We make a distinction between training skills, whether obtained formally or informally, and craft skills.
In training skills we are concerned with the trainer's ability to train, their understanding of how adults learn and their commitment to collaborative learning.
In craft skills we are concerned with their ability to do the task that their training is tackling. Eg: A journalist trains others in journalism (craft skills) using their abilities as a trainer (training skills).

subject matter expert
The concept of a Subject Matter Expert (SME) is well known in training and education.
It is generally recognised that a trainer/educator may be competent to train ie knows the necessary skills and has the ability to deliver training in competent/professional manner. That same trainer may not have the necessary knwoledge in the subject to effectively facilitate learning in the specific field.
A subject matter expert is just that. Jim Fraser of Fraser Associates has suggested that there are additional degrees of expertise and has offered the definitions of "Subject matter resources (SMR's); subject matter experts (SME's) and subject matter masters. Someone could be one of the above in training, in a specialized content area or both. The highest order of our tradecraft isn't in our ability to do it, it is in the ability to teach others to do properly."
