Does the student at least have a 504? To give her some accommodations for her attention issues, anxiety, and depression? You might want to pursue this path WHILE you are fighting the IEP battle, just to get something in place. Or is the school saying she doesn't have a disability because she doesn't have a diagnosis of ADHD or anxiety? If so, request an IEE so that (hopefully) you can get some diagnoses on the record and they have to provide a 504. Then when the IEP is finally implemented, the accommodations can switch over to that document. They can DEFINITELY do something to support her with turning in homework.
It is untrue that the school doesn't have to address the school avoidance issue. They have to look for the cause of the school avoidance and see what supports can be put in place to help the situation. Otherwise, her missing so much school results in them not providing FAPE. Request a Functional Behavioral Assessment (FBA). If they refuse, ask for an IEE.
What does their "reading at grade level" mean? Did they look at accuracy, fluency, AND comprehension? She may be able to read, but if she is not reading fast enough and/or not understanding/retaining what she is reading, that might be why she is "reluctant" to read. If the school eval didn't dig deep enough, again, ask for an IEE.
Unfortunately, is sounds like your state's DOE will be no help, and I'm sure the school district knows that. Any legal counsel who says getting parent input is "inefficient" is ignorant regarding the IDEA.
