Being a peripatetic music teacher is such a complex job, but an amazingly rewarding one.
I began teaching in my second year of a music degree, and have never looked back.
I started off with private pupils, but am now attached to two schools.
Teaching qualifications are useful, but not essential. I have a BA (hons) and 7 years of experience, but no actual teaching certificate.
One of the most important factors is whether you as a person can cope with the demands of being a peri.
Having a performing diploma or a degree is a good starting point, though not essential.
Good performers don't always make good teachers, but to be a good teacher, you
can't be a bad performer.
You are required to be so much as a peri - teacher, counsellor, accountant, administrator, timetabler - and it's a demanding job.
It's more or less inevitable that you will have to deal with difficult parents at some stage too, which is never something you can prepare for.
When I started out, there was no support network for peris, but now we have a much larger network where we can share ideas, which is great.
So........in summary - qualifications aren't needed, but patience to get your teaching practice off the ground is a must!
