I was a 1:1 TA, and now a class TA.
I'll add that I spend an exceptional amount of time acting as an unofficial 1:1 to help one child in the class (awaiting diagnosis). If I didn't do that the rest of the class would be disrupted constantly and the child in question would learn nothing too.
It is a steep learning curve being a TA. You need to know what motivates all the very different children in your class, be able to take over at the drop of a hat, mark work, give feedback, work with small groups etc. I do all that then am a dinner lady too, so a 15 minute break then back to it. It helps top the wage up.
Most of my TA colleagues are very experienced, and been doing to job for decades. Anyone younger or without experience leaves very quickly because the money isn't great. A few are ex teachers.
Without exception the only reason they can continue is because they have other income streams or due to age they no longer have mortgages to pay. We also are struggling to recruit.
I heard the CEO of the trust moaning about the cost of living... And I bit my tongue. The teachers however are lovely.
I love working with children, but this will be my last year, I can't afford it any longer. I could earn more at Tesco, but something different I think.
