What is the John Locke Essay Competition? It is a free global essay prize run by the John Locke Institute for students under 19, with ten subject categories, a 2,000 word limit, a submission deadline of May 31 in the 2026 cycle, scholarship prizes of $1,000 to $5,000 in each category, and a $10,000 Grand Prize, all judged by academics from universities including Oxford, Cambridge, Harvard, Princeton and Stanford.
This guide is written by YRI Fellowship, which runs its own free student competition, and we say that upfront. Facts about the John Locke Institute come from its official competition and prize winners pages as of November 2026, plus two named third-party sources, all linked in the Sources section.
What the John Locke Essay Competition is
The John Locke Institute, which runs summer schools and visiting scholars programs, calls this competition its Global Essay Prize. Each year it publishes a set of questions across ten subjects. Students choose one question, write an argumentative essay of up to 2,000 words, and submit it online. The Institute describes the prize as the world's most prestigious essay competition, and it receives tens of thousands of entries from students in more than 150 countries.
The questions are deliberately hard and open. They sit outside the school curriculum and reward a clear position defended with evidence. Recent questions asked students whether we should fear a cashless society, whether trial by jury is obsolete, and whether space exploration is a necessity or an indulgence.
The ten categories
Every year the competition runs in the same ten subjects. Each category has its own questions, usually three.
| Category | Example 2026 question theme |
|---|---|
| Economics | Personalised pricing, cashless societies |
| History | Whether history bends toward justice |
| International Relations | Foreign aid, cheap imports |
| Law | Determinism and criminal sentencing, jury trials |
| Philosophy | Doing the right thing for the wrong reasons |
| Politics | Self-determination, democracy in crisis |
| Psychology | Over-diagnosis of mental illness |
| Public Policy | Discount rates for environmental policy, vaccination mandates |
| Science and Technology | Free speech and science, space exploration |
| Theology | Neuroscience and religious experience |
Junior contestants may answer a question from any category. A student may submit more than one essay, one per category, and can win prizes in more than one category. Essays must answer a question from the current year's list. Last year's questions are not eligible.
Who is eligible
- Age: under 19 on the regular submission deadline. In 2026 that was May 31, so a student who turned 19 on June 1, 2026 or later could enter. There is no minimum age.
- Junior category: students under 15 on May 31 are judged in the Junior category. Everyone else is Senior. The category is set by age automatically.
- Country: open to students from any country.
- Solo work: team entries are not allowed.
- Referee: each contestant must give the email of an academic referee, ideally a school teacher, who is not a relative. The Institute emails referees to confirm the essay is the student's own work.
Word limit and format rules
| Rule | Official requirement |
|---|---|
| Word limit | 2,000 words maximum |
| Not counted | Diagrams, data tables, endnotes, bibliography, authorship declaration |
| Counted | In-text citations, if you use a style such as APA |
| Footnotes | Not allowed; endnotes and a clearly titled bibliography are allowed |
| File | PDF named FirstName-LastName-Category-QuestionNumber.pdf |
| Name | Must not appear inside the document |
| Language | English; American or British spelling, used consistently |
| Sources | Give sources for factual claims and credit authors you rely on |
The AI policy is specific. Students may use AI tools to develop their thinking and test arguments, but not as a substitute for writing. The FAQ goes further and says the safest course is not to use AI at all, since any use can only count against an essay. The Institute checks for plagiarism, contract cheating and AI use, and some candidates are invited to an online interview about their essay. Proofreaders may point out errors, but the student must make the corrections.
John Locke essay deadline
The 2026 cycle is complete. These were its dates, all at 23:59 GMT:

The 2027 questions and dates are not posted yet.

Registration is required before you can submit: a student who misses the registration deadline and the paid late registration window cannot enter.
John Locke essay prizes
All prizes are scholarships toward John Locke Institute programs, not cash.
| Prize | Value |
|---|---|
| First place, each category | US$5,000 scholarship |
| Second place, each category | US$2,000 scholarship |
| Third place, each category | US$1,000 scholarship |
| Grand Prize, best essay overall | Honorary Junior Fellowship and a US$10,000 scholarship |
Senior and Junior entries are judged separately, so each category awards six prizes. In 2026 the Institute named both a Senior and a Junior Grand Prize winner. A travel grant may be added in some cases. Shortlisted students can download an eCertificate, and prize winners who attend the London ceremony receive a signed certificate. Attending is optional and not free, and a student can win without travelling.
Entry fee
No. Entry is free. The only fees are $10 for late registration and, for late submission, 25 GBP for the seven-day extension or 75 GBP for the twenty-one-day extension. The late submission fee is charged once per contestant, not per essay.
How essays are judged
Judges are senior academics from universities including Oxford, Cambridge, Harvard, Princeton and Stanford, led by Chairman of Examiners Professor Terence Kealey. The published criteria are:
- knowledge and understanding of the material
- competent use of evidence
- quality of argumentation
- originality
- structure
- writing style
- persuasive force
The Institute adds that the best essays are likely to be the ones capable of changing somebody's mind, and that essays which ignore the strongest objections are unlikely to succeed. Students should answer the question as precisely and directly as possible. An ambiguous question can be interpreted, as long as the essay states the interpretation and then answers it directly. The grading system is proprietary, decisions are final, and the Institute does not give individual feedback.
One FAQ answer is worth reading twice: students do not need to agree with the judges. The Institute says a large share of prizewinners have argued positions most of its faculty disagree with.
How to win the John Locke Essay Competition
The Institute publishes selected winning essays on its past essays page, and the prize winners page lists recent winners from dozens of countries. Read at least two winners in your category before you write. Combined with the official criteria and the Pioneer Academics guide in the Sources, the pattern is consistent:
A good preparation habit is reading around the question the way a researcher would. Our guide to writing a literature review shows how to summarize and compare sources quickly, and how to choose a research topic helps a student pick the question they can argue best.
The odds, frankly
The competition is large. St. Olave's Grammar School reported that the 2026 competition attracted 100,227 entrants from 183 countries, with the shortlist made up of the top 17.5% of eligible submissions. The Institute itself does not publish an official shortlist rate. Against that, there are 60 category prizes, ten categories with three places each in Senior and Junior, plus the Grand Prizes. A shortlist place is a respectable result. A prize is rare.
That is a reason to enter for the right reasons. A well-argued 2,000 word essay is excellent practice in research and writing, and it costs nothing. As a stand-alone line on a college application, though, a shortlist from a competition with tens of thousands of entries carries less weight than original work that the student owns over months.
A free alternative with a Fellowship prize
YRI runs its own free competition for students who want to go a step further than an essay. The YRI Global Research Proposal Competition asks high school students anywhere in the world to submit a 1,000 word research proposal on any subject. Entry is free, the deadline is January 10, 2027, and first place wins a full YRI Fellowship scholarship with a PhD mentor.
| John Locke Essay Competition | YRI Global Research Proposal Competition | |
|---|---|---|
| Entry fee | Free | Free |
| Length | Up to 2,000 words | 1,000 word proposal |
| Subjects | Ten set categories, set questions | Any subject, student's own question |
| Next deadline | 2027 dates not posted; May 31 in 2026 | January 10, 2027 |
| Top prize | US$10,000 scholarship to Institute programs | Full YRI Fellowship scholarship and a PhD mentor |
A proposal is the first step of a research paper: a question, why it matters, what is already known and how you would test it. Students who write a strong John Locke essay already have most of the skills, and the January deadline comes well before the next Locke cycle.
From an essay to a published paper
An essay argues a position. A research paper produces new evidence. Admissions readers see thousands of competition entries, and far fewer first-author papers in peer-reviewed venues.
The YRI Fellowship is 10 weeks of 1:1 work with a PhD mentor, ending in a first-author paper submitted to a peer-reviewed IEEE, Springer or Elsevier venue. Mentors cover the humanities and social sciences as well as STEM, so a student drawn to the Locke questions in economics, psychology, politics or law can turn that interest into original research. ISEF and JSHS preparation is included, the mentor writes a letter of recommendation, and mentorship continues at no extra cost until the paper is published. 87% of Fellows publish, and Fellows have been admitted to Brown, Johns Hopkins, Stanford, Caltech and Harvard. The program is $2,997, with a 3-month payment plan.
