Thanks everyone!! Sorry it took awhile for me to get back here. Yes, the school evaluated him and he is doing too well to qualify for IEP. I did speak with the counselor and she did think he would qualify for a 504 plan. We are going to look for ways to support him. He has been working very hard and I see improvement along the way.

OT did conclude the SPD diagnosis, but it correlated with his pediatricians thoughts. He was diagnosed as low tone as a small child. We have implemented so many things along the way and the progress has been substantial. His teacher thinks he has a very high IQ and grasps and discusses concepts beyond his years. I hope the 504 plan will give him the support he needs!

Thanks again everyone. You thoughts and resources are very appreciated.

Thank you for the idea about visual processing! I will look into it.
