This document discusses issues related to testing writing ability. It emphasizes the importance of ensuring tests are representative, valid, and reliably scored. Representative tasks should sample all possible content domains. Multiple tasks increase validity by providing more opportunities to demonstrate skills. Scoring should be either holistic, considering overall impression, or analytic, separating different skill aspects. Proper scorer training and calibration are needed to reliably rate performance. The goals are to accurately measure writing as an independent skill while maintaining practicality and meaningfulness.
