Summary

Clayton High is a public high school serving 844 students in grades 9-12 in the highly-ranked Clayton School District in Clayton, Missouri. The school consistently ranks among the top high schools in the state, with exceptional academic performance and student outcomes.

Clayton High's students demonstrate remarkable achievement, with high proficiency rates on state assessments that far exceed the state averages. For example, in the 2024-2025 school year, 83% of students were proficient or better in English II, compared to the state average of 52.9%. The school's performance on subject-specific exams, such as Algebra I (73.9% proficient), Biology I (72.9% proficient), and Algebra II (90.2% proficient), is also significantly higher than the state benchmarks. Additionally, Clayton High maintains an impressive four-year graduation rate, ranging from 97.1% to 99.0% over the past few years, well above the state average.

While Clayton High excels in supporting the academic achievement of many student subgroups, the performance gap between its low-socioeconomic status (SES) students and the rest of the student population is an area of concern. The school's relatively low percentage of free and reduced-price lunch recipients (7.58% in 2023-2024) compared to nearby schools like Normandy High (50.4%) and Soldan International Studies (50.1%) suggests that Clayton High may need to strengthen its efforts to serve and support economically disadvantaged students.
