A site in Milwaukee was selected for a series of high-risk population survey. This area was rated in the lowest category for Milwaukee in terms of median educational level and income, and in the highest in terms of population density per living unit, percent housing rated as dilapidated, and unemployment. A pool of candidates composed of mothers with full-scale Wechslar Adult Intelligence Test IQs of 75 or less was randomly assigned to either the experimental or control condition. Forty mothers meeting this IQ criterion had babies over an 18 month period and were assigned as either experimental or control families. All families selected were of Negro extraction. The experimental intervention is comprised of two components: the infant stimulation program, and the maternal rehabilitation program. The former program is designed to facilitate intellectual development of very young children. The plan is concerned with a staff to manage and arrange instruction for children, a physical location which promotes learning, and the stimulation program. The latter program was initiated to better prepare the experimental mothers for employment opportunities and to improve their homemaking to teach the mothers basic academic tools necessary for vocational adaptability and an occupational training program to teach specific vocational skills.
