This article presents a rationale and description of GCS, or Grammatical Coding System. GCS is a general-use grammatical coding system designed for research on the language of normal and language-impaired children or adults and is especially useful for studies in which a relatively large number of participants are involved. It implements recent theoretical developments in linguistics to characterize development and/or language disorder in children and adults. In addition to the coding system, a computerized method for reading coded transcripts and calculating relevant descriptive statistics is presented. A full coded transcription is included in the Appendix. A detailed GCS manual may be downloaded from www.psychonomic.org/archive.
