A Mandarin Chinese Function Catalog and Instructor Rolebook for Mandarin Chinese are presented. The catalog and rolebook are part of the communication/language objectives-based system (C/LOBS), which supports the front-end analysis efforts of the Defense Language Institute Foreign Language Center. The C/LOBS project, which is described in 13 volumes and an executive summary, functions as a subsystem of the instructional systems development approach currently in use in the TRADOC school system. Five job/duty positions and three languages were selected for field testing and system validation. The function catalog is a collection of common Chinese phrases, sentences, and structures used to express each language function within six function categories. The Mandarin elements listed in this catalog were collected using native informants. The function categories are as follows: managing communication; engaging in social rituals; seeking and imparting factual information; reporting, expressing, or inquiring about intellectual and emotional attitudes, and getting things done (suasion).
