These prizes, contributed by scientific societies and industry partners, underscored the event's goal of equipping promising young researchers. Over time, the fair evolved into a global competition, expanding its reach beyond U.S. borders.

Key Milestones and Sponsorship Changes

The International Science and Engineering Fair (ISEF) began its expansion in the late 1950s, transitioning from a national to an international competition when , , and sent the first non-U.S. participants in 1958, joining 280 American finalists in . This internationalization continued into the 1960s, with the event officially renamed the International Science Fair in 1965 to reflect its growing global scope and further renamed the International Science and Engineering Fair in 1971. By the 1970s, participation had surged, reaching 404 finalists in 1970 from 219 affiliated fairs, and growing to 458 exhibitors by 1979, driven by increased regional competitions across the U.S. and abroad. The saw further acceleration, with 754 finalists in 1990 from 398 affiliated fairs, alongside heightened corporate involvement that boosted funding and visibility for the program. Sponsorship evolved significantly in the late 1990s when became the title sponsor in 1997, rebranding the event as the Intel ISEF and supporting its expansion to over 75 countries, regions, and territories through enhanced prizes and resources until 2019. In December 2019, announced its role as the new title sponsor starting in 2020, committing approximately $24 million over five years to sustain and grow the competition amid the transition from Intel. This shift marked Regeneron ISEF, with the company later extending support through an additional $34 million commitment over five years announced in 2023. The prompted major adaptations, including the full cancellation of the 2020 in-person event due to travel and gathering restrictions, affecting what would have been the first Regeneron ISEF. The edition proceeded virtually, enabling remote participation and judging for finalists worldwide.

Use of generative tools must be disclosed and cited, ensuring the project reflects the student's independent work; unauthorized or excessive reliance is prohibited.

Qualification Process

The qualification process for the International Science and Engineering Fair (ISEF) operates through a multi-tiered system designed to identify exceptional student research from a global pool. It begins at the school or club level, where high school students develop and present original projects at local science fairs. Top performers from these initial competitions advance to regional or state-level events, which further narrow the field by selecting outstanding entries based on scientific merit, originality, and presentation quality. Winners from these intermediate stages proceed to one of approximately 360 ISEF-affiliated fairs worldwide, sanctioned by the Society for Science. At these affiliated competitions—typically held between January and April—judges evaluate projects across categories, nominating the top performers to ISEF. Each affiliated fair selects a predetermined number of finalists, usually 1 to 10 projects depending on the fair's size and regional population, ensuring representation from diverse areas. This step draws from over 175,000 high school participants annually in affiliated fairs alone, with about 1,600 students ultimately selected as finalists for the international event. Viewed across the entire pipeline, including the school and local levels, millions of students worldwide compete in initial science fairs each year, feeding into the affiliated fairs and making ISEF qualification highly selective. International students follow the same pathway via affiliated fairs in their countries or regions, with the Society for Science supporting new affiliations to expand access where local structures are limited. Nominated finalists must then complete an application process overseen by the ISEF Scientific Review Committee (SRC). This includes submitting an official abstract summarizing the project (limited to 250 words), a detailed research plan outlining methodology and safety protocols, and required forms such as Form 1 (for the research plan), Form 1A (for adult sponsor information), and category-specific checklists for ethical compliance. Deadlines for these submissions vary by affiliated fair but generally fall in late winter or early spring—often by February—for the May ISEF event, allowing time for SRC review and approval before travel arrangements. All materials must adhere to ISEF international rules to confirm the research's originality, conducted within 12 continuous months (not exceeding 18 months prior to the competition), and free of plagiarism or unsafe practices.

Risk assessments are required for any use of chemicals, biological agents, or other potentially hazardous materials, detailing safe handling, storage, and disposal procedures in compliance with local, state, and federal regulations. For biological agents, projects involving potentially hazardous biological agents (PHBAs) necessitate approval from an Institutional Biosafety Committee (IBC) and, for Biosafety Level 2 (BSL-2) agents, supervision by a Qualified . Hazardous substances, including toxic chemicals or pathogens, cannot be released into the , and all waste must be disposed of according to established guidelines. Ethics rules emphasize the protection of human subjects and vertebrate animals in research. For human participant studies, Institutional Review Board (IRB) approval is mandatory prior to any interaction, such as surveys, observations, or experiments, with IRBs comprising at least an educator, school administrator, and a medical or mental health professional. Informed consent must be obtained from all participants, including written parental permission and child assent for minors, outlining potential risks, benefits, voluntary nature, and the right to withdraw at any time; waivers are permitted only for minimal-risk, anonymous studies. Prohibited activities include medical diagnoses, administration of medications, blood draws (except from the student researcher themselves), and use of unapproved diagnostic tools. For vertebrate animals, Institutional Animal Care and Use Committee (IACUC) approval is required for studies conducted at regulated research institutions, while local Scientific Review Committees (SRCs) oversee school, home, or field-based work, often including a veterinarian. Animal care must follow the "Four Rs" (Replacement, Reduction, Refinement, Respect), ensuring humane treatment in clean, ventilated environments with daily monitoring, adequate nutrition, and veterinary consultation for any health issues; no more than slight or momentary pain/distress is allowed, and euthanasia must be performed by qualified professionals. Projects involving endangered species, invasive organisms, toxicity testing, or predator-prey experiments are strictly prohibited. Intellectual property guidelines mandate that all projects represent original work, conducted independently or under qualified , with clear delineation of contributions from mentors, collaborators, or prior in the project documentation. , fabrication of data, or unauthorized use of in generating results is forbidden and can result in disqualification. Proper citations are required for all sources, including mentors' guidance, published works, patents, or unpublished data, ensuring respect for copyrights and intellectual contributions.

Judging Process

Criteria and Evaluation Methods

Projects at the International Science and Engineering Fair (ISEF) are evaluated using a structured rubric that differs slightly between and categories, with each totaling 100 points to ensure a comprehensive assessment of originality, rigor, and communication. For projects, the criteria include (10 points), design and (15 points), execution (20 points), and (20 points), and (35 points, split as 10 for the poster and 25 for the interview). projects follow a parallel structure: (10 points), design and (15 points), execution (20 points), and (20 points), and (35 points). These criteria emphasize the project's scientific or engineering merit, focusing on clear purpose, methodical approach, data-driven results, innovative potential, and effective conveyance of findings. The evaluation process unfolds in two primary stages to allow for both independent review and interactive assessment. Initially, judges conduct a pre-interview review of the project's abstract, display board, student notebook, and required forms (such as Form 1C for continuation projects and Form 7 for risk assessment), enabling an preliminary evaluation of the project's foundation and documentation. This is followed by a 15-minute in-person interview, where finalists discuss their work with judges, addressing questions on methodology, challenges, and implications to demonstrate depth of understanding. Category-specific scoring ensures alignment with disciplinary standards, such as biological versus physical sciences. Quantitative aspects of projects receive particular scrutiny under the execution criterion, where judges assess the rigor of data collection, analysis, and reproducibility, including the application of appropriate statistical methods to validate results. For instance, experimental projects must demonstrate robust handling of variables, error analysis, and statistical tools to support conclusions, prioritizing validity over mere volume of . This focus ensures that claims are substantiated through reliable quantitative evidence rather than anecdotal observations. To promote fairness, the judging process incorporates multiple reviews by at least two judges per project, with conflicts of interest explicitly addressed through requirements and recusal protocols. Scoring is based solely on the current year's contributions for multi-year projects, and both individual and team entries are evaluated using the same standards without differentiation, minimizing biases related to project scale or collaboration. The overall methodology is designed to be transparent, with judges attesting to ethical conduct and decisions finalized through consensus where needed.
