What would you want from a TA?

[Buglife]

I work with families with pre schoolers, have done for 10 years. I'm applying for an EYFS TA position at my local primary school, 5 mornings a week. I have some amount of experience in doing some early years literacy projects with the NCB and planning small literacy events but nothing with me working directly with children without their parents being present. I want to do a part time degree next year in Childhood and Youth studies. What would you want a good TA to do/be like? What do your TA's do in the classroom? I'm a bit worried about disciplining children etc, how would I go about it?! My DC is not school age yet so whilst I visit primary schools in a work capacity and have worked with teachers I'm not massively familiar with teaching these days, beyond reading the EYFS curriculum. Thanks!

1 - to be proactive and offer to help (some I have had sit and join in like a lesson - even putting their hands up to answer a question; some sit at the side not interacting; some only do things when I have specifically asked)
2 - to not talk when I ask the class to listen (some continue to explain something and teachers need there to be silence sometimes)
3 - to help students equally (some sit with the well behaved ones only)

^^ this! I have a signal with my TAs that if I ask for quiet verbally they can carry on, if I clap it's everyone.

Address bad behaviour (as an adult in school it's important that you don't ignore it), but do it quietly. I've had TAs interrupt me to loudly tell a child to sit still/whatever, or loudly SHHHing when I'm still in the middle of my countdown for quiet.
