Following the completion of a computerized database search seven articles meeting the inclusion criteria were included for analysis. Study designs include: nonrandomized control trials (between groups and mixed), within group (repeated measures), and expert opinion articles.  \nOverall, research does not support the use of nonverbal intelligence scores as an exclusionary criterion used to categorize children as having specific language impairment. A discussion of clinical recommendations is included.  \nIntroduction  \nSpecific Language Impairment (SLI) is a significant impairment in one’s ability to use language (either expressive or receptive) that occurs in the absence of hearing impairment, mental retardation, motor disorder, socioemotional dysfunction, and/or neurological damage (Friel-Patti, 1999 ; Plante, 1998) .  \nChildren with SLI represent a unique clinical group that has been difficult to identify. One of the first criteria aimed at defining this group was to rule out those whose language difficulties were due to general cognitive impairment (Plante, 1998) . This criterion was operationalized as a score on a nonverbal test of intelligence within one standard deviation of the standardized mean (>85; Stark & Tallal, 1981) .  \nIn recent years, variations and adaptations of this method have been used by clinicians and researchers in the field of speech-language pathology to identify children with SLI, as a result much heterogeneity exists in the way that nonverbal IQ scores are used to identify children with SLI; such that there currently is not one universally accepted method for identifying children with SLI (Plante, 1998; Krassowski & Plante, 1997) . Current research attention has focused on the way that nonverbal intelligence is used to identify children with SLI (Rice, 2004) .  \nStudies have demonstrated that SLI is an enduring disorder effecting children during the school years and continuing throughout the lifespan (Friel-Patti, 1999) . This then has far reaching implications on a person’s quality of life including educational and occupational success. Ensuring that accurate criteria are established and used when labeling children with SLI is important since eligibility for services is determined based on  \ndiagnosis. Therefore, determining the appropriateness of using nonverbal intelligence scores as a criterion for determining the presence or absence of a language impairment is of critical importance for ensuring that children with language impairment are provided with the treatment they need.  \nObjectives  \nThe primary objective of this paper is to review and critically evaluate the existing literature concerning the use of nonverbal intelligence scores as a diagnostic criterion for SLI in children. A secondary objective is to discuss the clinical implications of these findings as they relate to the field of speech-language pathology and to propose recommendations for speech-language pathologists who are working with children with SLI. This information is also relevant to researchers who use nonverbal intelligence scores as a criterion for grouping participants into experimental groups.  \nMethods  \nSearch Strategy  \nComputerized databases were searched including CINAHL and PsychInfo using the following search parameters: (cognitive referencing) AND (specific language impairment) OR (language disorder); (specific  \nlanguage impairment) OR (language disorder) AND (nonverbal intelligence) OR (nonverbal IQ) OR (performance ","cbCaicGJrZcZHJKs","https://ap.wps.com/l/cbCaicGJrZcZHJKs","pdf",159250,"English","# Introduction\n# Objectives\n# Methods\n## Search Strategy\n## Selection Criteria\n## Data Collection\n# Results\n## Nonrandomized Clinical Trial: Between Groups","[{\"question\":\"What is the main research question of the critical review?\",\"answer\":\"The review evaluates the validity of using nonverbal intelligence scores as an exclusionary criterion when identifying children with specific language impairment.\"},{\"question\":\"How were studies selected for inclusion?\",\"answer\":\"The paper uses computerized searches in CINAHL and PsychInfo and also searches reference lists.
