As the world's population grows, more resources and policies are needed to make sure that students everywhere get a good education. The world needs two million teachers and four million new classrooms to make sure every student can get an education. Full access to quality education is the first step to achieving sustainable development, poverty eradication, gender equality and women's empowerment. Let's make the sound investment in quality education by ensuring that primary and secondary schools are free for every child by 2030.
