These are the appendixes for the report, "College Enrollment and Completion among Texas High School Graduates with a Disability." The study used student-level administrative data from Texas, available through the data repository at the Texas Education Research Center at the University of Texas. The data repository contains administrative records for all students who enroll in a Texas public school or Texas college. The files required for this study were provided to the Texas Education Research Center by the Texas Education Agency, which collects K-12 accountability, performance, and financial data from Texas public school districts, and the Texas Higher Education Coordinating Board, which collects postsecondary enrollment and completion records from Texas public and private colleges. The Texas Education Research Center records contain a unique student identifier that permits linking of secondary and postsecondary records while maintaining student anonymity. Appendix A describes the data sources used, data procedures, population characteristics, and analysis methods. Appendix B includes supplemental findings for enrollment in Texas colleges and attainment of college outcomes among high school graduates with a disability, by Texas region. Appendix C provides the Cox index score for each group contrast presented in the main report. [For the full report, see ED608925; for the study snapshot, see ED608932.]
