The ability to express oneself through written language is a critically important skill for long-term educational, emotional, and social success. However, despite the importance of writing, English Learner students continue to perform at or below basic levels which warrants additional efforts to identify specific areas of weakness that impact writing quality. To that end, this study aims to describe the effect of verb accuracy on writing quality ratings of 5th-grade written expository samples. This study examines the responses of 243 students in the 5th grade who differed in English proficiency. The sample included 112 English Learners and 131 English-proficient students. Verb error patterns in written samples by English Learner students are described and compared to the patterns of their monolingual English-proficient peers. Group differences were examined in verb accuracy, types of verb errors, and overall grammaticality. A regression analysis was used to examine verb accuracy as a predictor of writing quality. Findings showed that English Learner students demonstrated more verb errors than their English-speaking peers and the total number of verb errors was a significant predictor of writing quality ratings.
