First Author Writing Measures
First Author™ Writing Measures are a comprehensive group of measurement tools for beginning student writers. The five measures (the Developmental Writing Scale, text type diversity, topic diversity, total intelligible word, and unique words) monitor writing development in the earliest stages of writing and can be used over time to measure progress. First Author Writing Measures are appropriate for use with elementary and secondary students with complex communication needs, including those who use AAC.
