The inventory is an individually administered procedure designed to assess the cognitive skills of preschool children enrolled in the Living Room School (LRS) program. It was developed to measure change in the cognitive behavior of the 2- to 5-year-old child as well as to diagnose his performance patterns in order to formulate an individualized program commensurate with his needs. The 66 items are grouped into 11 subtests: Body Parts, Colors, Shapes, Size, Classification, Numbers, Positional Relationship, Zipper Frame, Button Frame, Scissors, and Large Motor Coordination. Items are grouped in a hierarchical order by two or three levels of difficulty. Any person, given the necessary training, can administer the inventory. The materials utilized are inexpensive and readily available. This inventory is in the developmental stage. (Author/RC)
