But we've got to invest in teacher professional development because that is how we're really going to turn things around. When we talk about the quality of teaching, people say we should raise the standard for beginning teachers. That's all very well and good, but 10 years from now, the majority of teachers in our classrooms will be teachers that are already in our classrooms today. So we've actually got to focus on making sure that those teachers who are in our classrooms as of now, have the opportunity to improve their skills and to upskill.
