Beginning in August 2016, SHHS began offering an opportunity for students to participate in an exclusive educational program called Connect.

In March 2011, South Houston High School unveiled the "Wall of Honor" to spotlight outstanding alumni who have made contributions to the community, nation and world.

54 alumni were honored, including five who gave the ultimate sacrifice in the U.S. Armed Services in Vietnam, Iraq and Afghanistan.

Each year during the Homecoming celebration the school hosts an open house for alumni and inducts new members to the Walls of Honor.

South Houston High School competes in football, soccer, basketball, volleyball, softball, dance (Jannettes), baseball, track and field, cross country, cheerleading, golf, marching band, tennis, powerlifting, bowling and swimming.
