TL;DR

• Regeneron ISEF is the world's largest pre-college science competition.

• You must qualify through an affiliated fair before attending ISEF.

• Projects are judged on scientific method, not just results.

• Strong documentation and a research paper improve your score significantly.

• Publishing your research before or after ISEF strengthens your academic record.

You have a research idea. Maybe you have already run experiments. Now you are wondering whether Regeneron ISEF is within reach, and what it actually takes to get there. That confusion is normal. The competition has a reputation that can make it feel distant or impossibly selective, but the path is more structured than it appears.

Regeneron ISEF, which stands for International Science and Engineering Fair, is run by Society for Science and has been held annually since 1950. It brings together roughly 1,800 students from more than 40 countries each year, all of whom qualified through regional or national affiliated fairs. The competition spans 22 categories, from behavioral and social sciences to systems software.

This guide walks through the full process for first-time competitors: how qualification works, what judges look for, how to prepare your project, and what to do with your research after the competition ends.

How Regeneron ISEF Qualification Works for First-Time Competitors

You cannot apply to Regeneron ISEF directly. Every competitor must first win a place at an affiliated fair, which is a regional, national, or international science fair that Society for Science has approved to send finalists to ISEF. There are over 600 affiliated fairs worldwide. Winning first place at an affiliated fair does not always guarantee an ISEF spot. Each fair is allocated a set number of finalist positions based on its size and category.

The qualification path follows a clear sequence:

1. Find your nearest affiliated fair using the official Society for Science fair finder at societyforscience.org.

2. Register for that fair and submit your project according to its own deadlines and rules.

3. Compete at the local or regional level and earn one of the allocated ISEF finalist positions.

4. Complete the ISEF student registration forms, including all required regulatory approvals for your project type.

5. Attend ISEF, present your project to judges, and participate in the full competition week.

The regulatory approval step is where many first-time competitors lose time. If your project involves human subjects, vertebrate animals, potentially hazardous biological agents, or controlled substances, you need prior approval from a qualified scientific reviewer before you begin experimentation. Society for Science publishes its International Rules for Precollege Science Research, which sets out exactly which project types require which approvals. Read those rules before you start your experiment, not after.

What ISEF Judges Actually Evaluate

ISEF judges score projects across six criteria: creative ability, scientific thought, thoroughness, skill, clarity, and dramatic presentation. Each criterion is weighted, and scientific thought carries the most influence. A project with modest results but rigorous methodology will outscore a project with impressive results and weak reasoning.

Judges at ISEF are working scientists, engineers, and researchers. They have seen thousands of projects. What impresses them is not complexity for its own sake. It is the ability of a student to explain exactly what question they asked, why it matters, how they designed their experiment to answer it, what they found, and what the limits of their conclusion are. That last point, acknowledging limitations, is something many first-time competitors skip. Judges notice when it is missing.

Your abstract is also a scored component. ISEF requires a structured abstract of no more than 250 words, submitted in advance. It must cover the purpose, procedure, data, and conclusions of your project. Treat it as a standalone document. A judge reading only your abstract should understand what you did and why it matters.

If you are working to turn your project into a formal research paper alongside your ISEF preparation, The Young Researcher Complete Guide covers the full process of structuring student research from question to submission.

How to Structure Your ISEF Research Paper

Not all ISEF categories require a formal research paper, but writing one strengthens your project documentation and prepares you for post-competition publication. A well-structured paper also forces you to think through your methodology more carefully, which improves your verbal presentation to judges.

A standard student research paper for ISEF follows this structure:

1. Title and abstract. The title should describe the independent and dependent variables. The abstract summarises the full study in 250 words or fewer.

2. Introduction. State the research question, review relevant existing literature, and explain the hypothesis. Every claim in this section needs a citation.

3. Methods. Describe every step of your procedure in enough detail that another researcher could replicate it. Include materials, sample sizes, controls, and any statistical tests you planned to use before collecting data.

4. Results. Present your data clearly. Use tables and figures where they add clarity. Do not interpret here. Report what you found.

5. Discussion. Interpret your results. Compare them to the literature you reviewed. Address limitations honestly. Suggest future directions.

6. References. Use a consistent citation format. APA and MLA are both accepted by most student journals.

If you want to understand how journals evaluate papers at this level before you submit anywhere, reading How To Read A Journals Submission Guidelines will save you significant revision time.

Publication Compass is a platform built for exactly this stage. You upload your draft, receive structured feedback on your methodology and writing, and get matched to journals that publish student research in your field. It does not replace your own thinking, but it shortens the gap between a rough draft and a submission-ready paper.

Choosing the Right Journal After ISEF

Winning at ISEF or placing well is not a requirement for publication. Many ISEF projects, including those that did not advance past the regional level, have been published in peer-reviewed student journals. What matters to editors is whether the research question is clear, the methodology is sound, and the conclusions are supported by the data.

Several journals specifically publish high school research across science disciplines. The Journal of Emerging Investigators publishes original research from middle and high school students and provides peer review by graduate students and faculty. Its scope covers biological and physical sciences. The National High School Journal of Science accepts submissions across STEM fields and is free to submit to. The Journal of High School Science covers a similar range and provides detailed reviewer feedback to student authors.

For a detailed breakdown of what JEI looks for and how to format your submission, the Journal Of Emerging Investigators Submission Guide covers the process step by step. If your project falls within the scope of NHSJS, the National High School Journal Of Science Submission Guide explains their specific formatting and review requirements.

If you are ready to identify the right journal for your specific project and get feedback on your draft before submitting, you can join the Publication Compass waitlist to be among the first to use the platform when it opens.

Preparing Your Display and Oral Presentation

ISEF judges spend roughly ten minutes at each project board during initial judging rounds. That time includes reading your display, asking questions, and forming a preliminary score. Your display board must communicate your project clearly at a glance.

Society for Science sets specific size requirements for display boards: a maximum of 122 cm wide, 274 cm tall, and 76 cm deep. Your board should follow the same structure as your paper: question, background, hypothesis, methods, results, discussion, and conclusion. Use visuals where possible. Graphs and photographs communicate faster than paragraphs.

For the oral component, prepare a two-minute opening summary that covers what you studied, how you studied it, and what you found. Then prepare for questions. Judges will probe your understanding of your own methodology. Common questions include: Why did you choose that sample size? What would change if you repeated this with a different population? What is the biggest weakness in your design? Practice answering these out loud, not just in your head.

What Happens After the Competition

ISEF week ends with an awards ceremony. Grand Awards are given by category. Special Awards are given by affiliated organisations, including government agencies, universities, and scientific societies. Many Special Award sponsors offer scholarships, internships, or laboratory visits as part of their prizes.

Regardless of how you place, your research has value beyond the competition. ISEF participation demonstrates independent scientific inquiry, which is meaningful on college applications. Published research demonstrates it even more clearly. Admissions readers at universities see ISEF on many applications. A published paper in a peer-reviewed student journal is far less common and carries distinct weight.

If a parent or educator is supporting a student through this process, the Parents Guide Helping Child Publish Research explains how to support the research and publication process without taking it over.

Frequently Asked Questions About Regeneron ISEF

Can a first-time competitor win at Regeneron ISEF?

Yes. First-time competitors win awards at ISEF every year. Prior ISEF experience is not a scoring criterion. Judges evaluate the project on its scientific merit, not the student's competition history. Strong methodology, clear communication, and honest analysis of limitations are what separate high-scoring projects from the rest.

How long does it take to prepare a competitive ISEF project?

Most competitive projects take six to twelve months from initial question to final presentation. The research design and data collection phase is the longest. Projects that rush the experimental phase often have methodological gaps that judges identify quickly. Starting at least one full academic year before your target ISEF is the standard recommendation from Society for Science.

Do I need a mentor or supervisor to compete?

ISEF rules require that projects involving certain regulated materials or procedures have a qualified scientist supervise the work. For most projects, a mentor is not required by the rules but is strongly beneficial in practice. A mentor with domain expertise can help you refine your research question, identify weaknesses in your design, and review your paper before submission.

Can I publish my ISEF project in a journal before the competition?

Yes. Publishing before ISEF does not disqualify your project. Some students submit to student journals during the same period they are preparing for affiliated fairs. If you do publish before competing, disclose this on your ISEF forms. Judges view prior publication as a positive signal of research quality, not a conflict.

What is the difference between a Grand Award and a Special Award at ISEF?

Grand Awards are given by Society for Science and are category-specific. They rank the top projects within each of the 22 competition categories and carry cash prizes. Special Awards are given by external organisations, including NASA, the American Psychological Association, and various universities. Special Awards often come with additional prizes such as scholarships, trips, or internship offers, and are judged separately from Grand Awards.

The Next Step

Regeneron ISEF rewards preparation. The students who perform well are not always the ones with the most sophisticated equipment or the most surprising results. They are the ones who understood their own research deeply, documented it carefully, and could explain it clearly to a working scientist in ten minutes. That standard is achievable for a first-time competitor who starts early and takes the process seriously.

If your project is heading toward a paper, treat that paper as seriously as the display board. The habits of clear scientific writing, precise citation, and honest discussion of limitations will serve you well beyond any single competition.
