My experience of primary schools in Finland (and I'm talking state primary schools here - lower comprehensive älä-aste) is that the teachers have an excellent level of training. I have taught in several schools in Espoo and I have always been impressed by what I have seen and heard. I think the Primary School teacher training programme here is of a high standard. Also teachers are respected here... unlike in the UK where teaching does not have much status (as in the proverbial: those who can, do, those who can't, teach). I've read some pretty impressive stats about UK teachers: less than 30% of maths teachers have a degree in maths etc etc.. That would not happen here. Getting on to a teacher training programme in Finland is still competitive whereas, in the UK, the government is resorting to all kinds of schemes to get people back in to teaching (lump sum at the end of a PGCE for example).
And just for the record, all my kids (3) are in state schools in Helsinki/Espoo and I reckon 90% of their teachers are native English speakers. In my youngest's primary school ALL the classroom teachers are native English speakers (5 British, 1 African, 1 Asian), my eldest son is in lower secondary (7th grade) and all his main subjects (English, maths, science) are taught by native English speakers (British, American etc). The IB school in Espoo has several non-Finnish teachers who are teaching in High School (lukio), as does the AICE high school in Tapiola.
penelope - Is there a website or somewhere with more information about this "Upkeep" programme?
These are organised by the local education authorities so you need to look on the website of the town where you want to teach. Eg
http://www.helsinki.fi then under education.... find the phone number for the local koulutuskeskus and give them a ring. For general info on education in Finland go to
