Can you tell me of any good behavior plans for an aggressive child with ts?

Tourette syndrome?: if by 'ts' you mean tourette syndrome, I'd recommend making sure the child has the best possible diet as well as good quality sleep and plenty of it. Also consider a consistent behavior plan such as 123 magic by Thomas Phelan PhD or others. consistency often helps. Might consider iron testing. also make sure child is not having seizures.

ADHD & anxiety: disorders, often OCD-type, usually co-exist with the chronic motor & vocal tics. They must be diagnosed to develop effective medical,therapeutic & educational treatments. A Neurodevelopmental Exam defines deficits in attention, executive functions, & learning. See a Child Psychologist for Parent Behavior Management Training + Cognitive-Behavioral & Social Skills Therapies for a school-age child.
