Previous research suggests that most Puerto Rican students who have spent some years in the United States and then returned to Puerto Rico generally experience cultural adjustment problems, language difficulties, low self-esteem, and identity crises. This study compared attitudes of Puerto Rican return migrant students (those who have returned to Puerto Rico after living for 3 or more years in the United States) with attitudes of Puerto Rican circulatory migrant students (those who constantly move back and forth between Puerto Rico and the United States) concerning school, teachers, and self-concept in Puerto Rico and in the United States. The Inventario de Percepcion al Ambiente Escolar, an attitude questionnaire, was used to elicit responses from 117 migrant students. The research results indicated that return migrants had more positive feelings toward school, teachers, and self in Puerto Rico than in the United States, while the converse was true of circulatory migrants, who demonstrated more positive attitudes toward school, teachers, and self in the United States.
