50+career change

Hi I'm changing career to teach in a college, never done teaching.
Always working with young people in social care..
I did a degree many moons ago
So do I choose cert ed or PGCE ... I'm poor old brain ..
Any advice

College is a generic term that can be used for Schools and academies or FE colleges, and for you there is a key difference. FE colleges may be able to let you teach before you've got a qualification, based on your professional experience. Schools/academies, whether they call themselves a College or not, probably won't. There are various ways into teaching, they are just a Google away, or on a forum here on TSR.

It's a college that teaches 16+ has great health and social care department.

Then ask them. They will have seen all routes and will advise in your specific context and their need and experience.

I was hoping to get advice on here

You got some - ask the people that are most likely to know the answer contextually!
You wrote a fairly illiterate, uninformative first question in an online forum primarily aimed at people aged about 15-25 about a subject the vast majority will have zero knowledge or experience of. There are only a handful of us on here who have experience of being 50+ and making calculated careers decisions, and as one of them, my advice is that a) you learn to Google and do some of the basic leg-work yourself and b) you ask the expert resources you seem to already be in contact with, because they will have experience of this.
