Education and Adoption Bill

If this physics teacher who has deep subject knowledge is taking a class which misbehaves, and he or she cannot control that class even though they have that deep-seated knowledge, does that not suggest that an understanding of behaviour management is important? Or, if there is a child protection issue among those young people which perhaps goes unnoticed by this teacher with deep subject knowledge, does that not suggest that they, too, need some qualification or training in this area?
