Teachers notes are something to be continually refined and added to/ adjusted, and this only represents a basic framework.  Adding personal experiences and new information/ learning is crucial to staying engaged and up to date with the dynamic and evolving world of Permaculture design.    It is worth noting that I currently teach international courses and may change this structure considerably if teaching to students from the same area, (e.g. Within the U.K). The intention is to ease the transition for new teachers by offering a structure and plans for a full 72 hr course as specified by Bill Mollison, where all climes are studied.  This is a basic outline to help guide and orientate only, and several years of practical/ professional experience is recommended before teaching a full PDC.  It is the experience and stories that bring the teaching to life and students respond very differently to the natural passing of knowledge as opposed to text- book accurate but unlearned information.
