Check out the college to be sure they are servicing the students with the program they advertise. Be sure there are counselors who understand ADD and learning disabilities. Talk to students on the campus about the program. Be sure your adolescent has the proper treatment including medication and counseling. Remember, drinking and medication do not mix.
Structure is imperative.
In the beginning, the program must be structured like a high school program where consistent guidance and support services are provided. Attendance must be monitored and immediate consequences should be enforced for infraction of the rules. Feeling overwhelmed is feeling doomed. Start with fewer courses and less demands. Small successes in the beginning will give your child the confidence to tackle more difficult work.
