"Legislation will be brought forward to introduce guarantees for pupils and parents to raise educational standards"This refers to the Children, Schools and Families Bill which will "introduce a new home educators' registration system."
A good article on the Badman Review of Home Education, which has been used to justify the new legislation, describes it as "Policy Based Evidence Making."
[Correction: many thanks to those who corrected my impression that the Bill was to be debated in the next few days. I've removed that section of the post. I'll post something more later.]
