In 2023, as part of a $1.26 billion bond package by Fort Bend ISD, a proposition was made calling for the construction of a new $222 million rebuild of Clements on the current site's athletic facilities.

The move was made due to long-standing foundation issues; large parts of the school are sinking or being raised up, with cracks becoming so wide that they could be used to pass books between classrooms.

[citation needed] In 2024, Clements was ranked number 18 on the Best High Schools in the Houston-Area list,[15] The average 2019 SAT scores were[16] Math 690 and Verbal 660.

[citation needed] Clements has the largest number of degrees in the National Speech and Debate Association East Texas District.

Following the call, school officials promptly discovered the website where a 17-year-old alumni was distributing the map as a mod for Counter-Strike.

[24][25] Clements, along with the other Fort Bend High Schools of Elkins and Dulles, was subject to an act of cyberterrorism when a list titled Whimsical Girls of FBISD was posted on Facebook in April 2010.

The group was attempting to move chairs set in place for AP testing from the gym to the roof of the school as a senior prank.

Additionally, the 11 students were forced to walk around Clements High School with signs around their neck reading "What I did was a crime not a prank," for four hours.

[28] On October 15, 2016, Brian Yuen, a 17-year-old member of the school's aquatics team, experienced a major medical emergency while competing at the Don Cook Natatorium.

A moment of silence was held at a football game between Ridge Point and Dulles High Schools that day, with cheerleaders and attendees wearing blue, Yuen's favorite color.

[30][31][32] On December 11, 2023, the principal of Clements High School, Brian Shillingburg, was arrested on suspicion of soliciting a prostitute/other payor.
