Yet both the assumptions -that the Mexican schools should prepare students for Mexican adulthood and that American schools should prepare students for U.S. adulthoods- are incomplete or inadequate for a growing portion of the student population. That is, students who spend periods of their school -age life in the United States and some others in Mexico. In 1998, Mexican demographers estimated that almost 900,000 school-aged children born in Mexico lived in the U. S. (Corona and Tuirán, 1998). Additionally, they had observed this migratory process was a two-way movement: between 1987 and 1992, about 161,000 minors returned to Mexico. However, their research did not tally how many of these minors would attend Mexican schools, nor did it look into how those who did enroll fared.
