Four young children who were learning English as a second language were observed during their participation in an English Language Development class in a school in the North Texas area. Demographic data and checklists were used to describe progress in expressive language and the key vocabulary approach to beginning literacy as adapted by Trietsch and Monk. Data from the interviews with the classroom teachers of the subjects and anecdotal records were used to describe the interaction of the subjects with other English-speaking children and adults. Comparisons were made between progress in writing the key vocabulary and progress in expressive language and between progress in writing the key vocabulary and the progress of interaction with other English-speaking children and adults. The subjects progressed in literacy in English as a second language while learning English as a second language.
