Kehrs Mill Elementary serves kindergarten through fifth grade as a regular public school in Chesterfield, part of the Rockwood R-VI district. It is a school where academic performance stands out. On the state assessments given in grades three through five, the share of students scoring proficient or above was consistently strong in math, English language arts, and science. Compared to all other districts in St. Louis County, Kehrs Mill’s overall proficiency index places it in the top quartile. That means a student here is very likely to be working at or above grade level by any standard the state measures. The school does not serve grades that take high school exit exams, so there is no graduation rate to review, but for an elementary building the academic picture is clear: this is a high-performing environment.
The student body is relatively small for a K-5 school. A very small share of students qualify for free or reduced-price lunch, which signals that the school serves a predominantly affluent community. Racially, the majority of students are white, with a noticeable Asian population and smaller shares of Hispanic, Black, and multiracial students. Data on students with disabilities and English learners was not available; a parent considering the school may want to ask the school directly about the support available for those groups. The school building sits in Chesterfield, a car-oriented western suburb of St. Louis that has no traditional downtown. Residential areas are established and spread out, with commercial development concentrated in the Chesterfield Valley along Interstate 64. Housing in the area is expensive. The county housing market shows elevated home values and rents, which matches the low poverty rate seen in the school.
Rockwood R-VI, the district managing the school, has recently gone through several changes that affect families. Voters approved a bond issue in 2024 that funds a new elementary school to handle enrollment growth, along with safety upgrades, HVAC replacements, and technology across the district. A previous bond in 2022 paid for security entrances and facility renovations. Starting in the 2023-2024 school year, the district shifted its elementary literacy curriculum to align with the science of reading, abandoning the previous balanced literacy model. That change touches every elementary classroom in the district, including Kehrs Mill, and represents a lasting shift in how reading is taught.
For a family trying to understand whether this school fits, a few things matter. The academic track here is very strong, and the peer environment is one where most students come from homes with considerable resources. The housing market in Chesterfield is expensive, so families living here typically have the income to support that. The suburban setting is car-dependent, with no walkable commercial center. Parents who value high test scores, a low-poverty student body, and a district that invests in facilities and curriculum will find Kehrs Mill appealing. Parents who need targeted special education or English learner services should seek more detail from the school, because the public data does not show how those populations are served. Overall, Kehrs Mill is a solid, well-regarded elementary school in a district that has made deliberate investments in its future, and the numbers on student achievement back that up.
