The world has made substantial progress over recent decades in expanding access to education and helping more young people complete school. Yet according to UNESCO’s Global Education Monitoring Report 2026, if current trends continue, it could take until 2105 for 95 percent of young people worldwide to finish upper-secondary education. This projection stands as a stark reminder of how far the global community remains from the ambitious goals set for universal secondary completion.
Progress in School Completion Since 2000
Completion rates have risen steadily across all levels of education. Between 2000 and 2024, the global primary completion rate increased from 77 percent to 88 percent. Lower-secondary completion moved from 60 percent to 78 percent over the same period. Upper-secondary completion showed the most dramatic relative gain, climbing from just 37 percent to 61 percent. These improvements reflect expanded enrolment, reduced barriers in many countries, and greater attention to keeping children in school longer.
Despite these gains, the absolute numbers reveal persistent gaps. Nearly four in ten young people still leave the education system before completing upper-secondary education. The pace of improvement at this level has averaged roughly one percentage point per year since 2000. At that rate of expansion, reaching the 95 percent threshold would require another eight decades.
The Challenge of Late Entry and Grade Repetition
A significant factor slowing overall progress is the gap between timely completion and eventual completion. Many children, particularly in lower-income countries, enter school late or repeat grades. Globally, the difference between timely and eventual lower-secondary completion stands at around four percentage points. In low-income countries, that gap widens to nine percentage points. These delays mean that large numbers of students reach the final grades years after the intended age, stretching the time needed for systems to achieve high completion rates.
There has been encouraging movement on one related front. High rates of grade repetition have declined substantially since 2000, falling by 62 percent in primary education and by 38 percent in lower-secondary education. This reduction helps explain a seeming paradox in the data: out-of-school rates have stagnated or even risen slightly in recent years, while completion rates continue to improve. Fewer children are held back, allowing more of those who remain in school to finish their studies.
Rising Numbers of Children Out of School
The 2026 report highlights another concerning trend. After falling by 33 percent between 2000 and 2015, the global out-of-school population has increased for a seventh consecutive year. In 2024, an estimated 273 million children, adolescents and youth were out of school. This means that one in six school-age young people worldwide remains excluded from education. Population growth, ongoing crises and constrained education budgets have contributed to the reversal of earlier gains.
The out-of-school challenge is concentrated at the secondary level. Of the total, a large share consists of adolescents and youth who should be in lower- or upper-secondary education. This reinforces the difficulty of achieving near-universal secondary completion within any near-term timeframe.
Why Upper-Secondary Completion Remains the Hardest Goal
Primary and lower-secondary education have seen faster relative progress in many regions. Upper-secondary education, which typically covers the final years of secondary schooling, faces steeper obstacles. These include higher opportunity costs for families, fewer schools in rural areas, weaker relevance of curricula to local labour markets, and greater pressure on adolescents to contribute to household income. In low-income countries, the timely upper-secondary completion rate remains particularly low, with only around one in five young people finishing on schedule and roughly one in four eventually completing.
Gender gaps have narrowed significantly at primary and secondary levels on average. In some countries, girls have not only caught up with boys but surpassed them in completion rates thanks to targeted policies. Wealth and location, however, continue to drive deep inequalities. Children from the poorest households and those living in rural areas face far lower chances of finishing secondary school than their wealthier or urban peers.
Implications for Global Education Goals
The projection that 95 percent upper-secondary completion may not arrive until 2105 challenges the credibility of successive global education agendas. Earlier targets focused first on universal primary access, then on primary completion, and later on secondary completion. Each time, ambition rose faster than the capacity of education systems to expand and retain students. The result has been repeated shortfalls against deadlines, including the 2030 Sustainable Development Goal targets.
This does not mean that progress has been meaningless. Hundreds of millions more children are in school today than at the turn of the century. Enrolment in primary and secondary education has grown by hundreds of millions since 2000. Pre-primary and post-secondary participation have expanded even more rapidly in percentage terms. The challenge lies in converting access into successful completion for the final stretch of secondary education.
Pathways Toward Faster Progress
The report underscores that faster change is possible. Some countries have achieved dramatic reductions in out-of-school rates and sharp increases in completion by focusing on early childhood preparation, reducing repetition, improving school quality, and addressing the specific barriers faced by disadvantaged groups. Policies that support late entrants, provide flexible pathways for over-age students, and link secondary education more closely to skills and employment can accelerate gains.
Reducing the lag between timely and eventual completion is especially important in lower-income settings. Addressing the root causes of late entry and high repetition rates would compress the timeline needed to reach high levels of completion. Sustained financing, stronger data systems, and greater attention to equity will also be essential.
Looking Beyond Current Trends
The 2105 projection is not inevitable. It is a reflection of the trajectory based on recent rates of improvement. Changes in policy, investment and prioritisation can alter that trajectory. As the global community approaches the 2030 deadline and begins shaping the post-2030 education agenda, the findings of the 2026 Global Education Monitoring Report offer a clear message. Expanding access remains necessary but is no longer sufficient. The harder and more decisive task is ensuring that the majority of young people not only enter secondary school but complete it successfully and on a realistic timeline.
Without accelerated progress, generations of young people will continue to leave the education system without the qualifications that open pathways to further learning, decent work and fuller participation in society. The long road to 95 percent upper-secondary completion can be shortened, but only through deliberate and sustained effort that matches the scale of the remaining challenge.
