I trained as secondary (French) teacher, worked for a few years in a London comp, left to have dc, moved around a lot, had loads of kids. Ended up being off work for 14 years 
Fast forward.
2 years ago (now living in Germany) I finally got the chance to return to work. My French ability and confidence long since gone, I took a position as a TA in a private school (primary). I really love my job, but after 2 years feel very much overqualified and under-challenged.
To work here as a teacher you have to get official recognition. I can't get that for secondary as my French is now not good enough, and probably cos I haven't work in secondary for so long. I can't get it for primary because my training is officially for secondary.
So, I'm trapped. I would 100% want to stay in primary. I guess my choices are accepting remaining forever as a TA, or doing the entire PGCE again? Which costs loads, and I would have to do it distance learning, and am already just keeping my head above water working (almost) FT and looking after kids and house). Not sure I can face studying again. Or are there any other options I haven't thought of?
