[citation needed] In 2011 voters in PISD approved of a bond, which includes building a new competitive gymnasium for Rayburn, set to open in September 2013.

Some Rayburnites eventually adopted Yosemite Sam from Warner Brothers Looney Tunes as the school's informal mascot.

Most recently, in 2014 the boys soccer program earned Rayburn their first district title in at least a decade.

Sam Rayburn is classified as 6A for UIL sports , as the student population is expected to eclipse 3,000 for the 2014–15 school year.

PMHS opened in 2003, taking away much of the enrollment from Rayburn and South Houston High School.

Since Fall 2012, however, Rayburn and the rest of the PISD schools have been separated from Deer Park in district athletics.
