It's self‐evident that the more complicated a child's presenting problems are, the more critical it is to have the combined expertise of a multidisciplinary team applied to the case. Everyone is aware of how the tremendous expansion of all the sciences in recent decades means that no single individual or discipline can encompass all the knowledge relevant to helping a particular child. Complex developmental and behavioral problems have no single solution; rather, a coordinated multipronged approach best serves such children. What types of expertise are needed, how much professional time is available, who is paid for what service, etc. all must be considered in developing a comprehensive treatment plan. Obviously, collaboration among a team of professionals is the correct approach.
