In January 2003, over 1,000 students walked out of class in protest of the district-wide change from a traditional eight-period schedule to a block schedule. The then-peaceful protest turned into what was later called a riot when the El Paso Police and SWAT teams demanded that the students return to class. When the students were slow to mobilize, the officers began to push the students towards the building, causing some students to retaliate with rocks and water bottles. Ultimately, several students and some teachers were arrested. The school was placed under lockdown for the remainder of the school day, though many students had left it within minutes of the riot's beginning. The riot made its way to The New York Times due to police brutality controversies. The school district still uses traditional 8th period scheduling.
