Purpose: This study was designed to assess the utility of a tool for automated analysis of rare
vocabulary use in the spoken narratives of a group of school-age children from low-income
communities.
Method: We evaluated personal and fictional narratives from 76 school-age children from lowincome
communities (mean age = 9;3). We analyzed children's use of rare vocabulary in their
narratives, with the goal of evaluating relationships among rare vocabulary use, performance on
standardized language tests, language sample measures, sex, and use of African American
English (AAE).
Results: Use of rare vocabulary in school-age children is robustly correlated with established
language sample measures. Male sex was also significantly associated with more frequent rare
vocabulary use. There was no association between rare vocabulary use and use of AAE.
Discussion: Evaluation of rare vocabulary use in school-age children may be a culturally fair
assessment strategy that aligns well with existing language sample measures.Communication Sciences and Disorder
