The Shoden (Beginning Transmission) breaks jujitsu down to its core building blocks.  Principles such as kuzushi (off balancing of an opponent), tsukuri ("fitting in"), and kake (execution of the technique) are taught at the Shoden level. The Shoden curriculum is comprised of the Rokkyu, Gokyu and Yonkyu courses.

An excellent description of Shoden, written by Professor Dennis Estes, can be found here: Shoden - Beginning Teachings.

The Chuden (Middle Transmission) brings the basic principles learned in the Shoden together. Among other things the Chuden explores transitions, counters, and introduces the concept of Kiai. The Chuden curiculum is comprised of the Sankyu and Nikyu courses.

The Okuden (Deeper Transmission) is the black belt course and focuses on more advanced techniques and esoteric principles. The Okuden curriculum includes the Ikkyu course.
