We have 3 major types of high schools in my country.

1) The ones that prepare you for University and a high-level white collar job.

2) The ones that prepare you for a (low level) practical-focused white collar job, high-level blue collar job, or something similar to junior College.

3) The ones that prepare you for a manual labour job.

Unfortunately, in my country, they look very negatively at the last two categories, which causes what we call a "waterfall system". That is, lots of students get pressured by their parents to start in the first type, which they can't handle and then fail their grade or transfer "down" to the other two. That means, changing a lot, and many students therefore lose time, as they could have started in type 2 or 3 and have excelled there from the start.
