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) of 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. Report sections are organized around findings for the study's major research questions. Key findings are summarized for Texas single districts and SSAs. "Section 2, Method" gives a description of the instrument development and validation process, the four surveys used in the study, and the data collection procedures. The authors also discuss the generalizability of the study to public schools statewide.

This section specifically addresses the special education personnel needs in Texas public schools.

This section also identifies the professional development areas in which special education teachers and other professionals had completed training as well as the areas in which they desired additional training.
