Academies Bill [Lords]

That may well be the case generally, but not in this situation. Changing to an academy is a one-off event of some significance in a school's life, so parents would be well aware of it and the school would communicate with them. If the parents were alarmed, I am sure they would make their views known. I know that parents of children in my local area are well attuned to what is happening in their local school, and if they are alarmed by something that is going on, they soon raise it. They can do so directly with their councillors, with their MP or with the school's governors.
