The Preschool Version of the High/Scope Program Quality Assessment (PQA) is a ratings instrument for evaluating the quality of early childhood programs and identifying staff training needs. The assessment was developed for use in all center-based preschool and child care settings, not just those using the High/Scope educational approach. This document is comprised of the PQA's user guide for Head Start, the PQA administration manual, and the PQA assessment form. The Head Start user guide relates the PQA to Head Start performance standards. The administration manual includes information on the PQA's potential uses, directions for administration, and test reliability and validity. The 72-item assessment instrument is organized into 7 sections: (1) learning environment; (2) daily routine; (3) adult-child interaction; (4) curriculum planning and assessment; (5) parent involvement and family services; (6) staff qualifications and staff development; and (7) program management. The assessment form provides space for information on the program and the rater, and provides guidance for making ratings on 5-point scales for each of the 72 items. Anchors are provided for 3 of the 5 points, and space is provided for recording supporting evidence or anecdotes related to each rating. A summary sheet completes the assessment form. (KB)
