Yan, Xun Avci, Arzu 2020-10-07T22:44:39Z 2020-10-07T22:44:39Z 2022-10-07T22:44:53Z 2020-07-16 2020-08 This study was an examination of the predictive value of complexity, accuracy and fluency (CAF) across proficiency levels and profiles in second language writing. 150 ESL essays of international students registered at a North American university were analyzed using various CAF measures. Descriptive statistics and one-way ANOVA results indicate that fluency is the strongest indicator of proficiency. Accuracy is also found to distinguish across proficiency levels. Length-based complexity measures are found to better predict proficiency while subordination is found to be a comparatively weak indicator. For lexical complexity, number of different words could better distinguish writers across proficiency levels. When results are analyzed for language profiles, it is found that syntactic complexity and accuracy better distinguish across profiles.
