As much as the children are happy with the LA to see-which is nothing.
The things they write are their intellectual property and if they want to share with me or anyone else, then they can, that is their choice, but thus far, they haven't wanted to share with the LA at all.
Had no problems sharing with the FE college when one chose to go there, or with the OU when the other started a course with them.
The choice of how you share information with the LA is yours entirely.
You can just discuss at the meeting, the things you are doing or you can show then work, it is entirely up to you.
You can have the children present or not-up to you.
But then I am assuming you know you don't have to have the meeting at all don't you?
Again, that is up to you.
Some folks have children who love meeting with the LA and showing work, that is great, as it suits their family.
Other choose not to meet with the LA at all, preferring instead to send in a written educational philosophy and report instead.
