They don't call it "ABA", in Romania. Too inward looking a culture. They'd die before calling it ABA but it uses all the same principles. You are right too about the lack of legal framework, but then the all effort has been put into getting their sleeves rolled up and working with the kids rather than talking shop.
Their SN system just isn't saturated with trendy buzzwords and their whole approach is incredibly down to earth and about calling a spade a spade. There is no money at all for endless "professional meetings" and all the codswallop professionals over here have to wade through. Here people make a living out of being incomprehensible to the lay person through the use of jargon.
I think it translates as "intensive teaching", or "systematic evidence based" but having compared there and here with the help of an ex-MIL who is a primary teacher over there, the variations seem to be as small (or as wide) as you'd find between two different providers over here.
Just as an example lots of people will be familiar with - the very popular "write from the start" handwriting programme we use here is the standard mainstream way that ALL children are taught in Romania as the evidence proves it to be the most effective. (Author = Teodorescu & the clues in the name lol!).
I fully agree about the treatment of the Roma - to say professional & public attitudes are disgusting doesn't begin to cover it! Those awful orphanages are still being refilled with unwanted babies/children daily even though it no longer hits our press too. It's not all sunshine and roses over there, particularly in the current economic climate which has left a lot of E. Europe in a far bigger mess than Greece.
Some of the best professionals DS has come across (including his NHS SALT who deserves national recognition imho) have been from various ethnic minorities. The issue in my area is that the gatekeepers to professional services seem to have been the survivors from Noah's flood that somehow got stranded on their own little hill fort of bigotry and ignorance.
