According to Section 29.123 of the Texas Education Code, the "Texas State Plan for the Education of Gifted/Talented Students" (G/T) forms the basis of program accountability for state-mandated services for G/T students. In the Houston Independent School District (HISD), G/T students were served through one of two program designs: Board-approved Vanguard/Magnet or Vanguard Neighborhood. This evaluation report summarizes the effectiveness of the Vanguard Program during the 2013-2014 school year. It evaluates the degree to which the Vanguard Program operated in compliance with the policies and procedures developed by the legal and administrative authorities as well as the District's 14 G/T Standards approved by the Board of Education on March 8, 2007. Among the findings are: (1) In 2013-2014, a total of 32,906 students attending 259 elementary, middle, and high schools participated in the district's Vanguard Program, reflecting 16.9 percent of the district K-12 population, representing a slight decrease from 17.0 percent in 2012-2013; (2) When comparing the demographic profile of those participating in the Vanguard Program to the district's demographic profile, African American, Hispanic, and economically disadvantaged students were underrepresented, while, White and Asian students were over-represented; (3) For 2014, a total of 9,928 Advanced Placement (AP) exams were taken by 4,821 G/T students and 51.5 percent of the scores were three or higher on a scale of one to five, showing an increase in participation rates from 2007; and (4) In May of 2014, 376 HISD G/T students took a total of 1,165 International Baccalaureate (IB) examinations, where 63.0 percent scored a four or above on a scale from one to seven. This reflects an increase in participation from 2007.
