I’m Trying To Get An Idea On How To Set Up Goals For Behavier And Social And Also Learning Disability, The Iep

If your son is 16 his goals need to focus on the skills he will absolutely need in the real world. He needs to be able to get along, be independent, be accepted, hopefully be self-supporting, etc.
You haven’t really told me enough about your son for me to suggest specific goals as that depends on his current skill level. Think about what he can do now in various areas, and what would be the next skill in that area. That’s one way to look at it.
If your son has behavioral support at school that obviously means that his behavior needs to be addressed. What are the two or three main things he does right now that are big problems. What are the tow or three things about him that you are most worried about? Identify those and begin to think of a plan to improve things in that area.
You should not have to do all of this yourself. His teacher should help with thinking of the goals if you can come up with the areas that you think he most needs to work on.
I will check back in case you add more details. Good luck to you and your son.

I’d talk it over with the special education teacher.

You didn’t leave much time to respond. First, your meeting is just part of an ongoing process. You don’t have to be totally prepared. You are not going to drop dead.
Hopefully, the School Psychologist can help you define the behavior that concerns you in a manner that lends itself to measurement and intervention. He/she might have some ideas also based on their classroom/school observations of your son. If he/she hasn’t already addressed your concerns, asked for their attendance at the IEP meeting.
I wouldn’t put to much weight on the responses you find here. It would be an impossible task to asertain specifics without evaluating/knowing your son.
