The main purpose of this study was to examine technical adequacy and classification accuracy of writing measures for universal screening. Despite increasing awareness about the importance of early identification and universal screening in writing, little research has been conducted. Based on previous research, we selected picture-word and sentence copying as alternative universal screening measures. Results showed adequate reliability and validity of both measures. In addition, classification accuracy of the measures was promising as well; picture-word prompt showed more desirable classification accuracy than sentence copying. We discuss limitations of the study and implications for future research and writing practice.
