The correct answer to this open question is the following.
In 1949, the law that increased state funding and established the Texas education agency (TEA), that carries out the state's educational program was the Gilmer-Akin Law.
This law was passed with the goal of raising the standards of the schools in the state of Texas and also tried to end inequalities in the educational system of the state. Due to the law, school districts passed from 2500 to 2900. The government tried to balance funding to reduce the gap between school districts, increased the salaries of teachers, and elected a new State Board of Education.
