Do Colleges Care About High School Research? What Admissions Offices Actually Say

If you're applying to competitive colleges, you've probably heard that doing research in high school can help you stand out. But how much does it actually matter? Do colleges look for research, or is it just another extracurricular?

To find out, we went to the source: what the admissions offices at Harvard, Yale, MIT, Penn and Caltech publish about research, and what education research says about the skills it builds. For the wider case for doing research at all, see our high school research playbook and why research programmes can transform your future. This post is about how colleges themselves treat it.

Do Colleges Value High School Research?

Yes, and the clearest evidence is in how they build their applications. Several highly selective colleges have set up a dedicated route for research - a supplement, a form or an upload, often with a letter from your research mentor - alongside the routes they offer for arts portfolios.

• Harvard says some applicants "demonstrate extraordinary promise in academic or research endeavors" (counselor newsletter, fall 2024), and lets applicants upload scholarly articles or research of which they are the primary author. Submissions should list collaborators and, where relevant, the research mentor, with a short description of the applicant's own contribution.
• Yale says applicants "may supplement their application with an arts portfolio or academic research." Science and engineering research goes through a STEM Research Supplement form that takes a paper, abstract or poster and lets you invite your research mentor to send a letter; other academic work is uploaded separately.
• MIT offers a Research Supplement for students who have worked on "a significant research project outside of high school classes": a short questionnaire, an abstract or poster, and a letter from your research mentor.
• Caltech asks research applicants for a full paper where possible, a research description form and an additional recommendation from the research site. If research opportunities were available to you, it says, "we want to learn more about your experience."

Applicants who have done research choose to send it this way, and a college does not build a research form with a mentor letter for something it does not read.

How Many Admitted Students Have Done Research?

Two colleges have published figures. Caltech reports that 42% of its admitted students had participated in research before arriving. Penn's dean of admissions wrote of the Class of 2026, in 2022: "Nearly one-third of the admitted students engaged in academic research during their time in high school, many earning national and international accolades for research that is already pushing the boundaries of academic discovery."

These are single-year figures, but at two of the most selective colleges in the US, somewhere between a third and two-fifths of admitted students arrived with research behind them.

Why Does Research Read Well on an Application?

Because it shows the qualities admissions offices say they look for. Caltech looks for "Scientific Drive", which it defines as "Relentless and purposeful pursuit of questions, problems, and discovery", and lists signs of it that read like a description of a good research project: "Self-directed exploration beyond assigned work", "Original thinking or substantive contribution" and "Returning to scientific questions or projects over time". MIT calls itself "an active, hands-on place" where "Students apply theoretical knowledge to real-world problems", and puts research projects first among the opportunities it expects students to take the initiative to pursue.

Education research points the same way. A 2017 National Academies report on undergraduate research experiences in STEM describes them as engaging students "in research practices including the ability to argue from evidence" and requiring them to communicate their results, and concludes that "the published peer-reviewed literature to date suggests that participation in a URE is beneficial for students." The report studied college undergraduates rather than high school students, but the skills it describes are the ones admissions offices name.

The American Association of Colleges and Universities likewise counts undergraduate research among its high-impact practices - "teaching and learning practices that research has shown to provide significant educational benefits for students" - with the goal of involving students "with actively contested questions, empirical observation, cutting-edge technologies, and the sense of excitement that comes from working to answer important questions."

What Makes Research Count?

The same admissions pages say what they want to see. Three things come up again and again:

• Your own contribution. Harvard asks for a short description of your part in the work, Yale's form asks for "your specific contributions if the work was done in collaboration with others", and Caltech's recommender "must speak to your specific contributions to the submitted research." Alongside the name of the programme or project, say whether you designed the survey, analysed the data, built the method or interpreted the findings.
• A mentor who can vouch for you. MIT, Yale and Caltech all build a research mentor's letter into their research submissions, and the National Academies report concluded that "The quality of mentoring can make a substantial difference in a student's experiences with research."
• A finished output. Caltech says a full research paper "is strongly preferred", Yale says "Full research papers are generally the most helpful", and MIT takes an abstract or poster. A paper, poster or report gives an admissions reader something concrete to look at.

A mentored programme is built around all three. In Hinksey Labs' Research Scholars and Research Fundamentals, each student writes their own research paper on a real organisation's challenge, each small team works with a dedicated Ivy League or Oxbridge PhD or MBA mentor, and outstanding students may receive a recommendation letter at their mentor's discretion.

Research also extends well beyond science laboratories. A student interested in economics might investigate consumer behaviour, while someone interested in AI could evaluate how algorithms perform across different populations. One practical point: Yale's research form is for science and engineering, so business or economics research goes in as other academic work. Our research playbook covers how to get started across STEM, business, economics, AI and the social sciences, and Research Without the White Coat makes the case for business research specifically.

The important question isn't how impressive a project sounds. It's whether you can explain the question you investigated, the work you did and what you learned.

Does Research Need to Be Published to Count?

No. Colleges take unpublished work seriously. MIT asks for an abstract or poster if you have one, and a citation "if the work being submitted has been published." Caltech says submitted papers "can be published, submitted, or in preparation."

Publishing gives the work a tangible outcome and an outside reader, which is worth having. What admissions offices read for is still the quality of the work and your part in it. If you're considering it, our guide to getting research published in high school explains how to prepare a paper, and where high school students can publish research compares the journals.

What About Students at International Schools?

Students at international schools may have different access to research, particularly in curricula such as the International Baccalaureate (IB), A-levels or a national system. US admissions offices say explicitly that they take this into account.

Penn evaluates international applications "with the context of your local opportunities and national education systems in mind," and recognises that access to extracurricular opportunities varies from country to country. Yale considers each applicant "within their own context" and looks at how you have used the resources and opportunities at your school. Penn also reads each application against the school profile, which sets out the curriculum and the extracurricular opportunities your school actually offered.

For international-school students, research might be an IB Extended Essay, an Extended Project Qualification (EPQ) at a British school, a school-based investigation or an independent project on a local issue. These are not all treated the same way. MIT's Research Supplement, for example, is for projects done outside high school classes, so required coursework such as the Extended Essay may not fit it unless you took the work further on your own - what an Extended Essay can become after it is marked is its own question.

The takeaway for international applicants: make meaningful use of the opportunities available to you rather than trying to replicate another student's profile. Online programmes widen what is available wherever you study: all Hinksey Labs programmes are delivered fully online.

How Should You Include Research in Your Application?

Where a college has a research supplement, use it and follow its instructions exactly. Where it doesn't, the rest of the application carries the work: Stanford does not add research papers to the application file, and Penn recommends using the activities and additional information sections to convey this kind of information. Either way, your activities entry is the place for your role, methods and outcomes. Compare:

Vague: Independent Researcher - Studied social media and consumer behaviour.

Specific: Designed a survey investigating social media's influence on purchasing decisions; analysed responses and presented findings.

The second gives a far clearer picture of the student's contribution - the action, contribution and result that our guide to extracurriculars asks for. You can also write about research in an essay if it genuinely shaped your interests.

The Bottom Line

Colleges care about high school research. The most selective of them build forms, uploads and mentor-letter routes for it, publish how many of their admitted students have done it, and describe what they look for - initiative, sustained curiosity, original contribution - in terms a good research project demonstrates.

Like every part of a holistic application, research is read alongside your grades, essays and recommendations. What makes research count is a real question, your own contribution, a finished output and a mentor who can vouch for how you worked. Good research starts with a question worth exploring; investigate it properly and you will have something genuine to say about the experience.
