New member here!  : )  Our 7th grade son has had an IEP since Kindergarten, has multiple challenges our local school district can't handle.  We have an agreement they will agree to placing him there as long as he shows progress?  He has mastered his last 2 IEP goals, loves it there and has made progress in our eyes.  How would any of you define progress?  Thanks in advance.  

Glad to hear that you're happy with the progress! Did your public school define their expectations of "progress" for them to continue to pay for the placement in your agreement? Are there concerns that the school won't be happy with the amount of progress at the private placement? Does someone from the private placement attend IEP meetings with you to help advocate for your child?
