OK. First, don't notify him until he's six on the FIRST DAY OF SCHOOL. If you're worried about whether he'll be "ready" according to them in case of sending him to middle school, DON'T! By that time, it won't matter. They will go by his age, rather than by how many years you've been reporting.
As far as the forms go, are filling out ACTUAL FORMS sent to you by the school district? If so, DON'T. They ask for lots of BS that isn't required by law, and try to make you jump through hoops that aren't really there. For example, I don't give a grade level. (A secretary got mad at me one year over that, and threatened to not process my paperwork; I informed her that I really didn't care, as SHE would be in violation of the law, and not ME!) I have one page that lists the SUBJECTS I will be teaching. For example, this year under SCIENCE I have listed Astronomy, Oceanography, Human Anatomy, and Earth Science. Under math, I use to go through the Table of Contents and list all the topics, but now I just write "Math 3" or whatever. Really, it's quite vague! Then the next page is my curriculum list, where I mention all my texts. You can reallly "pad" this page if you want; add any reference book you might glance at once or twice, lol! OH! I also add a "disclaimer", that this is a working outline ONLY, and is subject to change. That way, if something isn't working out for me, I feel I'm "covered" if they come back and demand, "WHY DIDN'T YOU TEACH MAGNETS IN 3RD GRADE LIKE YOU SAID?" Or it also explains why I might list a book two years in a row.
Last, you've got a page that basically has your name and address, plus names of the kids you are hs'ing. It staes that I will provide at least 900 hours of instruction, and that I am qualified to do so. (HSLDA's version also has a note saying that the school board cannot release "personally identifiable information" without our written consent. (This means they can't give my name/address to textbook companies or anything!)
Hope this helps! If you want, I can send you an attachment of what I send in as far as the curriculum and book list goes; I just did for a friend who is starting out this year. The other form you can get from HSLDA if you're a member. If not, check out CHEO's site ( www.cheohome.org
I think is the web site.)
I'm in central Ohio, btw. Where are you?
