Teaching students who receive special education services in integrated settings requires intensive staff development and on-going training. Region 16 Education Service Center in the Texas panhandle serves 65 rural school districts covering 25,000 square miles and 80,000 students. In 1996, with direction and funding from the state legislature, Region 16 began to develop a regional plan for staff development on inclusion. Focus groups and an outside consultant identified issues, services, and products needed, and suggested changes in services to support diverse learners in inclusive settings. A needs assessment survey sent to appropriate personnel ranked needs, changes, and service delivery. Survey results indicated that the preferred service delivery model was training at "cluster sites" selected to minimize participant travel time. A series of training sessions held at sites in 1996 and 1997 included topics on meeting the needs of diverse learners; support models for inclusive education; support, staff, and scheduling; IEP process; strategies for handling behavior issues; and creative solutions to barriers in inclusive education. The next component of Region 16's plan involved identifying demonstration sites that would receive technical assistance. Other components included administrative seminars, creation of a video library, and training of a team of inclusion resource experts. Additional types of support included a newsletter, half-day training sessions, and other training opportunities. Evaluation of the regional plan emphasized determination of the extent to which students with disabilities were being served in integrated settings. A demonstration site faculty survey and a statistical look at campus-level changes in student placement and use of personnel yielded very positive results, which were attributed to the impact of cluster site training.
