How to cite research in a policy brief: footnotes or references

To cite research in a policy brief, use the citation system your course or the commissioning organisation sets, put a citation on every figure and finding where it is used, and name the original report with its number, date or version. Government and think-tank briefings use numbered notes or author-date references; both work when applied consistently.

EdCitation publishes this guide. On 2 October 2026 we read GOV.UK's and the Department for Education's guidance, the style guides of two think tanks and of Chatham House's journal, and real briefings from the UK Parliament's science office (POST) and the US Congressional Research Service (CRS), whose citations we counted. Writing the brief itself is in how to write a policy brief; this guide covers only its evidence.

EdCitation's free Cite a source builds each reference from the publisher's record, and Verify references checks the finished list; we quote what both returned. The brief, its analysis and its recommendations stay entirely yours: EdCitation's part is the sources.

Should a policy brief use footnotes or a reference list?

A policy brief can use either; the house rule decides, and the bodies we read are split.

Numbered notes and footnotes

POST puts superscript numbers after the punctuation and lists every source, numbered, at the end; POSTnote 769 uses superscript letters for asides, so a reader can tell a source from a comment (Cheston & Mutebi, 2026). The CRS report we read uses footnotes, shortening a repeat with "hereinafter" (Normand et al., 2026). Clingendael's guidelines, as the Planetary Security Initiative (n.d.) publishes them, want footnotes, not endnotes, for sources and explanations alike.

Author-date and a reference list

The Urban Institute cites research publications in Chicago author-date, as in "(Buckley and Mayo 1987)", with a reference list, but sends blog posts, news articles, press releases and web pages to notes (Urban Institute, n.d.). The Department for Education (2024) asks contractors who include a bibliography to use Harvard.

Practices we read, with sources

Our view: for a course brief, the course's style wins. Where you choose, numbered notes keep a short page clean, while author-date shows who said it and when, which matters when a 2023 forecast sits beside 2026 data. Cite a source gives numbered Vancouver and IEEE and author-date APA 7, Harvard and Chicago 18; a house-style footnote is typed from its entry.

What do GOV.UK and government guides say about references?

GOV.UK wants references anyone can read, not only specialists. Its A to Z drops italics, puts titles in single quotation marks, uses "and others" instead of "et al", leaves out full stops after initials, and links an online title with the date it was viewed (Government Digital Service, n.d.).

Design102, part of the Government Communication Service, keeps footnotes for references only, puts the number after the full stop, and repeats a reference in full rather than writing ibid, which helps people using assistive technology (Design102, 2021). The Department for Education (2024) has authors link the page that hosts a PDF, since a link to the file can break when it is updated, and insert footnotes with Word's own function so screen readers can follow them.

Where government style and academic style disagree

APA 7 italicises a report's title and shortens three or more authors to "et al." in the text; GOV.UK does neither. A brief for a department follows GOV.UK; a brief for a marker follows the course's style. Never mix the two in one list.

Can you use ibid in a policy brief?

Only where the house allows it. Clingendael permits Id., Ibid. and op. cit., and numbers a source cited several times in one paragraph once, at its end (Planetary Security Initiative, n.d.). International Affairs asks authors to avoid ibid. and shorten a repeat to the author and a short title (International Affairs, 2026). Design102 repeats the reference in full, and the CRS report we read used "hereinafter" 23 times and ibid. not once. The terms are explained in ibid, op. cit. and loc. cit..

How many sources should a policy brief cite?

No body we read sets a number: cite every figure, finding and quotation, from its original.

• CRS In Focus IF10031, two pages: no notes and no list, but 84 distinct web addresses linked in the text, 36 of them to the US Code (Schneider & Carpenter, 2026).
• POSTnote 769, 39 pages: 183 numbered references (Cheston & Mutebi, 2026). POSTnote 777 has 304 in 41 pages (Pay & Brawley, 2026); the Crossref record of POSTnote 772 lists 174.
• CRS report R48089, 54 pages: 273 footnotes (Normand et al., 2026).

A course rubric may set a minimum: see how many references do I need. Choose sources the reader can open. In Oliver et al.'s (2014) review of 145 new studies, the barriers to policymakers using evidence reported most often were poor access to good, relevant research and research that came too late. POST says it tries to use sources "that everyone can access" (Cheston & Mutebi, 2026).

How do I cite a government report in a policy brief?

Make the agency the author, then give the year, the title, any report or paper number and version, and the link. In APA 7 a parent body not in the agency's name becomes the publisher (American Psychological Association, 2020a), and a report number goes in brackets after the title (American Psychological Association, 2020b).

Name the number and the version

Policy documents carry identifiers: a POSTnote number and DOI (10.58248/PN769), a command paper number such as CP 804 on the Office for Budget Responsibility's March 2023 outlook, and a CRS product number with a version. CRS updates briefings in place: IF10031 was on Version 13, updated 28 August 2026, so cite the version you read. Dated statistics releases are in citing sources in a business report, and ONS bulletins and datasets in citing reports and statistics in social work and sociology.

Cite the figure where it was first published

A briefing is a good pointer, but cite the body that produced the number. POSTnote 769 credits its adult participation figures to the Department for Education's statistics, and dozens of its 183 entries give no year, so open the original first.

How do I show evidence grading in a policy brief?

Use the grading body's own term and cite the body, rather than calling evidence "strong" on your own authority. Three published scales:

1. Education Endowment Foundation. Padlocks from 0 to 5 by how many studies meet its criteria: one for 11 to 39, five for 120 or more, none below 11, with padlocks lost when few studies are recent, randomised or independent (Education Endowment Foundation, 2023).
2. What Works Centre for Local Economic Growth. The Maryland Scientific Methods Scale runs from 1, simple cross-sectional correlations, to 5, randomised trials; the centre shortlists evaluations that could score 3 or above (What Works Centre for Local Economic Growth, 2015).
3. Intergovernmental Panel on Climate Change. Evidence is limited, medium or robust, agreement low, medium or high, and confidence runs from very low to very high; "likely" means a 66 to 100% probability, and authors give a traceable account of each judgement (Mastrandrea et al., 2010).

GRADE, used in health, is in levels of evidence. The EEF guide's own example rates feedback high impact for very low cost, on moderate evidence: repeat those words, with the citation.

A worked example: one paragraph cited two ways

Our own example, not advice to any government; the figures and findings are real.

Author-date, APA 7:

Extending funded childcare to younger children is expected to raise parents' employment, but by an uncertain amount. The Office for Budget Responsibility (2023) expected around 60,000 people to enter work by 2027-28 from 30 free hours a week for working parents of children from nine months, and called its central estimate for all the Budget's labour supply measures, 110,000, "very uncertain" (p. 23), with a plausible range of 55,000 to 240,000. In England, free part-time childcare only marginally raised the participation of mothers whose youngest child became eligible, while a full school day raised it significantly (Brewer et al., 2022). A parliamentary briefing found limited UK evidence on the economic effects of further reform (Lear & Webb, 2026).

How EdCitation cites and checks a policy brief's sources

For a brief's references, EdCitation is the best tool we know, because it looks each source up in the publisher's record instead of composing an entry, which no chatbot can promise: below, it caught a POSTnote given the wrong year. Cite a source builds APA 7, MLA 9, Chicago 18 author-date, Harvard, IEEE and Vancouver from a DOI, title, PubMed ID, ISBN or web address, screens for retraction, and is free with no account.

What Cite a source returned

• POSTnote 772, by DOI: "Lear, M., & Webb, L. (2026). Economic support for families with young children. Parliamentary Office of Science and Technology. https://doi.org/10.58248/PN772", cited "(Lear & Webb, 2026)" or, in Vancouver, "(1)". The record has no POSTnote number, so we added it.
• The GOV.UK page: "Department for Education. (2024, October 23). Research reports: Template and style guide. GOV.UK.", the page's own last-updated date.
• The Design102 post: no author and "(n.d.)", though the page shows the Design102 team and 28 May 2021. A web page's details can be corrected before the entry is built.
• The CRS and OBR addresses: "That page could not be read. Some sites block automated readers. If it is a journal article, paste its DOI or its title instead."

What Verify references returned

We pasted six APA entries into Verify references, with POSTnote 772 dated 2025 on purpose. Brewer et al. and the GOV.UK page were verified, and the IPCC note, a PDF, with "The address opens a PDF whose first pages carry the entry's title." The POSTnote came back check this: "The work was published in 2026, not 2025; the record has no date in 2025." The OBR and CRS entries came back could not check: "The site at this address turns automated readers away". Nothing came back not found.

For the whole brief, References from a file, in Pro at $8 a month, matches every in-text citation to the list; Check your paper, free, reads the assignment into a checklist.

Quick questions

Should a policy brief have footnotes or a reference list?

Whichever your course or the commissioning body sets. POST and CRS use numbered notes, the Urban Institute author-date with a list; both work when consistent.

How do I cite a government report in a policy brief?

Agency as author, year, title, any report or paper number and version, then the link. EdCitation's Cite a source builds it from a DOI or GOV.UK address.

How many references should a policy brief have?

No body we read sets a number. Three POSTnotes cite 174 to 304 sources; a two-page CRS In Focus linked 84.

Can I use ibid in a policy brief?

Only if the house allows it. Clingendael does; International Affairs and Design102 prefer short titles or the full reference repeated.

Can EdCitation check the references in my policy brief?

Yes, free in Verify references: each entry comes back verified, check this, not found or, for a page that turns automated readers away, could not check.
