Each year, Missouri gives standardized tests to all public school kids grades 3 through 8 to gauge their proficiency in math and English. In the 2023–2024 school year, only a tenth of KIPP Wonder’s kids who took the tests scored “proficient” in English. That’s 31 points below the state average. But it’s just a snapshot—and, in large part, due to factors outside any school’s control, such as community and family resources. Missouri also calculates a growth metric, one that Collin Hitt, the executive director of Saint Louis University’s education policy group, PRiME Center, calls “the best in the country.” It asks the question: How far did students move forward in a subject, regardless of where they started, and in comparison to other similarly situated students? And on that metric, KIPP Wonder showed the second largest average leap in English of all public elementary schools in Missouri, according to a PRiME analysis. (They were second only to a school in the Ozarks.)
