>At what age is Informatics\CS first compulsory 2-4 grades - elective (in some schools) 5-end of school as compulsory for all schools. >when does it stop being compulsory It doesn't. Here in Russia we don't have a system where you can chose your subjects, even in high school (university[1] etc). Instead there is an educational programm to follow. Plus some schools provide elective subjects which you can add to you programm (for example second foreign language). >Are there specialist teachers Yep, there are. Specialized schools (we have general schools and schools with specializations, for example with deeper math&physics, or biology, or languages) might have several CS teachers (for example one who teachers younger kids simple things and general programming and the other one with algorithmic\math\network bias). [1] Obviously in university the programm will differ depending on department you are in and other small things.
