In an effort to reach widely dispersed Indian children and provide them with an early education that will encourage them to enroll in conventional schools after the fourth grade, Jesuit missionaries in a mountainous rural area of Mexico have provided a radio school since 1955. The evaluation reported here reveals that the radio schools have been most useful to those who are not disadvantaged, making integration of the rural Indians into the national culture and economy even more difficult. After an analysis of the problems of the radio schools, a drastic reform plan is presented. (RH)
