Actually pirouettes from 5th are first introduced in Grade 5 and before that an exercise for quarter turn pirouettes is introduced in Grade 4.
I do think that you are missing the point with RAD. The teacher is not supposed to teach just the exam syllabi, but to prepare the children slowly with introductory exercises until they are ready for the finished.....
What is important to realise is that the RAD system never stops evolving and every dozen or so years they completely rethink their exam syllabi. A lot of people remember the old style RAD, which was very pedantic and stiff, with every move set down exactly. They dismiss the system based on what they remember and have no idea how much it has changed since that period. A syllabus is only a piece of paper and a guide line to what is considered appropriate at each level. The teacher has to bring it to life and any teacher worth his or her salt is going to "play" with the syllabus in order to do just that.
And now with the new grades 1-3, spotting and turning actions are introduced right from grade 1! There is a truly throughout progression throughout all the graded and vocational graded systems. It is designed to prepare students to be dancers, the syllabus books are not a training system.
I must agree with Hamorah, I think RAD is stuck in a lot of people's mind as stuffy and old fashioned and un-flexible, but the truth is it is not. The amount of preparation, thinking, planning and development that goes into the RAD syllabus is phenomenal, and it gives such a fantastic framework for teachers to work with, but it is a framework, and every good teacher teaches the students infront of them with a goal in mind and is adaptable.
And Swantobe, just a little note, you would not be able to promote yourself as an RAD teacher even though you have been trained in it without becoming an RAD Registered Teacher. You can get in trouble for that ;)
