The isparity in fudning, that is. In the early 90's if I recall correctly, Edgewood Independent was defendent in a law suit against the state. The issue, EDGEWOOD ISD V. KIRBY, eventually brought about educational funding equality in Texas. It was part of a lengthy battle that started in the early 70's.

The Mexican American Legal Defense and Educational Fundqv filed suit against commissioner of education William Kirby on May 23, 1984, in Travis County on behalf of the Edgewood Independent School District, San Antonio, citing discrimination against students in poor school districts. The plaintiffs charged that the state's methods of funding public schools violated at least four principles of the state constitution, which obligated the state legislature to provide an efficient and free public school system.

The Edgewood lawsuit occurred after almost a decade of legal inertia on public school finance following the Rodríguez v. San Antonio ISD case of 1971, which asked the courts to address unfairness in public school aid. The Rodríguez plaintiffs ultimately lost in the United States Supreme Court in 1973.

In its opinion deciding the case (1989), the Texas Supreme Court noted that the Edgewood ISD, among the poorest districts in the state, had $38,854 in property wealth per student, while the Alamo Heights ISD, which is in the same county, had $570,109 per student. In addition, property-poor districts had to set a tax rate that averaged 74.5 cents per $100 valuation to generate $2,987 per student, while richer districts, with a tax rate of half that much, could produce $7,233 per student. These differences produced disparities in the districts' abilities to hire good teachers, build appropriate facilities, offer a sound curriculum, and purchase such important equipment as computers.
The decision wasn't arrived at without a bitter fight and the plan settled on was dubbed the Robin Hood plan, consolidating the 1,058 school districts into 188 County Education Districts to assure that public money spent per student would be equal.
In 2002 Per Pupil expenditures:
Alamo Heights ISD $7,664
Edgewood ISD $6,764
Its not great, but is a damn sight better than it used to be.
