I have kids in the Dutch system now. The foreign language element is still demanding. It is possibly to stream up, but it does add a few years on. There definitely seem to be middle class parents engaging tutors etc to try and get kids into higher academic levels, even though the streaming from primary isn't purely based on academic results.
What I find insane is that in the most academic stream they do Ancient Greek and Latin on top of the normal MFLs. People keep telling me how important they are, but I actively don't want my kids to waste time on dead languages. They already leave school with t
Dutch, English, German and/or French (sometime Spanish). Dead European languages seem redundant on top of that! Given that Arabic is the second most spoken language here, that seems more important than Ancient Greek!
The higher academic levels do seem to pile on the homework which is a big adjustment after primary. There's virtually time for nothing else. But then the streaming for less academic children - gifted in other areas - seems so well done. My friend's daughter did cooking at high school, everything about running a restaurant kitchen. If she'd been in a school pushing academics, she'd have felt she was a failure, like at primary. She really thrives in the new environment. She's now at college studying design.
Interestingly the only person I know who is struggling after school went to a fee paying English-language school here, then did international relations at uni (taught in English here) and now seems relatively unemployable. The kids who took more vocational high school and post high school routes are all employed!
No system is perfect, and there are always people who fall between the gaps, but I think the Dutch do a good job of attempting to develop all children in ways that benefit both the children and society.
