Interview with Tony Wagner:
[Finland] began in the 1970s by completely transforming the preparation and selection of future teachers. That was a very important fundamental reform because it enabled them to have a much higher level of professionalism among teachers. Every teacher got a masters degree, and every teacher got the very same high quality level of preparation.You can't have good educational outcomes unless you have good teachers. I find it shocking how many countries are letting the teaching profession fall into disregard. It is the way to an incompetent future work force, and uneducated voters.
So what has happened since is that teaching has become the most highly esteemed profession. Not the highest paid, but the most highly esteemed. Only one out of every 10 people who apply to become teachers will ultimately make it to the classroom. The consequence has been that Finland's performance on international assessments, called PISA, have consistently outranked every other western country
