Not sure how things work in your jurisdiction, but here the enrichment/acceleration issue would be addressed outside the IEP. I agree with others in recommending that you reschedule the IEP meeting so his teacher can attend. Remember just because the team is recommending reduction of acccomodations doesn't mean that you must agree or sign on the dotted line. If you feel that the team has a reasonable basis for their recommendation, you can still insist on a substantial trial period without formally removing the accomodations. As for the enrichment pull-out, it would be helpful for you to get specific information regarding the content and qualification guidelines/deadlines before advocating. It is possible that this school's program is set up very differently from the former school's program. I don't mean to imply that your DS wouldn't qualify, only that knowledge is power if you want to prevail.
