The results of a study assessing the grammatical instruction needs of developmental English students and students of advanced English as a second language (ESL) at the University of Louisiana are reported. Faculty hypothesized that developmental English and freshman ESL students made many similar grammatical errors, and to test this hypothesis, a computer assisted test containing 32 multiple choice problems testing verb tense and subject-verb agreement was given to 113 developmental English students and 106 ESL students. Comparison of the groups' results showed many of the same errors being made and the same answers given by approximately equal numbers from each group. A second test administration at the semester's end showed that many of the common errors were corrected by both groups of students. It is concluded that both groups of students have the same needs in these areas and that texts with similar content could be used satisfactorily with both groups. Further investigation of grammatical areas in which the groups' needs may be similar and instructional materials can be used in common is recommended. (MSE)
