In studies conducted in the Baltimore City Public Schools by the Office of Pupil and Program Monitoring and Appraisal (OPPMA), pre-kindergarten pupils were found to be "growing scholastically". A program, Early School Admissions Program (ESAP) was based on nine objectives established to prepare pre-schoolers for "reading readiness" when they entered the kindergarten. To assess the success of the children and the program, a criterion-measure, based on Piagetian concepts, was constructed in cooperation with OPPMA and the Project Manager of ESAP. Reliability and validity of the Program Evaluation Measure (PEM) were established and found to be satisfactory, thereby, giving more credence to the growth indicators of the pupils. The profiles of the children (they were tested in October, November, December, January and May) demonstrated a significant pattern of achievement similarity as reflected by Dumas Model for measuring profile configurations. The Dumas Model for determining the similarity of profile configurations enables one to quantify the degree to which several profiles are shaped alike. (Author)
