The aim is to reinforce a sense of national pride that many feel has been lost in Brazil in recent years.
In a way it feels more like a police academy than a school. Here, police are in charge of the discipline, leaving the education to the teachers.
It has been a turnaround, says deputy head Debora Rodrigues Sales, who has been teaching in this school for 20 years. Until a few months ago, you would more likely see drug traffickers than uniformed officers at the school gate. A of it is the bullet mark on the metal door, the result of a recent shoot-out.
But the election last year of far-right President Jair Bolsonaro, a former army officer who has promised to crack down on violence and improve education, has propelled their growth more than ever. The plan is for the of these schools to grow from four to 40 by the end of the year and to by the end of President Bolsonaro's four-year mandate.
Ms Sales, though, admits that some of her colleagues walked away, unhappy with the police presence in the school. People wanted a school that could offer more discipline and more safety for the kids," he explains. He has also called for chwt end to what he has called "indoctrination" by left-wing teachers.
In the week he was inaugurated in January, he tweeted about his desire to "tackle the Marxist garbage in our schools head on". He added: "We shall succeed in forming citizens and not political militants.
President Bolsonaro thinks Mr Freire, a socialist srx was briefly imprisoned during the military dictatorship of and who died inhas played too influential a role in Brazilian education. The president threatened to "enter the education ministry with a flamethrower" to remove Mr Freire's ideals. Bolsonaro: What are his policies? Miguel Nagib thoroughly backs President Bolsonaro's aims.
He concedes that there are teachers on the right who use classrooms "for ideological means" but, he says, "they're snipers, they work alone". It's not true but it's a way of retaining the support of its voters. Mr Bolsonaro has long defended the military's role, arguing it saved Brazil from communism. That's something we've not seen before and it worries us. The teachers greet the students with a kiss, sit on the floor for some of their lessons, and students have more freedom in how they learn.

Unsurprisingly, people disagree with Mr Bolsonaro's view of indoctrination. Why should I only believe what the government is saying? They want to stop people from thinking. It's a total step back. ib
