Well, if they did not attend, you could sue them because you would have a procedural violation of IDEA that you could then point to as a reason that they did not provide FAPE (no administrator at the meeting to see to it that her program was provided.) My guess would be that they got dinged by someone who filed a complaint. IDEA is a procedural statute, in order to have a case in Due Process, you must first prove that they violated the procedure, and then prove that the procedural violation caused the substantive denial of FAPE.
If you feel like you need help, do some reading on www.wrightslaw.com about advocacy, you will find it very helpful. If you feel like something is going to happen at this meeting and you need help, check out the wrightslaw yellow pages and find an advocate, they can attend the meeting with you, and you will not be alone.
If she failed the state assessment, you can request more services, and that is what I would suggest that you do. You have your proof that she did not make progress, and my guess is, they are crossing all the t's and dotting all the i's on your daughter's IEP, espeically if they just got dinged by another complaint. You can do a serach on the MA Department of Education web site and see what your districts record is. Wrightslaw probably has a link too.
If you hold a private evaluation, use this to get her the targeted services that she needs, and if you do not own one, get one. You need it, especially now that you know that the school has been ineffective. You want to be putting the blame squarely where it belongs, on them, not your daughter. She obviously did not get what she should have, or her IEP was not designed to provide her with one year of progress, and either way, they have not provided her a Free and Appropriate Education, so you hold the Ace in the hole at this meeitng, and if you negotiate well, you could get some compensatory services, and more direct internvention for her to be successful.
Let me know if I can give you any more direction, I am an advocate in Ohio.
