My school are part of the pilot, although I don't know much about it as yet. My HoD has been on a course though and, as I understand it, the heritage module is just one of the options you can pick. I must say I am quite keen to do some medieval at KS4, because we don't have a sixth form and so, up to now, I have only taught it to year 7. I will post again when I know more of how it is going to work.
