Low pay. Lack of respect. Being asked to achieve the impossible with not enough time, resources or training to do your best. Teachers around the world reveal the challenges they face – and why they keep at it despite everything.

Open the door of classrooms around the world and you’ll find a surprising range of challenges – as well as some truly incredible teachers dedicated to changing children’s lives.

Volunteer Jo Doyne is based in western Rwanda, supporting teachers to provide appropriate teaching to children with special needs. She talks to us about her work with Ngwino Nawe, a special needs school.
