This report describes the room arrangement, design, and appearance of 152 Title IV-A Day Care centers in Philadelphia. A series of 27 items on a section of the Daily Care, In-Room Observation Guide was used to provide an overall description of rooms in day care and to identify differences in features for different types of programs. Data were analyzed by four program types: (1) infant/toddler, (2) preschool/school age, (3) school age, and (4) specialized. The overall typical room is described in terms of such aspects as interest areas, furnishings, storage of materials, cleanliness, carpeting, acoustics, lighting, windows, access to outdoors, hard and soft areas, high and low areas, and structures that children can get inside of. The typical room for each program type varied only slightly from the typical room for all programs. Specialized programs had hard and soft areas built in for tactile stimulation, and infant/toddler and specialized programs had carpeted areas. Approximately half of the report consists of data presented in tabular form. (Author/JMB)
