You may wish to consider the following, I feel that it makes clear the distinction between qualification and licensing, it is a précis of an extract from an article that appeared on pages 9-10 in the Autumn 2009 edition of The Rifleman:
"Qualified, Licensed, Appointed – What’s the Difference?
A qualification generally means that at some point you had the necessary knowledge skills and behaviours which were benchmarked to a certain standard.
Possession of a coaching license indicates that you not only fulfil the above criteria but that the knowledge is current, there is evidence that the skills have been used and the behaviour is in line with current best practice. It also ensures that the other elements are in place and monitored – such as CRB checks, insurance and safety ensured by being a current RCO, etc.
The license means that not only have you been trained to a certain standard but the currency of that knowledge is ensured along with the underpinning factors. Licensing means that a certain standard is ensured and backed by the National Governing Body.
Appointment is not in the gift of the NGB. The NSRA does not appoint club, county or regional coaches (or instructors), that is at the discretion of those bodies to choose the person most suitable for the post. Clearly it makes sense to appoint people who are qualified and whose license is current for the quality assurance reasons stated above.
Ideally a coach can operate best if they are qualified to the correct standard, currently licensed and then appointed by an organisation to carry out their duties. A person receiving coaching can then be sure that they have a trained, currently competent coach whose activities are endorsed and supported by local and national structures."
To me the implications are quite clear. If you operate as a qualified but unlicensed coach (or instructor) and something goes awry; accident, incident, injury, child protection issue etc.; then you and the body that appointed you might be in a very exposed position.
