Do any states have norms or guidelines for what information is reviewed at a meeting to determine make-up/comp-ed services?

A few families and attorneys have raised concerns about meetings to determine make-up services or comp ed. They believe those discussions do not include a comprehensive enough review of information to properly determine whether and how much of those services are needed, so were wondering if any states have norms or guidelines for what information is reviewed at a meeting to determine make-up/comp-ed services. One parent attorney told us there are states that will include SEA staff in these meetings. If any of you do that, can you please tell me more about that process, who participates, and what their role is in the meeting?
