This review of the literature was in investigation of informal measures used to assess syntax in normal-language and language-impaired, school-aged children. From the eighteen studies that were researched in this review of the literature, 86 measures and their variants were reviewed. Data concerning the T-unit, the most widely used measure for determining syntactic maturity was reviewed as well. Any findings uncovered regarding the syntactic skills of normal - language and/or language-impaired, school - aged children were summarized (typically on the basis of ability level, age or grade level, and sex). In addition, the strengths and weaknesses in previous studies of oral syntactic maturity in either normal-language or language - impaired, school- aged children was discussed. This was done by systematically reviewing indicators of study quality.
