Regeneron STS Brief

Counselor intelligence brief

Regeneron Science Talent Search

A practical planning guide for turning serious high-school research into a Regeneron STS submission: eligibility, strategy, timeline, and the kind of project architecture that can credibly compete.

Snapshot date May 14, 2026. Society for Science says the 2027 application opens June 1, 2026 and closes in early November 2026.

1. What Regeneron STS is

Regeneron STS is the United States' oldest and most prestigious science and math competition for high-school seniors. It is run by Society for Science and sponsored by Regeneron, with 300 scholars, 40 finalists, and more than $1.8 million in awards each cycle.

The core product is not a poster. It is a full application built around an original, independent research report, essays, recommendations, transcripts, and evidence that the student has unusual scientific promise. Treat it like a research thesis plus a leadership file.

Applicants

2,600+

2026 was the largest applicant pool since 1967.

Scholars

300

Each scholar and school received a $2,000 award in 2026.

Finalists

40

Finalists compete in March for top national awards.

2. Eligibility and cycle timing

The first screen is procedural. If the student or project fails here, stronger science will not rescue the application.

A strong STS candidate usually has

  • Original research conducted during high school.
  • A clear individual contribution that can be defended without a teammate.
  • A mentor who advises without becoming a hidden co-author.
  • Enough time to write, revise, document approvals, and collect recommendations.

The common disqualifiers

  • Team research presented as individual work.
  • Missing pre-approval or documentation for regulated research areas.
  • Student is not in the eligible senior-year category.
  • Late application, late recommendation, or unresolved application issue after the support window closes.

3. The project that can compete

Regeneron rewards more than technical polish. The entry needs a scientific claim, a believable method, and visible student judgment.

What judges are scoring

  • Originality

    A real question, not a packaged demonstration or polished class project.

  • Scientific rigor

    A research report that can survive Ph.D.-level review, including limitations.

  • Independence

    The idea, execution, analysis, and writing must be the student's own work.

  • Leadership promise

    Essays and recommendations need to show the student behind the science.

How to shape the research

  • Anchor the question

    Start with a mechanism or phenomenon the student found, then make the model serve that discovery.

  • Beat a baseline

    STS readers need to know what changed because of the student's work. A credible benchmark is cleaner than a dramatic adjective.

  • Show the student's judgment

    A strong entry explains why tempting alternatives were rejected, not just what finally worked.

  • Keep the paper defensible

    Every figure should connect to the central claim, with no cosmetic charts padding the report.

Client strategy pattern

Discovery first, model second

For an Avery-style climate project, the clean STS arc is: build or discover a novel regime, show why existing models miss it, then design a predictive model that uses the discovery and beats a published baseline in the regime where the old approach fails.

1. Novel artifact

Catalogue, dataset, proof, sensor, assay, or pipeline.

2. Mechanism

What the artifact reveals that was not visible before.

3. Benchmark

A fair baseline that makes improvement measurable.

4. Interpretation

Why the result happened and when it does not generalize.

4. Roadmap to submission

Work backward from early November. The submission month is for writing and quality control, not discovering whether the experiment works.

  1. May to June

    Lock mentor boundaries, confirm individual ownership, audit prior research, and define the claim that would be worth a 20-page report.

  2. June to July

    Rebuild data and baselines, create reproducible notebooks, and write a short methods memo before adding complexity.

  3. July to August

    Run the main experiment, ablations, and negative controls. Freeze a versioned analysis pipeline.

  4. September

    Turn results into figures, compare against credible baselines, and collect enough failure cases to make the discussion honest.

  5. October

    Draft the research report, essays, and recommendation packet. Submit support tickets before the 24-hour support guarantee window.

  6. Early November

    Submit the full application and recommendations before the 8pm ET deadline once the 2027 exact date is posted.

5. Readiness check

Use this as the first advising screen before committing a student to the STS sprint.

  • Eligible senior

    Last year of secondary school in the U.S. or territories, or a U.S. citizen abroad.

  • Individual research

    No team project split apart for STS, even if roles were different.

  • Original report

    Maximum 20-page scientific paper, written by the student, with appropriate citations and documentation.

  • Documentation clean

    Human subjects, animals, tissues, cell lines, pathogens, and hazardous agents need rules review before submission.

  • Recommendation plan

    Teachers and mentors need deadlines, project context, and enough lead time to write specifically.

If time is tight

Cut scope before cutting rigor. A smaller claim with clean evidence beats a sprawling project with soft controls.

If the mentor is strong

Define advisory boundaries in writing. STS wants independence, not invisible lab authorship.

If the result is negative

A negative result can still work if the question mattered, the test was fair, and the explanation is scientifically useful.

6. Official resources

Keep these links close. The 2027 official rules are expected in June 2026, so the site should be refreshed after Society for Science posts the new packet.
