Sweetie, they don't HAVE to give you an option of waiting. You already possess this option. You say, "I will take this home and go over it and will return it with changes or my signature. If they say you must sign now, ask why? Legally you CANNOT be forced to sign. They are pressuring you and they have no legal leg to stand on. Ask what will happen if you do NOT sign? They cannot suspend anything and cannot make you stay late for detention. you can even tell them you need to go over it with your spouse who had to be at a meeting. If they push you, tell them that the legal advice you have received is to not sign until you have gone over it as a family and if this is a problem you will contact your attorney and have him contact them.
They do NOT want you to get an attorney involved. Cause they KNOW they can't force you to agree or sign but they want you to THINK they can. Just like they want you to think that whatever they have offered is all that they CAN offer.
If you have already signed, no sweat. YOU are a member of the IEP team just like each of them are. YOU can call a new IEP meeting at ANY TIME. That means if they pressured you to sign the documents and you have problems with it and/or questions, you can call a new meeting the next day. Usually you can just reconvene and discuss new ideas/info, but not all districts are cooperative or even follow the law.
Do you have an advocate? If not, contact your state dept of education and ask for one - you will get one for free. If you and the school cannot come to an agreement on an iep or it is a combative environment, you can get a facilitator to help with the IEP meeting. Here is info on IEP facilitators in OH - it has a number for the Ohio Coalition for the Education of Children with Disabilities in addition to other info about facilitation and mediation of IEPs. You have to click on the top result on this page to get to the flyer with the info:

If they haven't already evaluated him for speech and for audiology, ask if you actually have to write another letter asking for it, the way you did to start the IEP process. If your letter includes something like complete testing for learning disabilities, etc... then it should be included. I believeit is if you used the form letter in the archives.
Just remember the squeaky wheel gets the grease - if you don't get answers send another email and make another call as often as possible. Even every day if theya re not returning calls.
You can also ask for a second opinion if you do not agree with what their expert says (there is a way that they have to pay for this - check the sp ed forum archives or ask over there), but a private assessment may be a better route if you have insurance that will cover it - often evaluations paid by schools look only at what impacts education which is NOT as broad as we might think. A private evaluation covers everything if you want it to.
