Tex. Educ. Code § 29.154
The commissioner of education, in consultation with the commissioner of human services, shall monitor and evaluate prekindergarten programs as to their developmental appropriateness. The commissioners shall also evaluate the potential for coordination on a statewide basis of prekindergarten programs with government-funded early childhood care and education programs such as child care administered under Chapter 44, Human Resources Code, and federal Head Start programs. That evaluation shall use recommendations contained in the report to the 71st Legislature required by Chapter 717, Acts of the 70th Legislature, Regular Session, 1987. For the purpose of providing cost-effective care for children during the full workday with developmentally appropriate curriculum, the commissioners shall investigate the use of existing child-care program sites as prekindergarten sites. Following the evaluation required by this section, the commissioners, in cooperation with school districts and other program administrators, shall integrate programs, staff, and program sites for prekindergarten, child-care, and federal Head Start programs to the greatest extent possible.
