Hi,
Sometimes a public school is better equipped to follow through an IEP, which the kid needs to provide him with resources and accomodations to help him with his difficulties. A label is needed to get help, but help means going beyond the label.
I suggest you help your friend write a letter to the social worker , a type of parent report , her concerns for her son, her opinion , assessment of his difficulties , using examples etc , the need for an evaluation and an IEP for school and guidance for other caregivers.
I would use this caregivers handout and others resources maybe Chandler papers to help you describe the child's issues
since the parents are seperated, the child's voice is pretty important. I think some one has to reach out to him and help him become part of the solution to find help.
Without help the kid will never aquire the emotional intelligence to cope with life.
She needs her husband's cooperation and of course her son's.
