In 2015, Brazil's upper secondary education system was falling short by every measure. School days lasted just four hours. And for too many young people, the classroom felt entirely disconnected from their futures. By age 19, barely 55 percent of students had graduated, nearly three in ten were two or more years behind their expected grade, and only 21 percent met minimum proficiency in Portuguese — just 3 percent in mathematics. That was the starting point for one of the most far-reaching education reforms in the region.
It was against this backdrop that Brazil launched one of the most ambitious upper secondary education reforms in Latin American history.
What followed was not a smooth policy rollout. It was a ten-year process shaped by political change, a pandemic, public opposition, and mid-course correction — also, through all of it, measurable progress. Brazil's experience offers a window into what it takes to reform a secondary education system at scale.
Making school make sense — and keeping students there
At its core, the reform tackled a deceptively simple problem: students were leaving because school no longer felt relevant to them. The new model introduced flexible learning pathways, expanded instructional time, and promoted full-time schooling, offering students more choice, more structure, and a clearer sense of where their education was leading.
The reform moved forward under conditions that would have stopped many efforts. Eight ministers of education came and went between 2016 and 2025. COVID-19 forced months of school closures across the country. And yet, through all of it, something tangible was being built: students were staying longer and progressing more smoothly.
Between 2015 and 2023, promotion rates in state schools climbed from roughly 80 percent to 90 percent. Grade repetition was cut in half. The share of 19-year-olds who had completed upper secondary school rose sharply, from 55 to 71 percent, while age-grade distortion fell from 30 to 21 percent.
These are not abstract statistics. They represent teenagers who stayed in school when earlier systems would have lost them, and families who no longer had to watch their children give up on education altogether.
More time in school changed everything
Of all the reform's components, one moved faster — and farther — than any other: time.
In 2015, most Brazilian high school students spent just four hours a day in class. By 2023, 62 percent of state schools had extended the instructional day to at least five hours, up from 27 percent eight years earlier. Enrollment in full-time schools — defined as seven or more hours of instruction daily — nearly tripled, rising from about 5 percent to 17 percent.
For teachers and principals, the shift was tangible. Longer school days created space for lesson planning, arts, sports, tutoring, shared meals, and the kind of relationships that keep young people engaged. Research across Latin America consistently finds that full-time schooling reduces dropout and improves learning outcomes, particularly for students from disadvantaged backgrounds.
This expansion was driven by targeted federal financing and reinforced by a US$250 million World Bank operation that prioritized schools serving the most vulnerable students, helping states manage the real cost of longer school days.
Time, it turns out, was the most tractable lever the reform had — and the most visible to the families and communities it was meant to serve.

Learning outcomes improved, but classrooms proved harder to change
Learning did improve, particularly before the pandemic, though not at the pace that policymakers had hoped.
Between 2015 and 2019, the share of students reaching minimum proficiency in Portuguese rose from 21 to 31 percent. In mathematics, proficiency climbed from 3 to 5 percent. Both indicators declined modestly after COVID-19 — to 29 percent in Portuguese and roughly 4 percent in mathematics by 2023 — but remained above their starting points.
Brazil's overall Education Development Index rose from 3.5 to 4.1, still well short of the national target of 4.9.
Why did learning prove so much harder to shift than enrollment or attendance? The answer is one that education systems around the world grapple with: changing what happens inside classrooms is far more complex than changing school schedules. Structural reforms can be mandated; pedagogical transformation has to be cultivated.
Curriculum reform: coherent in design, difficult in practice
The most contested element of the reform was its curriculum overhaul. Anchored in Brazil's National Common Core Curriculum (BNCC), the new model reduced the number of mandatory subjects and introduced flexible learning pathways — academic and technical — intended to make school feel more purposeful for students with different ambitions and trajectories.
The design was modern and aligned with international best practice. The implementation, however, stretched state systems to their limits. Teachers frequently lacked adequate training. Schools struggled to offer meaningful pathway options. And national assessments — Saeb and Enem — remained misaligned with the new curriculum, blunting the incentive for teachers to change how they taught.
A 2023 nationwide UNESCO survey conducted during the reform's implementation captured the scale of the frustration: most school managers reported feeling unprepared, 74 percent of teachers doubted whether the reform was delivering real benefits, and students noticed little change in their day-to-day school experience.
The gap between what the reform promised on paper and what teachers and students experienced in practice became its defining tension.
Listening, adjusting, and rebuilding trust
In 2023, the federal government paused to take stock. It launched a far-reaching public consultation — engaging students, teachers, parents, and administrators across the country, both online and via WhatsApp — that made one thing unmistakably clear: the balance between flexibility and structure had been badly miscalibrated.
The response was a new law that recalibrated rather than reversed the reform. The mandatory common curriculum was expanded to 2,400 hours; flexible pathways were reduced to 600 hours; all BNCC components were reinstated; and the rules governing pathway design were tightened.
This was not a retreat, but an act of institutional learning — a signal that the reform was capable of evolving in response to evidence and to the people it was meant to serve. Over a decade, Brazil demonstrated that legitimacy in education reform is not granted once and held forever; it must be actively renewed.
What Brazil's journey teaches the world
First, design for complexity. Curriculum reform does not succeed on the strength of a policy document alone. It requires teacher training, instructional materials, aligned assessments, and time — and neglecting any one of these will slow progress across all of them.
Second, measure what matters. When accountability systems lag behind reforms, classroom change will lag too. Assessment frameworks must evolve alongside the policies they are meant to track.
Third, build resilience through dialogue. The public consultations and legislative adjustments that marked Brazil's reform were not signs of weakness or political capitulation. They were the reason the reform survived — and why it continues to move forward.
Ten years on, Brazil's experience is a reminder that education reform succeeds not merely when school structures change or instructional hours are added, but when students feel that school is worth staying for, teachers feel genuinely supported, and the system itself has the humility to learn and adapt as it goes.
