The East School Assistance Center (ESAC) is an organizational unit of Toledo Public Schools that provides psychological and special-education services to the East Toledo region of the district. This paper presents findings of a study that evaluated the quality and efficiency of the center's services. The delivery model features a regional location and shared housing, school-assistance teams, an emphasis on intervention, a steering committee, weekly staff meetings, cross-categorical special-education supervision, evening hours, and school-community agency collaboration. Data were obtained from a survey of regular-education K-8 teachers, all special-education teachers, and school administrators in the East Toledo service region. The return rate was 70 percent for administrators, 39 percent for regular-education teachers, and 47 percent for special-education teachers. The center's records were also analyzed. Survey respondents perceived an improvement over the services previously provided in the area. Improvement occurred across the following dimensions--availability, responsiveness, timeliness, pleasantness/professional behaviors, utility, and satisfaction. However, the data did not indicate that the center's service-delivery model was more or less efficient than the traditional model, in part because the workload of psychologists and output were difficult to measure. If the district chooses to adopt the East Center model throughout the district, it should focus on the selection and training of center personnel for successful implementation. Nine tables are included. (LMI)
