Many developments in education took place in the 1990s in Alief. In 1993, Alief ISD instituted a rule which made passing the statewide standardized test, the Texas Assessment of Academic Skills (TAAS) Exit Exam, a requirement for high school graduation. Many parents protested the measure. In 1995, voters decided to allow Alief ISD to build the Hastings and Elsik Ninth Grade Centers. In 1998, voters approved funds for Alief ISD to use to build a new high school, which would later become Alief "Doc" Taylor. The period was also marked with political scandals. In 1991, a ballot box from the Boone Elementary polling location containing over 700 ballots went missing after the poll closed.
