Graesser, McNamara, and Kulikowich (2011) describe the value of the Coh-Metrix system for providing multilevel analyses of textual difficulty. This comment article discusses the broader usefulness of Coh-Metrix for text researchers in providing information about multiple variables in textual features. Coh-Metrix may encourage researchers to develop a greater variety of texts because it highlights where texts may vary. It also is free and easy to use. Its most useful contribution may be allowing researchers to discern which textual features are most critical to comprehension for different populations at different moments in development.
