You can feel the moment it happens: you’re deep in your IA draft, the argument finally makes sense, and then you paste in one perfect statistic or definition.
And a quiet thought shows up: Where did I get that from?
In an IB IA (and in the EE), that question isn’t a small detail. It’s the difference between work that looks like real scholarship and work that looks like it borrowed confidence without permission. Proper citation doesn’t just keep you safe from academic misconduct. It makes your writing believable, traceable, and calm to read.
Below are 10 best practices for citing sources properly in your IB EE and IA, written for students who want high marks without last-minute panic.
A quick IA citation checklist (save this)
Before you polish formatting, make sure your IA can pass these quick checks:
-
Every borrowed idea, fact, definition, dataset, and image has a citation.
-
You’ve chosen one citation style (APA/MLA/Chicago) and used it consistently.
-
In-text citations match the final reference list exactly.
-
Visuals have a source in the caption and in the reference list.
-
Online sources include enough detail to find them again.
If you want extra support on sourcing expectations, skim How Many Sources Should an IA Have? and keep it open while you edit.
Best practices for citing sources properly in IB EE and IA
Cite anything that isn’t yours (ideas, words, data, visuals)
In an IA, plagiarism rarely looks like copying a whole paragraph. More often it looks like a “small” sentence that states a fact as if it’s common knowledge when it’s actually from a textbook, article, database, or website.
Cite when you:
-
Quote directly.
-
Paraphrase an author’s explanation.
-
Use numerical data you didn’t generate.
-
Recreate a figure, table, model, or graph from somewhere else.
A useful rule: if the reader could reasonably ask “How do you know that?” your IA probably needs a citation.
Pick one citation style and commit to it
The IB doesn’t force one universal style across every subject. But it does expect a recognized academic style applied consistently.
Consistency is what examiners feel immediately. Mixed styles signal rushed research and sloppy control. Choose a style your subject commonly uses, then follow it everywhere: in-text citations, footnotes (if relevant), and the reference list.
Make in-text citations specific enough to trace
Your IA should let someone find the exact claim in the exact source. That means your in-text citation needs the right level of detail.
-
For print sources, include author + year (or author + page, depending on style) and page numbers for quotes.
-
For online sources, cite author or organization, year/date, and use a full reference entry with the URL.
Specific citations don’t just prevent problems. They strengthen your analysis because they show you can locate your evidence precisely.
Use quotations sparingly and format long quotes correctly
An IA and EE are not quote collections. Examiners award marks for your thinking. Quote only when wording is uniquely important, then explain why it matters.
If a quotation is long (often 3--4 lines or more, depending on style), format it as a block quote according to your chosen style and still cite it correctly. The key is clarity: the reader should see where your voice ends and the source begins.
Build a clean, alphabetized reference list
Your reference list is not a decoration. It’s the map of your research.
Best practice is one alphabetized list, not separated by “books/websites/videos.” Include full details: author, title, date, publisher/journal, and stable access information for online sources.
If you’re unsure how strict the IB is about integrity and attribution, read What Are IB’s Expectations for Academic Honesty in the Extended Essay (EE)?. The principles apply to your IA too.
Treat visuals like evidence (and cite them twice)
In many IAs, visuals carry a lot of weight: diagrams, screenshots, photos, graphs, maps. But they also create easy citation mistakes.
Best practice:
-
Put a source in the caption under the figure/table.
-
Add the full reference in your reference list.
And if you adapted a visual, say so. “Adapted from…” is honest and examiner-friendly.

Record full details for online sources immediately
Online sources disappear, move, or update. Your IA should protect itself from that.
When you find a useful page, capture:
-
Author/organization
-
Date published or last updated (if available)
-
Page title
-
Full URL (avoid shortened links)
-
Access date (often required)
If you only paste a link into your notes, you’re gambling with future-you’s sanity.
Track sources from day one (don’t “add them later”)
Most citation disasters come from one plan: “I’ll do references at the end.”
Instead, run a simple workflow:
-
Keep a running source log.
-
Paste quotation + page number immediately.
-
Write a one-line note on how you might use it.
RevisionDojo’s IA Guides help you map research into a structure that naturally includes sourcing, so citations don’t feel like an extra job at the end.
Understand word count pressure without deleting citations
Students sometimes cut citations to reduce words. That’s a bad trade.
In many subjects, your bibliography is typically not counted in the IA word count, while in-text citations usually are because they sit inside your paragraphs. The solution is not to delete citations. The solution is to tighten phrasing.
For a practical breakdown, see Do References Count in the IA Word Count?.
Do a final “cross-check audit” before submission
The most effective last step is boring and powerful:
-
Every in-text citation appears in the reference list.
-
Every reference list entry is actually used in the IA.
-
Author names and dates match exactly.
-
Captions have sources where needed.

Closing: Make your IA feel like real scholarship
A strong IA isn’t just well-written. It’s traceable. It shows where evidence came from, how you interpreted it, and why your conclusion deserves trust. When your citations are consistent, your argument feels calmer, and you walk into exams knowing your coursework is solid.
