you will need to check with the college but i am under the impression you have to have icsf but there are colleges that want to start floristry classes and ask for just experience and you can go and do a teacher training corse through them and that way it doesn't cost you anything i did it that way but i couldn't do nvq till i finished the training but remember my ex boss (retired now) was a college asser and she was qualified to ndsf so you may have to do that one its usally a fresher part-time course through a college then the exam is only done twice a year in a couple of places in the uk its an extermley hard exam as for the theory but practical side shouldn't be a problem good luck.
