One of the most significant differences of the Finnish school system compared to other countries' is that basically we don't do national tests at all and we don't do school rankings. Except for the media! They do. Every single year.
Last week Finnish national broadcasting company Mtv3 published their annual upper secondary school rankings. Once again some succeeded and and some didn't. Why? Was it because of the bad teaching?
Personally I don't believe in these kind of rankings. It's pretty easy to be on top if you get the best students in. But what if you live in the area where you can't choose the students. You have to take what you get.
I would prefer the rankings that would take in to account the level the students get in to the school. Personally I'm much more concerned about the schools who get good students in but produce only average graduates. What do they do wrong?
