The purpose of this study was to investigate various categorization skills in f.irst grade children who are representative of three different levels of expressive language development. In an attempt to determine Whether there were significant differences in categorization ability among the thirty-six first grade children as a function of their level of expressive language development, seven categorization tasks were administered to three groups of children. Twe~ve children with normal expressive language development, twelve children with a mild-moderate expressive language delay, and twelve children with a severe expressive language delay were selected for comparison in the categorization tasks. The results indicated a significant difference in categorization skills between the children with normal expressive language development and the children with a mildmoderate expressive language delay. A significant difference in categorization skills was also found between the children with normal language development and the children with a severe expressive language delay.
