This study analyzed the persuasive essays of high school juniors and seniors to determine the specific rhetorical and linguistic features that contributed to raters' holistic judgments about the overall quality of the essays. Essays written by a random sample of an ethnically, socially, and economically diverse population of high school writers were analyzed using an array of rhetorical and linguistic measures: overall quality, use of a five-paragraph structure, coherence, three types of persuasive appeals, and sentence-level errors. The relationships between the variables and the holistic scores were examined using a correlation analysis. A forward stepwise regression analysis was also used to estimate the amount of variance contributed by each variable. Results indicate that use of logical appeals, five-paragraph structure, coherence, and number of words were strongly correlated with the overall quality ratings.
