PRISM, the Pittsburgh Research-Based Instructional Supervisory Model, was initiated when the superintendent convened an Instructional Leadership Committee (ILC) to develop a plan for improving instruction and instructional leadership within the district. The Pittsburgh Public Schools' Learning Research Development Center then conducted a districtwide needs assessment on which the ILC based its 3- to 5-year implementation program. On the basis of this program, the four assistant directors for staff development prepared a plan of action. In consultation with selected administrators and teachers, the Staff Development Team (SDT) established a training program applicable to all Pittsburgh public schools and at all grade levels. Following several 1-day administrator inservice meetings, a total of 200 administrators were trained in 5-day inservice sessions conducted by the SDT for groups of no more than 40. Following sets of recommendations developed by the ILC and the SDT, PRISM is working toward a personnel evaluation plan for wider school-based implementation. The PRISM training process has followup components for every phase and is built on a sequence of five components essential to any staff program: (1) presentation of theory, (2) modeling or demonstration, (3) practice under simulated conditions, (4) structured feedback, and (5) coaching for application.
