bloodyteenagers Thank you so much for your time and helpful advice.
I'm actually in the process of filling in an application this evening! And it will be followed by more...
Didn't realise that you don't necessarily need a TA qualification to apply, and in fact looking on the internet I've found a few posts that are 'possibles' - the hours range from 12.5hrs to 20hrs to 37hrs per wk - Grades 3 and 4. They all sound fab.
Job descriptions themselves range from 1:1 help with individual nursery age children, to high school, supporting the SEN services. The 37hrs posts might be a bit much as a starting point, but actually the person spec almost describes me.
The only thing is...I was really looking forward to getting on a course and gaining that 'proper' qualification, which would hopefully lead to more choice, but my DP said I would be mad not to at least try applying for the 37hr post, as it's very near, not much travel involved, "and if there is the chance of getting a post with more pay (it's Grade 4) and local, why would you want to do a course?" Also he said that choices are only there if the jobs are there, and such a post may not come around that often...
But even if I'm not successful, there are the less pay, fewer hrs and more travel ones, to try for as well - which would at least allow me time to get on the course, and a few hours a week is better than nothing. I could just keep looking until someone, somewhere takes me haha.
The more I think of it, the more exciting the prospect of becoming a TA feels - like something has finally 'clicked'.
