Although not always required, an appendix can strengthen your Extended Essay by providing relevant supplementary material. However, it's important to use it appropriately and in alignment with IB guidelines. If you decide to include an appendix in your EE, this post is for you! Here, we'll break down what a good EE appendix looks like so that you can format yours accordingly, no matter the subject of your EE.
Extended Essay Appendix Guide
Purpose of the Appendix
The appendix is for supporting material that would otherwise interrupt the flow of your essay or would cause your essay to exceed the word limit of 4000 words.
Any evaluative or analytical content should not be placed in the appendix but rather in the main body of your essay.
The appendix should be a supplement to the main EE, not a place to dump extra information. The reader should be able to fully understand the EE based on the content in the main body, and should only refer to the appendix if they want extra details.
When writing the EE, assume the examiner will not read the appendix as it is beyond the 4000-word limit. It is up to each individual examiner if they want to see the appendix or not.
As such, the main EE should contain all the important information relevant to understanding the research question and its outcomes.
Referencing the Appendix
Any content in the appendix must be clearly referenced in the body of the essay. Use statements like: “See Appendix A for the full raw dataset” to guide the examiner to the appropriate section. Avoid vague references like “see the appendix” without indicating which section or why the examiner should look there.
The appendix should be easy to navigate with clear labels, headings, and consistent formatting (e.g. Appendix A: Raw Spectral Data, Appendix B: Calibration Curves, etc.).
The appendix is not a loophole to exceed the word count. Words in the appendix are not included in the official word count, but placing any analysis here may be penalized. Do not tell the examiner to refer to the analysis in the appendix, as the analysis must be presented in the main EE instead.
Types of Content You Can Include
Group 1 – Studies in Language and Literature
Extended literary excerpts referenced in the analysis (with citations).
Annotated copies of short poems or passages with close textual analysis.
Original translations of non-English texts, if used in the main EE.
Group 2 – Language Acquisition
Transcripts of interviews or surveys conducted in the target language.
Examples of cultural materials (e.g., advertisements, posters, news headlines).
Original versions of translated texts used in analysis.
Group 3 – Individuals and Societies
Raw survey data, tables, and charts.
Interview transcripts or extended quotations from primary sources.
Maps, timelines, or images relevant to analysis.
For Business – case study materials, financial data, SWOT/PEST analysis tables.
Group 4 – Sciences
Raw experimental data or calculation tables.
Sample logs, graphs, preliminary procedures, and extensive raw data tables.
Diagrams or schematics of experimental setups.
Group 5 – Mathematics
Detailed workings for complex derivations or proofs.
Large data sets or mathematical models.
Graphs, simulations, or raw calculator output.
Group 6 – The Arts
Sketches, storyboard frames, or production notes.
Photographs of artworks, set designs, or costume mock-ups.
Extended interview transcripts with artists or directors.
Scripts or scores referenced in your analysis.
Formatting and Presentation
Label each appendix clearly (e.g., Appendix A, Appendix B) and use consistent formatting. Keep fonts, margins, and spacing in the appendix uniform between the main EE and the appendix.
Arrange the appendices in the order in which they are referenced in the main EE. This helps the examiner follow your logic and find supporting material easily and in an organized manner.
Ensure your appendix looks professional and organized, just like the rest of your essay. Ensure all figures, tables, and graphs have a caption with a number and a brief description.
