The American Civil Liberties Union and the ACLU Foundation of Texas have filed a civil rights complaint against the Austin Independent School District over the opening of a pair of two single-sex middle schools, the Gus Garcia Young Men’s Academy and the Bertha Sadler Means Young Women’s Leadership Academy. The civil rights organizations want an investigation by the U.S. Department of Education into whether the new schools discriminate against students based on sex and race. The district transformed Pearce and Garcia middle schools into the single-sex campuses. Both schools’ student bodies are mainly Hispanic and African-American. The ACLU claims that Pearce and Garcia were two of AISD’s poorest-performing schools. As of Wednesday, AISD officials said they had not seen the complaint.
