Mehlville School District

The Mehlville School District, officially the Mehlville R-9 School District or Mehlville R-IX School District, is a public school district based in south St. Louis County, Missouri. It serves the unincorporated, census-designated communities of Mehlville, Oakville, Concord, and Lemay. Its offices are presently located on Mehlville High School's campus, with plans to eventually move into a vacant office building just north of the campus.

The district formally began with the first graduating class of Mehlville Senior High School in 1930. The district as we know it today first consisted of smaller, independent educational entities working under a feeder school system.

In the 1950s and 60s, the state government of Missouri began to combine the thousands of small, rural schools into larger districts. So, in October 1951, the Mehlville, Oakville, Point and Washington districts consolidated their schools into a single, reorganized school district, which became the modern Mehlville R-9 School District. Years later, the district dropped the R-9 title from its name, becoming the Mehlville School District. The state Department of Education, however, continues to refer to the district as "Mehlville R-9." or "Mehlville R-IX."

After a rapid increase in enrollment of elementary and secondary students as a result of the increase of the area's population, bus transportation was introduced in 1951, and the district was forced to construct more educational facilities to meet the growing enrollment. Schools like Bierbaum and the old Bernard Elementary were built for this exact purpose.

In 1956, the district received the official title to 45 acres formerly part of the Veterans Administration Hospital Reservation at Jefferson Barracks; the land is now home to Beasley Elementary.

On May 11, 1964, the district voted to annex the Jefferson Barracks School District, acquiring what is now known as the Jefferson Barracks Building and numerous smaller facilities.

In the mid-to-late 1960s, the district continued to expand, constructing Trautwein and Wohlwend Elementary in 1964 and 1969, respectively.

Oakville Senior High School was established in 1970 due to overcrowding at Mehlville High School.

MOSAIC
MOSAIC, often referred to as Mosaic Elementary School, is the newest school in the district. It is located in Mehlville and opened in 2017, though the building where it is housed opened back in the 19th century as St. John's School, and would later become the first building to house Mehlville High School. MOSAIC is an acronym for Mehlville and Oakville Students Achieve, Imagine and Create. The school offers "a unique learning experience that allows for increased student choice and personalized learning." The district provides bus transportation from each of the other elementaries to MOSAIC after the busses drop off the students at the schools. Due to this, it is the latest-starting school in the district. The school has a student population of around 250, making it by far the smallest "elementary school" in the district. Students come from all over the district, and because the school has no bus routes, it has no set middle school that MOSAIC feeds into. Students and their parents effectively get to choose which middle school they want to go to, based on where they live in the district and/or based on personal choice.

Middle schools
Middle schools in the Mehlville R-9 School District teach kids from 6th grade (11-12 y/o) to 8th grade (13-14 y/o).

The middle schools also host Academy, a personalized learning program based on STEM/STEAM principles. Academy is primarily designed for students who went through the MOSAIC program at Mosaic Elementary.

Bernard is the newest middle school in the district, opening in 2003. It is located in North Oakville on the same property that once was home to Bernard Elementary School.
