This paper describes the early childhood special educator's use of the Five P's (Parent/Professional Preschool Performance Profile), a new assessment tool by Judith Bloch, developed by the Variety Preschooler's Workshop (Syosset, New York) for use with children with emotional and developmental disorders functioning on a preschool level. The Five P's tool consists of 15 scales focusing on five areas of development: (1) routines and self-help skills, (2) motor, (3) language, (4) social and (5) cognitive skill development. Also included are a Learning Style and Effective Teaching Methods page, IEP forms, and a Graphic Profile. It is a multivariate tool which involves the child's two primary caregivers, the teacher and the parent, in a shared assessment of the child's functioning in the classroom and the home. Information from the Five P's does not replace evaluations by clinicians but is intended to integrate and supplement these reports. The Five P's provides the teacher with a systematic method for assessing a child's skill and behavior repertoire and linking this evaluation to goal selection, curriculum planning and reevaluation. A detailed description of how the Five P's tool is used by the classroom teacher is given, with a case study to illustrate the process. (Author/CL)
