We take the position as have others that school SLP pull-out intervention is unscientific. It does not represent evidence-based practice.
What is left out of recent papers on the subject (e.g., http://www.asha.org/Publications/leader/2012/120117/Service-Delivery-in-Schools–A-National-Survey.htm) is that it is typically illegal.
By using pull-out service delivery for all or most speech language impaired school children SLPs violate the FAPE provisions of IDEA.
The American Speech Language Hearing Association Board of Directors should take a policy stand against any school practice which violates the civil rights of communicatively impaired school children.
