Also, Finnish schools are entirely unionized. http://en.wikipedia.org/wiki/Education_in_finland Ctrl-F "union"
One of them suggested that tenure is very easy to get. In the article you posted, "tenure" appears exactly twice, neither time doing anything to dispel that notion. Furthermore, the byzantine and kafkaesque "due process" to eliminate bad teachers has been in the news quite a bit the last few years; I had heard of the NYC Rubber Room long before I saw Waiting For Superman.
Perhaps instead of downvoting my comment and appealing to a political agenda -- I have none, and ironically, most of my family are teachers -- it would be more instructive to discuss the actual issues at hand.
The kafkaesque dismissal process you allude to is the same in most union jobs. 1: written warning, 2: written warning with training, 3: teacher review board. That's it. The administrator knows this and the teachers know this so I don't see how it is kafkaesque in the slightest. The only way to shortcut that is if the teacher did something illegal like sleep with the students or possess child porn.
I also read the piece on the Rubber Room and the reason why the teachers were there was because the administrators were too lazy to actually start the dismissal process. From the same NYT article I read that some teachers should have been fired but hadn't and others shouldn't be there at all but butted heads with the administrators. They were put there because there was a procedure in place but no one wanted to follow it.
You work at a large enough company you'll get an employee manual on ways you can be fired and the procedure in place to do so. That is what wasn't happening in the Rubber Room case.
My personal views are closer to "Waiting for Superman" than Ravitch's, but I (like many ed-reformers) am a lefty. Views on education issues don't split cleanly along party lines.
My take on Ravitch's NYBooks piece is here (the tl;dr version is that her criticisms of the charter school movement as "an attack on public education" are way overblown): http://tumblr.2arrs2ells.com/post/1586044918/myth-of-charter...
Maybe it's more controlled in Finland who can end up as a full-time teacher. Teaching is still pretty popular career choice (esp. for women) and not everybody who wants to be a teacher gets into university to study for a degree. What is the situation in US, is it popular choice anymore?
"You can't have good schools without good teachers"
They fail to mention unionization rates in Finnish schools, though.
As others have mentioned, that is seen as a solution (and one that the US is acting on), however MANY disagree heavily that that is the core issue, as do I. I hope no one is offended by this comparison, but I believe it can be compared to the issue with the massive amount of people in prison in US problem -- can there really be that many bad people, or is the issue something else? I'm 100% convinced it's something else, specifically that (in a lot of cases) the system itself causes the behaviors by motivating/incentivizing it.
So you're looking at 200-300 school districts in Finland and 12,000-15,000 in the US. Standards for everything from bussing to curriculum vary dramatically by state or even by district.
I'd attribute the variation in quality to scale, too much money and poor governance in the US.
