In the School District of Clayton, assessments are not just about measuring performance; they are powerful tools that help us understand each student’s strengths, needs and growth over time. The District’s comprehensive assessment plan reflects our belief that data should drive action. Assessment results are reviewed regularly by teachers, administrators and support teams to identify trends, celebrate successes and tailor supports where they are needed most. This collaborative, data-informed approach ensures that every decision we make—whether at the classroom, school or District level—is student-focused. Below is an overview of the assessments used throughout the District. The data helps inform our ongoing commitment to continuous improvement and student success.

I n a District where academic excellence is the norm, intentional steps are taken to nurture students’ social, emotional and physical well-being. This dedication is evident across classrooms, from the District’s youngest learners at the Family Center, who engage in activities that help them identify and express emotions, to middle school students at Wydown who collaborate in small groups to strengthen relationships with their peers. Beyond these daily experiences, the District continues to prioritize student well-being in meaningful ways. One example is the Wellness Center, the first of its kind in the Midwest, which offers students a dedicated space to focus on mental health. Located on the lower level of Clayton High School, this welcoming space provides opportunities for brain breaks, wellness events and easy access to resources that support mental and emotional health. At the elementary level, the CharacterStrong program is driving meaningful social and emotional growth. Through engaging lessons that include songs, games and activities, students learn empathy, kindness, interpersonal skills and resilience. For those needing additional support, teachers and staff can connect students with extra resources through program referrals. These efforts are making a measurable difference. According to the District’s 2024 data dashboard, more than 77% of students in grades 3–5 report feeling a strong sense of belonging—a score significantly higher than the national average and one that has continued to rise since the District began participating in the Panorama survey in 2022. While progress toward these goals is ongoing, these achievements, along with the list of completed activities below, reflect the District’s intentional and focused commitment to supporting every student’s well-being.
