A 2-year project was undertaken to develop, test, and distribute a video-based program to train low-income parents in engaging their 3- to 5-year-old children in highly motivating play techniques in order to enhance children's cognitive, social and motor skills for school readiness. An evaluation was conducted of the Year One phase of the training materials and procedures, and the effectiveness of the parent-training in leading to higher school readiness scores. The participants were the parents of 103 preschool children from inner city schools. The findings of the child assessments after 2 weeks of parent training indicate that children of parents who participated in the program showed significantly higher scores than the control children in the Total School Readiness Test, particularly in the areas of vocabulary, nature knowledge, general information, and awareness of good manners. This suggests that types of play-training methods and materials developed for the project can impact the ability of low-income parents to enhance their children's cognitive and social skills.
