Could refusing to work independtly be a LD sign?

Hi all, I am new here. My son is 8 and has a lot of behavior problems. I have continually thought he might have some learning problems but because of his behaviors and how he tested 2 years ago, the school doesn't think so. They are getting ready to retest him. Thank goodness! But, his teacher is continually telling me that he refuses to work independently. I think this has something to do with a learning disability. Has anyone else ever heard of this? We are also having him tested for auditory processing problems. I couldn't find that on this site. Is there an area for that? Thanks in advance to all!
