In accordance with House bill 5 of the 83rd Texas Legislature, Lake Creek High School offers instruction in "core foundation" subjects and "endorsement pathways."

Foundation courses include traditional subjects such as English, math, science, and social studies.

[12] HB5 designates four "endorsement pathways" that students may follow: Arts and Humanities, Business and Industry, Public Service and STEM (Science, Technology, Engineering, Mathematics).

For Public Service, students may take courses in education, health science, fashion and law enforcement.

[13] The school offers competitive athletics in the following sports: American football, volleyball, basketball, soccer, baseball, softball, track, cross country, swimming, tennis and golf.

[14] On June 4, 2022, the Lake Creek High School softball team won the 2022 University Interscholastic League 5A State Championship at Red and Charline McCombs Field at the University of Texas at Austin by defeating the Georgetown High School (Texas) Eagles 7–0.

They were the first team from Montgomery County to advance to the fourth round since The Woodlands College Park High School did so in 2012.

[17] After an inaugural season with one win, Lake Creek's boys' soccer team was restructured.

[5] In March 2018 an area resident asked the district to construct a sound barrier so his house would get less noise from air conditioners used for the school.
