UKCC (United Kingdom Coaching Certificate) is now the standard for all sports teaching qualifications. The ASA has managed to secure the license to deliver these new qualifications to the exclusion of all other “influential” organisation.
The New Level 1 qualification does not give the candidate the information to allow practice in the workplace to gain the experience to move onto a Level 2 qualification
The New Level 2 qualification only gives candidates the knowledge to teach pupils up to basic stages (ie. ability to swim about 100m)
There appears to be no course that we can determine that teachers swimming mechanics at a level that will allow teachers to improve technique of those who can already swim a bit.
