RAD's ballet education system is complete from amateur to professional. RAD, as an amateur examination of universal education, has a long history and is spread all over the world. The grading examination is divided into nine grades, namely from grade 0 to grade 8. Level 0 is a preparatory level, and in principle, children over 6 years old are required to study. 1~3 grades are elementary, 4~5 grades are intermediate and 6~8 grades are advanced. A class is about one and a half hours, and the primary class can be shorter. If you take the exam, the 1 level requires you to be over 7 years old, and there is no special provision in the middle; After grade 6, it is required that 1 1 be over one year old, and there is no upper age limit thereafter. This objectively prevents students from training too early, or being eager for quick success and instant benefit, which affects the normal and healthy development of the body. Of course, there is no problem of the healthy development of adults, but there are many people who are eager for quick success and instant benefit. Please consider it carefully and treat it correctly.
