Eligible participants will then be randomly assigned to receive the CLAS Program, parent-focused training (PFT), or community referrals. The CLAS Program will involve a half-hour orientation and up to five half-hour weekly meetings with the child's teacher, therapist, and parent over 11 to 12 weeks. The program will also involve ten 1.5-hour group sessions for parents, with separate group sessions for children at the same time, and up to five individual family sessions led by a therapist. Teachers will participate in a school-home note system for maintaining and rewarding child behavior; parents will be taught strategies for giving commands, using rewards and consequences, and establishing routines and organizational schemes; and children will be taught social interaction skills, homework skills, and organizational skills.
