Thank you for all the information. It sounds a very interesting career, and I would like to apply. I have been to an open day, and have checked with the admission's officer, and I have the right qualifications already. Of course, that doesn't mean I will be offered a place!
One problem is that I work full time and don't see how I can volunteer or observe a SALT at work. It's not easy for me to get time off work. I think if I was able to volunteer or observe it would help my application.
The other problem is that the course is a long way away - about 45 miles away, and the traffic would be awful. I would be driving into a large city in rush hour, so I think the journey would take about 2 hours each way.
However, if I did do it, and got a job, my starting salary would be a lot more than I'm on now, and my work would be so much more interesting.
I am a bit wary, as I have already retrained once. I did a post graduate qualification, and after I qualified, things changed, funding was cut, and there are now very few jobs in that area. I really don't want this to happen twice.
