How to become a teacher?Watch
The latter is of course best for keeping your options open, but if your sister is really set on becoming a music teacher then it will be of no loss to her to do Education with Music. However if she is studying Education with Music then she may only be able to teach primary school or secondary school, in which case after studying education she may change her mind which type of school she'd like to teach in.
If she is thinking of the course I'm thinking of, she may be able to qualify quicker than taking a PCGE, because with primary school degrees you can get your QTS within three years.
Although I may be wrong in saying this, but there is probably less you can do with a music degree than say a history degree? I would imagine a lot go into teaching if they aren't playing full time?
Anyway, if your sister isn't sure, then she really must not take the Education with Music degree because when she applies for jobs they may see her as not dedicated to anything, and a person who changes her mind too often.
Best universities... well, for music alone I imagine the usual top universities. For education, whether that be primary school or secondary, again the top universities for other subjects.
Teacher training with specialisation in music course at uni, or degree (music) then PGCE? This is for my sister, I think the latter, my sister is going for the former. What's better? Which are the best universities to do the teaching course at?
