In NL the latest news is that underminister (staatssecretaris) Dijksma has
decided to have some research done on electively HEing families in order to
answer the question whether or not regular supervision is useful enough to
change the law for it.

She sent a letter to the Parliament in which the govt acknowledged for the
first time that foreign research on HE showed good results.
For those who read Dutch, here’s her letter:

The problem now is to make a HE law that is acceptable both to us HEors and
to a parliament filled with rather prejudiced opinions when it comes to
education.
