I was a secondary MFL teacher for 14 years, and am currently in my 2nd year teaching Spanish from nursery to Y6 in a local primary school. It suits my school very well. If you read the latest Ofsted report "MFL: Achievement and Challenge 2007-2010", you'll see that they recommend the "class teacher teaching the language" model. However, all schools are very individual, and what suits one won't necessarily suit another. I would recommend that, if possible, you attend some CILT courses, and contact your LA PML consultant, before the end of March as he/she may well be redundant after then. The best way to learn about PML is to see it in action - the training zone on www.primarylanguages.org.uk has some excellent videos. Also familiarise yourself with the KS2 framework for MFL. That's really the only specific training I've done.
