At the moment you are quite within your rights to choose how to give information about the education you are providing. The Guidelines above make that very clear.
"If they choose not to meet [with the local authority], parents may be asked to provide evidence that they are providing a suitable education. If a local authority asks parents for information they are under no duty to comply although it would be sensible for them to do so. Parents might prefer, for example, to write a report, provide samples of work, have their educational provision endorsed by a third party (such as an independent home tutor) or provide evidence in some other appropriate form."
If the LA says anything to suggest that the situation has changed, and I have heard of LAs who are saying this, remind them that the DCFS is consulting on this area at the moment, so how can it have already changed?
