White belt is the lowest ranking belt within Brazilian Jiu-Jitsu. It is the rank held by any practitioner new to the art and does not require any special prerequisites to obtain. It is the rank immediately preceding the blue belt. Some instructors and other high-level practitioners feel that white belt is the rank where most of the student’s training emphasis should be placed on escaping and defensive positioning, as it can be argued that a white belt will do much of his or her fighting from inferior positions (especially when training with higher belts).
While this may be largely true, and forms a solid training base for belts to come, most academies will require a prospective blue belt to show a well-rounded skill-set, with a knowledge of not only survival techniques, but basic offensive moves, such as common submissions and guard passes
