I agree! I am one these days :) Just started a HLTA role now, after working as a Level 3 TA beforehand. Was previously a teacher but working as a TA whilst DD is younger for the flexibility. I can afford to do it as my DH is on a good salary and we all benefit from my flexibility with hours.
I love my work but the pay is not great, especially considering the amount of work I do outside of my contracted hours both in school and at home.
I do a wide range of things in my role.
In lessons I support children in small groups or on one-to-one tasks depending on what is going on. It might be doing small group phonics for those who find it harder, may be some dyslexic type activities, a guided read, taking a group outside for extension work, one to one IEP work or just general class support. I will also create new role play areas in the classroom - just made a big Olympic Village with the London skyline, various sports taking place on the other side, etc. I will do circle time or stories whilst the teacher is engaged elsewhere. I will cover for an hour or even a day, leading the class if the teacher is ill or is on PPA.
As a HLTA I will be covering other class teacher's PPA time too.
Before school I run a 3 morning wide awake club for learning support - doing additional phonics work, story writing and reading.
I sort out and deliver intervention programmes - some are pre established, others I create myself.
I also spend a lot of time making resources to use in class - worksheets, display, activities.
I attend meetings with other support agencies, I do pupil progress meetings with the class teacher and the head, i meet with parents...
It's a big role and it is low paid for what is involved imo.
But it is also immensely rewarding. And great fun too !
