First grade can often be more problematic than kindergarten because there is a lot more seatwork so less fun games and projects and social time. You simply have to accept that even with the most accomodating district, it is still a bureacracy so everything will move very slowly. Make sure that your requests are in writing and reasearch the policies and procedures for your district. Don't rely on IQ scores as that is unlikely to get you far without accompanying acheivement scores or other proof of mastery of specific curriculum.
