Evidence-based pathways to intervention for children with language disorders.

SLTs have a contribution to make at all tiers, but where prioritization for clinical services is a necessity, we need to establish the relative benefits and cost-effectiveness at each tier. Good evidence exists for SLTs delivering direct individualized intervention and we should ensure that this is available to children with pervasive and/or complex language disorders. In cases where service models are being provided which lack evidence, we strongly recommend that SLTs investigate the effectiveness of their approaches.
