Update:

There has been a suprising turnaround! I was prepared to march into the school arguing my points, but the school is now saying that it should be no problem at all for him to do 6th grade math next year smile They are claiming that all the problems with my DD a couple of years ago was because we wanted her to skip 6th grade math (she had all the data to support it according to everyone except the school) and that 6th grade math is "the most crucial year of Saxon math of them all" and not to be missed. LOL! So they feel satisfied that "skipping" 5th grade SAXON math will be okay since he's in 5th grade non-Saxon math. Not that they still don't think their math is superior . . . .

Thanks so much for all your input. You all never cease to keep me sane!

She thought she could, so she did.
