Annexation is a process set out in the Texas Education Code through which community colleges expand their taxing districts through annexation of territory that lies within their state-designated service area. It most commonly occurs through "annexation by election."
"Annexation by election" is when residents of a service area community - often a school district but occasionally a city or a county - petition to join the college district. If the college trustees determine that the petition is valid and signed by the proper number of registered voters, an election is held in the community. If the measure wins voter approval, the community is officially part of the college district's taxing authority and the community begins paying ad valorem taxes to the college district in exchange for increased services and reduced tuition.
