I am in NOVA. They are required to send you the IEP and findings 2 business days ahead of the meeting so that you can review prior to the meeting. If they did not do this, you can ask for a second meeting because you've had time to think and you want to request changes. This document gives you the best overview of the process and might have ideas for you to talk to them about to improve the process.
