What I did when I was presented with a weak IEP is I re-wrote the IEP. It took some time but I practically wrote my son's entire IEP... I have found you can not count on the school, they will put forth the bare minimum. The school gave me push back but I had the mindset that I had the final say - this was my child and the school works for me sort-of-thing. I also had advice from here and I knew what I was including was not unreasonable.
