This is pretty much exactly how the public education system is structured here in Switzerland. Early years focus primarily on socialization, multilingualism, literacy and basic numeracy. Then as you move through later elementary school to middle and finally through the Matura phase there are rapid accelerations and bifurcations. If you can keep up you continue on the path to ETHZ and other top Unis. If not you move into the trade or technical school or lower Uni tracks. There is a chance to come back but the baseline expectatio. Is that about 20% of students will go straight through the Matura process. If you complete you have basically free access to any university in Switzerland. ETHZ is something like CHF800/semester. But the trade and technical school path is also good IMO. It’s appropriate.

It’s also not a perfect system but much much better than what I grew up with in the US compared to what I’m seeing now with my son here.
