on bilingual education of its predominantly Hispanic student body, including recruiting about 330 teachers from Mexico, Spain, Central and South America, Puerto Rico, China, and the Philippines from 1998 to 2007. Bilingual educational services, as of 2014, are available for Spanish, Arabic, Vietnamese, Mandarin Chinese, Nepali, Urdu, and Swahili speakers. According to Texas Administrative Code BB § 89.1205 a language is eligible to have a bilingual program if 20 or more students are present in a school district who speak that language as their home language. Houston ISD offers three specialized programs, magnet programs, vanguard programs, and neighborhood vanguard programs. Each magnet program has a special focus and draws students throughout HISD. Each vanguard program is a gifted and talented program for students throughout HISD. A neighborhood vanguard program is a program designed for gifted and talented children zoned to a particular school. As of 2011, its 113 programs served almost 20% of the HISD student population.

Magnet schools are popular with parents and students that wish to escape low-performing schools and school violence. The members of the administration of schools losing students to higher-performing campuses, such as Bill Miller of Yates High School, complained about the effects. There are 55 elementary magnet schools, 30 magnet middle schools, and 27 magnet high schools. Some magnet schools are mixed comprehensive and magnet programs, while others are solidly magnet and do not admit any "neighborhood" students. In April 1997 a lawsuit against HISD seeking to end race-based admissions to magnet schools was filed on behalf of two white applicants to Lanier Middle School who were
