In reply to kays: Whilst the SPA syllabus does not explicitly cover 'coaching', elements of basic coaching are included implicitly. After all, when you rig a climb for students it is assumed they you will be in a position to offer some advice (however basic) to them about how to climb it.
As an SPA with MLTA insurance you will have absolutely no problem with delivering 'coaching' provided that the methods that you use are within your remit and you do not cover subjects that are 'technical skills' clearly outside the SPA.
- You can coach using traversing or bouldering, indoors or outside.
- You can coach using top-roping or bottom-roping in any form inside or outside.
- You can coach with your students seconding inside or outside.
What you absolutely cannot do within the terms of your insurance is any 'coaching' that involves a student lead climbing indoors or outside.
Since bouldering is the best medium for coaching movement whether you happen to be an SPA, an MIA or a professional coach like Neil Gresham you are not at any great disadvantage compared to anyone else.
When it comes to defining what technical skills are within remit, that is a far more difficult issue.
