A Level III guide should be able to point out and explain in terms of scientific theory and cultural belief, the features of the natural environment in which s/he is operating, and putting it into broader ecological context.
As a general indication, the knowledge and insight expected at this level is unlikely to be obtained without at least two years of active guiding in the field.  A general distinction between the competence at this level as opposed to lower levels is the ability to explain phenomena by means of valid and well-motivated scientific theories and the concomitant use of appropriate scientific terminology.  The Level 3 guide will need to know all the information contained in the Level 1 and 2 syllabus as well as the information in this level 3 syllabus.
The Level 3 guide is also expected to be able to discuss current conservation and sustainable tourism issues from within the existing socio-political framework of Southern Africa and the broader African continent.
