The system produced another striking result this weekend, when Iran’s five-member team won five gold medals at the International Olympiad on Astronomy and Astrophysics in Hanoi, securing the world championship for a third consecutive year.
The achievement is part of a much longer record. Iran has spent decades identifying exceptional schoolchildren, training them intensively and directing them toward mathematics, physics, engineering, computer science and other technical disciplines.
International victories bring prestige, but the students themselves are arguably more valuable. They form part of the human capital on which Iran’s universities, technology sector and some of its most strategically important industries depend.
That is also where the system encounters its central contradiction. Iran has proved remarkably effective at finding and developing scientific talent. It has had considerably more difficulty keeping it.
A pipeline for elite science
Iran’s Olympiad program is not simply a collection of international competitions. It is the upper end of an extensive system for identifying gifted students while they are still in school.
The Young Scholars Club organizes national Olympiads across mathematics, physics, chemistry, biology, informatics, astronomy and other disciplines, with many successful competitors coming through Iran’s selective schools for gifted students, commonly known as Tizhooshan.
Students who advance through successive rounds receive specialized instruction well beyond the standard school curriculum. A small number are eventually selected for international teams and spend months preparing to compete against the strongest students from other countries.
Participation has grown sharply. Some 121,000 students entered Iran’s scientific Olympiads in the Iranian year ending in March 2026, up from 87,000 the previous year, an increase of about 40% and the highest participation in a decade.
There are substantial incentives for those who reach the top. International gold medalists in established scientific Olympiads can receive exemptions from Iran’s fiercely competitive national university entrance examination, or Konkoor, giving them a privileged route into the country’s leading universities and technical programs.
The results extend well beyond astronomy. Iran has repeatedly won medals in mathematics, physics, chemistry, biology and informatics, including some of the highest placements in international competition.
For the state, those performances provide visible evidence that sanctions and international isolation have not prevented Iran from cultivating world-class scientific ability.
There is substance to that claim. Repeated success shows that Iran has developed an effective mechanism for discovering exceptional students and preparing them to compete at the highest level.
But Olympiad results demonstrate concentrated excellence rather than the overall strength of Iran’s education system. A small group of highly selected students can receive intensive training and state support while ordinary schools face shortages, unequal resources and deteriorating economic conditions.
More revealing is what happens to the medalists after they leave school.
From Olympiad medals to strategic universities
Research into the careers of International Mathematical Olympiad medalists illustrates how concentrated Iran’s elite science pipeline has become.
Among 75 Iranian mathematics medalists whose undergraduate education could be established in one study covering medalists from 1986 to 2005, 71 attended Sharif University of Technology and the other four went to the University of Tehran.
The concentration provides a direct link between Iran’s Olympiad system and two of the institutions at the center of its scientific establishment.
Sharif is widely regarded as Iran’s leading engineering and technical university. It has also had longstanding connections with research areas tied to Iran’s nuclear, missile and defense sectors.
Several research bodies located at the university have been sanctioned by the United States under authorities targeting proliferation of weapons of mass destruction.
European sanctions have gone further, citing Sharif’s cooperation with organizations involved in Iran’s ballistic missile program and its connections with entities associated with nuclear research and uranium enrichment.
The University of Tehran has its own history of research touching sensitive fields. Its academics have worked in areas relevant to missiles, drones, aerospace technology and nuclear science, as well as projects connected to Iran’s space program.
The university also played an early role in the development of Iran’s nuclear infrastructure. Its Atomic Center, established in the 1960s around a US-supplied research reactor, was transferred to the Atomic Energy Organization of Iran in 1974 and became the Tehran Nuclear Research Center.
None of this means Olympiad winners are systematically recruited into nuclear or missile programs. There is no evidence of such a direct mechanism, and the overwhelming majority of teaching and research at Iran’s major universities is civilian.
The connection is one of human capital.
The mathematics, physics, computing and problem-solving skills cultivated through Olympiad training are also essential to artificial intelligence, aerospace engineering, advanced computing, cybersecurity, nuclear science and missile development.
The universities that attract Iran’s strongest students supply engineers and researchers to a broad range of institutions, from civilian technology firms and research centers to parts of the defense and nuclear establishment.
For a heavily sanctioned state, such expertise has particular value.
Restrictions on imports, technology transfers, investment and international research collaboration make indigenous scientific capacity more important. Iran may struggle to obtain certain foreign technologies or advanced equipment, but scientific expertise developed domestically is considerably harder to restrict.
The Olympiad system therefore serves a purpose beyond medals. It identifies unusually capable students early, concentrates resources on their development and helps direct them toward disciplines important both to Iran’s economy and to sectors the state considers strategically vital.
But producing that talent does not mean Iran gets to keep it.
The talent drain
Studies of Iranian Olympiad medalists suggest that a substantial proportion eventually build their lives elsewhere.
Among 82 Iranian International Mathematical Olympiad medalists whose current location could be established in one study, 49 — around 60% — were living abroad.
The same research found a strong relationship between studying abroad and permanent migration. More than 70% of Olympiad medalists who pursued either undergraduate or doctoral education overseas eventually remained abroad, while those educated entirely in their home countries were considerably more likely to stay.
Other figures circulated in Iran have been even more dramatic.
In 2022, the secretary-general of the Iranian Talent Association said that 82 or 83 members of a group of 86 Olympiad medalists tracked by the organization had emigrated, arguing that inadequate support for talented young people inside Iran was a major factor.
Iranian officials disputed that figure and cited research suggesting that a majority of a much larger group of international Olympiad winners still lived in Iran or had returned after studying abroad.
The samples and methodologies differ, making the figures difficult to compare directly. But the broader problem of migration among Iran’s most highly educated young people is widely acknowledged.
For students who spend years preparing to compete at international level, the contrast between opportunities inside and outside Iran can be stark.
At home they face inflation, currency depreciation, weakened salaries, limited research funding, shortages of modern laboratory equipment, bureaucratic restrictions and obstacles to international scientific cooperation.
Sanctions deepen many of those pressures by limiting access to equipment, software, financing and research partnerships.
The qualities that make these students valuable to Iran also make them unusually mobile.
An international Olympiad medal is a credential recognized by universities around the world. A student emerging from Sharif with an Olympiad background can compete for places at elite graduate schools, research laboratories and technology companies abroad.
The investment that makes the student valuable inside Iran therefore also increases their ability to leave it.
Maryam Mirzakhani remains the best-known example.
She won mathematics Olympiad gold medals for Iran as a teenager, studied at Sharif and later moved to the United States, where she became a professor at Stanford University and the first woman to win the Fields Medal.
Her career demonstrated both sides of Iran’s Olympiad system: its ability to identify exceptional talent and its difficulty retaining the long-term scientific benefits of that talent.
That does not mean every medalist leaves. Many remain in Iran and contribute to universities, research centers, technology companies and industry. Some who study overseas also maintain scientific ties with Iran or eventually return.
But the loss carries disproportionate weight when those leaving represent some of the most intensively selected and trained scientific talent the country produces.
The Olympiad paradox
Iran’s investment in scientific Olympiads therefore remains rational even when some of its most successful products emigrate.
The system discovers talent that might otherwise go unnoticed, raises scientific standards, gives exceptional students opportunities and produces genuine international achievements.
It also develops scientists and engineers in disciplines Iran considers essential to its economic and technological future.
Under sanctions, that logic becomes even stronger. When technology, equipment and capital are difficult to import, investing in people becomes one of the few capabilities a country can develop largely from within.
Yet that strategy depends on more than discovering talented teenagers.
Iran can identify an exceptional student at 15, provide intensive training, waive the university entrance examination, send them to Sharif and celebrate when they defeat competitors from dozens of countries.
What the Olympiad system cannot provide is the research environment, professional freedom, economic security and long-term career prospects that determine where that student chooses to live at 25 or 35.
That gap can turn Iran’s investment into an unintended subsidy for institutions abroad.
Iranian families, schools and public institutions bear much of the cost of discovering and developing globally competitive students. Foreign universities, laboratories and companies can later recruit scientists and engineers whose foundational training has already been completed.
For Iran, the implications extend beyond academia. The same talent that can strengthen a university laboratory or technology company can also contribute to aerospace, artificial intelligence, nuclear research and other strategically important sectors.
This weekend’s five astronomy gold medals show that the first part of Iran’s system continues to work exceptionally well. For a third consecutive year, Iranian students have demonstrated that they can compete with the best young scientific talent in the world.
The harder measure of success comes years later: whether Iran can offer those students a future compelling enough to keep the talent it worked so hard to discover.
