If your child is exhibiting problems at school, it is important for the parent to set up a conference with school staff. Use the conference time to identify and clarify your child's problem areas. It will also be important to develop a plan with school staff on ways to address these problems. Have you considered alternate educational opportunities with school personnel?
Have you considered obtaining a high school release to allow your child to participate in a G.E.D.? Have you considered the Job Corps as a means to have your child complete their high school education and obtain work skills?
