This study supports efforts by the U.S. Department of Education, Office of Special Education Programs (OSEP) to foster greater state accountability and establish data-driven planning and self-assessment processes that help states and schools to address provisions of the recently enacted Individuals with Disabilities Education Improvement Act (IDEA, 2004). In response to state-level requirements, the Texas Education Agency (TEA) asked Region 4 Education Service Center (ESC) to facilitate the second statewide study of special education professionals personnel needs. This study, which was authorized in December 2004, augments the initial "Statewide Study of Special Education Professionals' Personnel Needs" conducted by the Texas Center for Educational Research (TCER) and published in September 2001. The current study was designed to identify existing shortages in special education teacher and other professional positions, to investigate the various issues that appear to influence turnover in these positions, and to identify effective approaches to retention. Appended are: (1) Staffing Levels in Single Districts; (2) Staffing Levels in SSA Participant Districts; (3) Staffing Levels in SSAs; and (4) Staffing Levels for Charter Schools Including Single Districts, SSAs, and SSA Participant Schools.
