What qualifications do I need to be a preschool teacher?

[Mamaalwaysworried]

I want to change career and start teaching preschoolers (3-5 year olds).

What qualifications do I need?

I hold a BA and MSc but in unrelated field (Marketing)

Mama the best place for this question is probably The Staffroom on MN, no idea where it is, but there's heaps of primary school teachers there!

You don't need QTS (Qualified Teacher Status) but you do need qualifications in EYFS. I'd expect EYPS as a minimum.

Do you have a lot of work/volunteering experience?
