I think that someone (probably not the FA because I don't trust them - perhaps Sport England?) should offer Football Grades, analogous to music grades.
These would go from Grade 1 through to Grade 8 (amateur grades) and for semi-professional players a Diploma would be offered as well. The exams for these grades would test individual fitness and technical skills, as well as tactical and analytical understanding in theory and in practice (as a group). The exams could be offered at every school (assessed by external examiners who come in once every half year). Just as in music, football grades would provide motivation and a framework for children to practise intelligently when unsupervised.
One advantage of Grades, compared to the current "system" of coaching and playing (which as far as I can tell is not very systematic at all), is that if there are Grades that build upon each other, then there is a clear focus on development of skill and understanding for each individual child, and not even English coaches could avoid it and have their youth pass.
I'm not proposing this for kids at football academies or for the good of the national team - I don't care about that. I just think 1) sport education currently is ridiculously bad and 2) grades would be a lot of fun for the amateur kids.
