We'd like to advocate for a grade skip for DS5. Teacher recommends for, principal recommends against - but honestly we haven't all gotten together to talk about it more seriously. After seeing it mentioned several times here, I'd like to see what the Iowa scale would recommend. However, neither the school nor local libraries have the manual. I was thinking about ordering it from Amazon, but saw a comment about forms not being included.

Do I need to have the forms if I have a manual? Or conversely, do I need the manual if I have a form?

Manual = $50 on Amazon. Forms = $140 for 10 from Great Potential Press.
