I seem to remember in the 'old days' that most swimming qualifications (teaching and life saving) had a 3 year 'sell by' date after which they were lapsed and had to be re-done. This is similar I believe with first aid. When re-done, there would always be some new way of doing things (only slight changes) which apparently would be 'better' than previous methods. The life saving qualification we have at our school now has been changed to a 2 YEAR sell by date. Surely somebody somewhere is making all of this up just to make money. What is the situation elsewhere, particularly for other sports (eg do football coaching qualifications run out, and if so after how long). It just seems a bit silly to me.
