This research paper is an evaluation of the Dallas County Child Care Council's program and materials for training day care staff. Thirty-five white, middle-class 3-year-old children and their teachers participated in the study. The children were enrolled in two separate day care centers which served as control and experimental environments. The value of the staff training is described in terms of its effect on the children's levels of intellectual and visual perceptual functioning as measured in pre- and posttests by the Slossen Intelligence Test and Frostig Developmental Test of Visual Perception. Prior to the initiation of the educational program in the experimental center, the staff was trained through workshop sessions on child development theory. All parents were contacted in regard to the research; letters addressed to the parents of children in the experimental group also requested that they initiate activities related to those introduced in school. Results revealed that the children in the experimental group made (1) a measurable, but not significant, increase in intellectual functioning; and (2) a significant increase in perceptual functioning. Directions for further research are indicated and there is a brief review of day care literature and programs. (SDH)
