The doctoral dissertation focused on: the perceptions of school administrators, teachers, and aides on teacher aide functions in the New Mexico Migrant Project; comparing the results with student needs; functions not ascribed to aides within the State Department of Education and the National Migrant Project's guidelines; and making recommendations to the State Department of Education, the New Mexico Migrant Project, and the National Migrant Project. The study had 3 phases: a 250-item questionnaire given to the researcher's doctoral committee and 6 public school administrators; a revised questionnaire given to 15 experts on paraprofessionals in education; and a final questionnaire given to New Mexico Migrant Project personnel. Statistical analyses consisted of one-way analysis of variance and Duncan's Multiple Range Test. Findings showed no significant differences in the perceptions of the functions between aides and administrators and aides and teachers, but significant differences between teachers and administrators as to the bilingual and professional development functions; and between jury members and administrators, teachers, and aides as to the monitorial, school-community, bilingual, and professional development functions.
