It’s something you need to explore. Primary is tough, mentally and physically in some cases. Get as much volunteer experience as possible in a range of primary, difference year groups etc. Easier now restrictions are eased. Talk to staff, look at local jobs and note which schools come up again and again. You will need lots of work experience to get accepted on a PGCE or you did when I did a few years back.
You need to be Teflon coated as you will be likely abused by staff and parents/carers. You need to take it on the chin. We have had fathers say they are coming to ‘sort out’ staff for commenting on how lovely a child’s lunch was (I kid you not.) You need to be performing the role of teacher and not react.
I came from a corporate background with silly hours but asides from one job where the director did run it like a school (told off entire dept lack of effort at fancy dress party we had to pay for was one example of many) I have never been so micromanaged. Core lessons, like phonics, are effectively scripted and are so dull.
Primary is challenging as there is likely to be a high percentage of need, SEN, LAC, PP and those yet to be recognised children who fly under the radar. There will be neglect which isn’t just down to economics. And you are likely to have one TA if you are lucky.
Then there is the paperwork for all the above needs, data tracking, incident reports etc. Then planning, observations, endless meetings and new strategies (or teaching grandma to suck eggs according to experienced teachers).
But there is the buzz of being with the children, if you have a group of lovely children which most are, then there is no job like it. It is a pity it is so damn hard emotionally.
But if you want to explore it, do it but remember it is a job and walk away if it starts to effect your health.
