Reading is probably at a 4th or 5th grade level. I forget the exact lexile range.
Our issue is that the gifted program is all handled by the regular ed teacher, so the length of instruction time devoted to differentiation and instruction at a higher level is really not at all equitable for a high achiever vs the general curriculum and the rest of the class. The "year of progress" is being stunted. We've been doing Khan Academy at home, and while it advances knowledge, I know the opportunity to participate in group work for practice and application would be missed if that replaced classroom instruction. We would've subject skipped him had it not been for the school not aligning the two math periods which would now cause specials to be missed if subject accelerated. I'm hoping to find a happy medium of staying in the current grade subject, but receiving actual instruction "length" that's on par with other students (I want our "fair share" of proper on level instruction and practice/application).
