The Georgia Principal Assessment System (GPAS) is a set of practically administered instruments and procedures for assessing performances of school principals. The instruments and procedures were developed over a four-year period of Project Results Oriented Management in Education (Project ROME) at the University of Georgia. Each of the instruments contains statements of principal performance that have been validated through large-scale research in Georgia. This document provides a brief description of the GPAS and its developmental history, its administration and scoring procedures, and potential school uses of the instruments. (Author/MLF)
