Recent research in phonological disorders has focused on phonological processes, to determine the number of children using particular processes. This study investigated individual patterns of phonological process occurrence in nine phonologically disordered children. The purpose of the study was to determine frequency of occurrence of each process for each child and frequency of occurrence of unusual processes. Results indicated that a small, basic subset of phonological processes seemed to account for the majority of errors made by these children. Unusual processes were primarily changes in word structure. Within the common framework of basic and unusual processes, the children realized the processes in unique ways.
