This study targets school-age students with a Speech-Language Impairment and/or a Specific Learning Disability between the ages of 10 and 14 who are receiving services from a Speech-Language Pathologist (SLP) for one or more higher-level language behaviors. It is expected that participants will demonstrate higher levels of fluency with complex sentences compared with pretreatment baseline levels and that treatment effects will be reflected in several modalities and in naturalistic language contexts.
