What you have so far sounds great.
As the questions they have will always be the same old ones, I would include
the fact that LAs may make informal enquiries if they have reason to believe an education is not taking place.
They don't have to.
There is no duty to visit/monitor.
We don't have to have home visits.
The choice of the way in which information is supplied to the LA is always the parents.
The LA don't have to see the children
Home education is not a welfare issue.
The LA don't have the right to demand to see examples of work.
We don't have to follow the NC/take SATs/GCSEs but can do if we want to.
You don't have to do 11 years of schooling to do GCSEs.
You don't have to have GCSEs to do A levels.
You don't have to have A levels to get to University.
Home Educated children are very well socialised.
There is a whole supportive community out there, that most people don't know about.
best description I have seen, is it is like Alice going through the looking glass and finding a whole world she knew nothing about.
There are home education meetings held all over the country, for social gatherings, workshops and visits. Camps and gatherings are held all over the country through the summer months.
Home educated young people, go to college, get jobs, go to University.
I'd also have a hand out ready with the email addy of HE-UK and the email address and phone helpline of EO in case someone asks for them for more information.
