Memorial is part of the Spring Branch Independent School District (SBISD) and serves grades 9 through 12.

[citation needed] At the time, Memorial's main rivals were the Spring Branch Bears and Westchester Wildcats.

[citation needed] Today, Memorial is the oldest high school still operating in Spring Branch ISD.

Every building in the school was gutted and refurbished, outdated facilities were replaced and the campus was made more secure.

[16][17] Memorial also has a formerly successful football team, which went to the state semifinals in December 2010 in the Division II bracket.

[20] However, in 2024, the Memorial tennis team was beaten in the regional finals by Seven Lakes High School, thus ending their 15 year streak of competing in the state championship.

[note 1] It was also ranked 239th[40] and 233rd[41] in U.S. News' 2012 and 2013 lists, respectively, of top high schools in the United States.

[43] The school achieved "recognized" status in the accountability ratings system by the Texas Education Agency in 2000, 2001, 2002, 2004, 2005, 2008, 2009, 2010, and 2011.

[84] Memorial would face controversy in May 2019 over a spirit week tradition of "Thug Day' which was tweeted out by an upset student and went viral.

[85][86][87] Critics would claim that the event was racially insensitive to African-Americans and was an example of cultural appropriation due to the utilization of basketball jerseys, cornrows, do-rags, gang signs, and fake tattoos.

'[89][90] Students went on to claim that campus tension increased as a result of the fallout, alongside mixed reception from alumni.

[88][91] In December 2023, a teacher at Memorial High School was placed on administrative leave after being accused of having inappropriate sexual misconduct with a former student.
