Where to get the best training
Teachers should have access to properly accredited, fully funded, relevant, academically robust CPD. The best people to provide this are higher-education-based teacher educators. Their work, unlike private operators', is subject to effective quality assurance.
Moreover, these institutions do not run courses for profit. The effectiveness of such courses has been acknowledged by, amongst others, Ofsted.
