In Senate Bill (SB) 2 (83rd Texas Legislature, Regular Session, 2013), the Texas Legislature added Texas Education Code (TEC) § 12.1013 (a)-(d). This legislation required that charter school performance to be compared to comparable traditional public schools. This report responds to that mandate, using Texas' P-20/Workforce Repository data for the 2012-13 school year. In particular, the following summary reviews descriptive results comparing charter school types to matched traditional public schools on four Performance Indices and student mobility, then specifically highlights Alternative Education Accountability charter schools. The Performance Indices were first introduced in 2013 and include: (1) Student Achievement; (2) Student Progress; (3) Closing Performance Gaps; and (4) Postsecondary Readiness.
