enrollments. The school was filled to capacity and excess students had to attend other schools. In December 1991, Austin was one of the largest high schools in Texas, with 2,669 students. Due to the overcrowding, by that month Houston ISD trustees approved a plan to open a new high school in 1995 instead of in 1997. In 1992 superintendent Frank Petruzielo asked Jose Treviño to become the principal of Austin High. Carol E. Vaughn of the Houston Chronicle stated that for Treviño, who had served as principal of others schools, "it was the "principalship" at Austin High School where he emblazoned his name." In 1996 the school used eighteen temporary buildings, and the enrollment had increased to 3,000. By 1997, the new high school had not been constructed; area community leaders and parents anticipated the construction of César Chávez High School, as Austin and Milby were still overcrowded. Prior to 1997 residents zoned to Furr High School also had the option to attend Austin and Milby high schools; in 1997 the school district canceled the option. In the fall of 2000, Chávez opened and took most of Milby's traditional neighborhoods. In turn Milby absorbed some students from Austin. Areas that were zoned to Austin in 1998 were rezoned to Milby, In turn, Austin absorbed areas previously zoned to Furr and Yates high schools. In 2002 Treviño was promoted to the southeast district regional superintendent. In 2003 Linda Llorente, an Austin High alumna, became the principal. In 2005, the administration decided to open a new music program. A new Band Director was hired to build a new band which was given the nickname "Sonic Boom". In 2010, the Sonic Boom was selected out of more than 80 applicants nationwide to compete in the Home Depot Center Battle of the Bands, sponsored by Vh1 Save the Music Foundation. At the end of the day, the Grand Champion of the Battle of the Bands in Los Angeles was Stephen F. Austin's Sonic Boom who also headlined the HEB Holiday (Thanksgiving Day) Parade in Downtown. Currently the Sonic boom is preparing the celebrate its 10th anniversary. In 2007, a Johns Hopkins University study commissioned by the Associated Press included Austin in a "dropout factory" list of 42 Houston-area high schools; a "dropout factory" school is where at least 40% of the entering freshman class does not make it to their senior year.
