Also, the Netherlands reintroduced sex segregation in public schools in order to encourage schooling of muslim girls (Bjinse can correct me if I'm wrong).

As far as I know, this hasn't happened. I've never heard about this, although that doesn't mean much. Google and a search through the Dutch newspaper database don't render any hits either. There is always the off-chance it hasn't been big in the news and politicians haven't heard about it, although that'd be doubtful, considering the topic.

Secondly, such policy doesn't make immediate sense to me but when dealing with politicians, that doesn't mean much either. But if I recall the statistics correctly, Muslim girls are doing much better in the Dutch education system than Muslim boys, plus the past years have seen an overall improvement for both sexes - although it's still far from optimal.
