A SHAC is a school board appointed advisory group of individuals who represent different segments of the community. By law, a majority of the members must be persons who are parents of students enrolled in the district and who are not employed by the district. Texas law (Texas Education Code, Title 2, Subtitle F, Chapter 28, Subchapter A, §28.004) requires the establishment of a SHAC for every school district. SHACs are required to meet at least four times each year.
