 Patients with ASD and ADHD will be recruited for the study from school systems. Half will receive UOT and half will receive CBM. Researchers will recruit interested Title 1 schools that serve very different and diverse populations. Recruitment will occur in several stages. Specifically, school districts will invite individual schools to participate in the trial that have a sufficient number of qualifying children. Interested schools will then contact families and provide information about the study. Interested families will initiate contact with study staff, and individual schools will be entered into the study if they have three or more patients whose families contact study staff. Children will then be scheduled for cognitivediagnostic evaluation. Recruitment will continue until the target enrollment is reached, and all remaining interested families from enrolled schools are included. Subjects with appropriate assent and consent will be evaluated for eligibility and their school will be randomly assigned to treatment condition.
