The Draw-A-Classroom Test was designed to provide information (1) on how a child perceives the world and how this world is influenced by school experiences and (2) about the developing concepts and ideas in the child's mental, emotional, and social areas of growth. This test is one part of a larger Study of Achievement, and has been administered to a base population of 8,695 children over a six-year period. The test was administered by giving each child paper, crayons, and standard instructions to draw his classroom. Upon completion, the child's explanation of his drawing was affixed to the drawing. A coding system based on a "constant" foundation was devised. Three constants were evaluated: space, people, and objects. A total of 83 analysis categories have resulted, with an average of over 80% interrater reliability. It is thought that the scoring results, currently being analyzed, will provide a valid look at the child's psychoeducational world through a drawing. (JS)
