What is the title of a volunteer parent helper at school?

[HereBeHubbubs]

Just a quick poll. I'd like to know what I can call myself on my CV as I volunteer in junior school as a reading group helper some mornings. I

I'm in the hall which is split into several reading groups, 'staffed' by one teacher and parent volunteers. I'm in charge of a small group of about 7 children.

Hopefully it might be useful to add to my CV.

What do you think I should word the title as, just 'parent helper' ?

Thankyou

Volunteer parent helper sounds about right.
Then say what you actually do.

Volunteer parent helper.

Then if you've got space you could add that you hear children read.

'Classroom helper' if you prefer.
