Completion of a training course is not an indication of competence. People that say they are mountain leaders after completing a training course are not telling the truth!
Tis is the AIR Training Corps's official line:
From 1 April 2002 leaders of activities in mountain areas must have completed ML assessment. Leaders who have completed ML training but not assessment may be permitted - for a limited time - to lead activities in wi1ld country, provided that they registered with the Wing Adventure Training Officer before April 2002, and were then assessed as being "competent through experience" (CTE) before 1st April 2003
The CTE register is a temporary measure to allow experienced staff to continue running activities for a limited period. i.e. until they complete their assessment or retire from the Corps.
Personally I think it's bizzare that the these new rules have been bought in partly as a result of the
Jonathan Attwell a scout aged 10 fell to his death on Y Lliwedd on an official scouting trip and the scouts still seeem to be doing 'in house assessments and then have only done a training course after that!
