Suggested guidelines for designing indoor lighting and outdoor play space for child care centers are outlined in this booklet. It is recommended that, by focusing on the psychological and physiological needs of the children, decisions as to lighting, color, and playground design will evolve naturally. The guidelines were prepared based on the fact that young children in their learning environments need activity, opportunities for manipulating things, for exploring, for interacting with their peers, and for producing and changing things around them.
