footnote
- Keep bibliography entries consistent in order and punctuation
- Do not mix multiple styles unless your supervisor explicitly allows it
Watch Out
Switching between formats partway through the essay creates a rushed and unreliable impression.
Know What Needs to Be Cited
Students sometimes think citations are only needed for direct quotations. That is not enough. You also need to reference paraphrased ideas, data, statistics, specific interpretations, and any source material that shaped your argument in a traceable way.
- Direct quotations
- Paraphrased ideas and interpretations
- Statistics, datasets, or figures
- Specialist claims or arguments from critics or scholars
- Images, charts, and non-original visuals where relevant
Build a Bibliography That Matches the Essay
Your bibliography should not be an afterthought. It should accurately list the sources you actually used and follow the same style as the citations inside the essay. A clean bibliography gives the final paper a much stronger scholarly feel.
- 1Record full source details as you research, not at the end
- 2Check that every cited source appears in the bibliography
- 3Remove sources you listed but never actually used
- 4Format author names, titles, dates, and publication details consistently
- 5Review digital sources carefully, including access dates where needed
A Practical Referencing Workflow
The easiest way to avoid citation problems is to build good habits while drafting rather than trying to reconstruct sources at the end.
- 1Create a running source list from the start of the project
- 2Add citation details immediately when you take notes
- 3Mark direct quotations clearly in your notes
- 4Insert provisional citations in every draft
- 5Do a final pass only for consistency and formatting
Common EE Referencing Mistakes
These issues appear frequently in otherwise good essays.
- Missing citations for paraphrased ideas
- Inconsistent citation style across the essay
- Bibliography entries with incomplete source details
- Quotations copied into drafts without clear source tracking
- Heavy reliance on weak or non-academic online sources
