Hi Im in the cities too. PACER is a great option. Their website alone offers much support.
A challenge in mid. School thru high-school is that if the student doesn't need a constant 1:1 and is mostly in general ed, they get lost in the shuffle. The kids frequently are not organized enough to turn work in even if they do complete it.
The gen ed teachers are hit/miss as to whether they even read the IEP or know what accommodations are to be offered.
I'd include a formal way to document that the info has been presented to each teacher, each semester, so you know that has happened. When I case managed I had a folder with the IEP and a brief summary of big points relevant to general ed along with what accommodations they legally had to provide.
I also listed my email and exchange so they knew who to call if they needed support.
I checked in weekly.
As a parent my friends in this situation (my son is not in any general ed anymore) have found that they must take more initiative for making sure the teacher understands the disability and what methods and accommodations help. Some teachers are clueless but willing others are worthless. Many are fabulous.
Online grading systems sometimes are not used well so find out from each teacher if they keep it up.
This is time when we start to want our kids to begin to self advocate. But not time to put it all on them without being taught how.(don't just say if you ever need more time, you have to ask....start with prompting them maybe even giving them the exact wording)....make it clear who is teaching those kinds of skills and how. Make them into goals if needed (rather than accommodations)
Same for who helps with organization of lockers, notebooks and folders, planners, turning things in, etc. If its a problem, don't say he will have support in the accommodation area, make it a goal with objectives. Then someone must be responsible for training and data keeping on it.
If you share his challenges we can throw more ideas out.
Welcome. Feel free to pm me.
