If all girls, boys complete secondary education, 420m. people could be lifted out of poverty

Education transforms lives. As United Nations Messenger of Peace Malala Yousafzai once said: “one child, one teacher, one book and one pen can change the world”. Nelson Mandela rightly called education “the most powerful weapon which you can use to change the world.”

Long before I served at the United Nations or held public office in my own country, I was a teacher. In the slums of Lisbon, I saw that education is an engine for poverty eradication and a force for peace.

Today, education is at the heart of the Sustainable Development Goals.

We need education to reduce inequalities and improve health.

We need education to achieve gender equality and eliminate child marriage.

We need education to protect our planet’s resources.

And we need education to fight hate speech, xenophobia and intolerance, and to nurture global citizenship.

Yet at least 262 million children, adolescents and youth are out of school, most of them girls.  Millions more who attend school are not mastering the basics.

This is a violation of their human right to education. The world cannot afford a generation of children and young people who lack the skills they need to compete in the 21st century economy, nor can we afford to leave behind half of humanity.

We must do far more to advance Sustainable Development Goal 4, to ensure inclusive and equitable quality education and promote lifelong learning opportunities for all.

Education can also break and reverse cycles of intergenerational poverty. Studies show that if all girls and boys complete secondary education, 420 million people could be lifted out of poverty.

Let us prioritize education as a public good; support it with cooperation, partnerships and funding; and recognize that leaving no one behind starts with education.
