Welcome to Clayton High School!

Clayton High School (CHS) is a nationally recognized, award winning public high school in Clayton, Missouri. Known for academic excellence and high expectations, CHS challenges students to grow, achieve and prepare for success in college and beyond.

At CHS, students are supported every step of the way. The school's dedicated faculty work closely with students and families to ensure that every learner has the guidance, resources and encouragement needed to reach their full potential.

CHS offers Honors and Advanced Placement courses in nearly every subject, which allows students to explore their interests while building strong academic skills. Beyond this, co curricular programs enrich the experience by helping students discover their passions, develop leadership skills and become confident, capable, lifelong learners.

Each year, nearly 90% of CHS students participate in extracurricular activities and athletics. Greyhound athletes are encouraged to strive for excellence, teamwork and personal growth, with many continuing on to compete at the collegiate level.
