The Tuba City Elementary School, located in a Bureau of Indian Affairs Sub-agency Headquarters on the Navajo Reservation in Arizona, has conducted a teacher aide program since August 1965. Specific teacher aide duties have been developed for routine record-keeping, small group and individual instruction, and supervisory activities. Teacher aides are used in ungraded primary grades, in intermediate grades, and to assist nurses, librarians, and home visitation officers. The aides are trained in operation of equipment, reporting procedures, and classroom operations through inservice training programs. Three aides attended a summer institute for teacher aides at Northern Arizona University for undergraduate credit. Seniors in high school who wish to become teacher aides upon graduation may participate in a 28-week training program during which time they receive $1.25 an hour. (JH)
