It is best to tell the LA keep everything in writing rather than having phone conversations. There are several reasons for that:
- You have a record of what was said. This avoids misunderstandings and discourages some of the worse LAs from telling fibs.
- It creates a paper trail so if there are future disagreements you have proof of what happened. This is very helpful in the unlikely event it should go to court.
- You have time to think about how to respond. This is especially important if you are new to home ed, don't know the law inside and out and want to take advice.
- You can respond at a time which is convenient to you when you can focus on it and the conversation won't be overheard by a child who might fear being sent back to school. This can be particularly frightening for kids who have had a traumatic time at school. You can shelter them from that by doing it in writing.
Depending exactly what your LA meant by "education plan" and "evidence of work", they appear to be misleading you already about the legal requirements, which is a good reason to keep them at arms' length even if they seem nice.
You do not have to submit future plans and it is inadvisable to do so, because if the plans change the LA may say that you have failed to achieve what you set out to achieve. Any reference you may make to future plans should be hedged all round with provisos, e.g. "we are exploring the possibility of..." "my child has expressed an interest in..." "there is a class available to her..." and say that of course your education will be responsive to her evolving needs and is therefore subject to change.
The LA should not be requesting "evidence". You are not in a court of law. At this stage they should be making informal enquiries, which you may answer by providing information in a format of your choosing. Those who are up on the law recommend submitting a written report. This should be about what you have done and are doing, not about future plans. The report IS your evidence and would be accepted as such in court unless there were strong reason to believe you were lying. So you don't have to submit photos or copies of the child's work, for instance.
On the plus side, six weeks is a reasonable amount of time for you to settle in and have something to tell them. So you have ample time to think about what you want to say and make some notes as you go along of things you want to include.
If you want some help with it, I suggest you join the Facebook group I mentioned, where they have templates to help you write the report and very experienced people who will be happy to look at your draft and ensure the report is up to scratch.
