Globally we need more well-trained and motivated teachers.Good teachers can help ensure that every child learns to their full potential from an early age and enters adult life well-equipped to be active citizens and support the development of their community and country. Many countries do not have enough teachers, let alone enough teachers who have received sufficiently high quality pre- and in-service training and access to continuing professional development. This paper first provides detail about the context and scale of the challenge. It then outlines five broad issues that need addressing if we are to prepare, recruit and support enough teachers, with appropriate skills, to educate every child – including those with disabilities.
