The top reported proficiency rate is 28% in Math. The lowest is 26% in Science.
Original Research by School Decision on St. Clair Jr. High
St. Clair Jr. High serves students in sixth through eighth grade as part of the St. Clair R-XIII district in Franklin County. It is a regular public school with a middle‑school population that is predominantly white, and a substantial share of students qualify for free or reduced‑price meals. The school is the only junior high in a small, four‑school district that sits on the I‑44 corridor roughly halfway between St. Louis and the rest of the Ozarks. For a parent, the central fact is what the state assessments show: proficiency rates across math, English language arts, and science are low, and the school places in the bottom quarter of districts in Franklin County when overall academic performance is measured. That position is based on the mean of all reported grade‑level and subject results.
The Missouri Assessment Program data for the 2024‑25 school year paints a consistent picture. In sixth‑grade math, about one in five students scored at the proficient or advanced level, while in seventh‑grade math that share rose to roughly one in three. Eighth‑grade math results were suppressed, so no reliable figure is available for that grade. English language arts results follow a similar pattern: roughly one in five sixth graders and one in five seventh graders tested proficient, while eighth graders performed better, with nearly half reaching that bar. Eighth‑grade science proficiency landed at about one in four. These numbers make clear that meeting state standards is a challenge for a majority of students in most tested grades and subjects. The eighth‑grade ELA result stands out as the highest single percentage, but overall the school’s academic profile is soft. Because no data on chronic absenteeism, discipline, or staffing were available, a parent might want to ask about those areas directly with the school.
The student body is moderate in size for a middle school, with roughly equal enrollment across the three grades. The demographic makeup is heavily white, with only small numbers of other racial or ethnic groups. Information on students with disabilities and English learners was not provided. The school does not have a magnet or charter designation, and its Title I status was not reported.
St. Clair itself is a small city that describes itself as a rural bedroom community of the St. Louis metro area. After a major manufacturer closed years ago, the workforce shifted toward commuting along I‑44. The city still hosts a number of manufacturing, engineering, and banking employers, and the district is one of the larger employers in town. Housing values in the zip code fall below both the state and national benchmarks, and the local market has seen modest price growth recently. The city has been roughly flat in population, though it actively promotes economic development with tax incentives and has several tracts of land zoned commercial at the highway intersection. The built environment is oriented around highways rather than walkable streets, and there is no public transit system documented. The district itself has no recent parent‑relevant changes on record—no bond issues, no curriculum overhauls—so the school environment has been stable in that sense.
St. Clair Jr. High is the kind of school where a family can expect a typical middle school experience in a small‑town setting, but where state test results suggest that the overall academic bar is not being met by most students. The school’s strengths are not evident in the available data; there are no advanced course offerings, no specialized programs, and no extracurriculars listed to offset the achievement picture. For a parent weighing options, the question is whether the low proficiency rates reflect the school’s instructional approach, student readiness coming in, or community conditions—and whether the school has plans to address them. The district’s absence of recent visible changes could mean stability or a lack of new initiatives; that is worth clarifying with administrators. A family that prioritizes strong academic outcomes on state measures will want to dig deeper. A family already rooted in the community may find the school familiar and accessible, but should ask pointed questions about how the school supports students who are not yet at grade level.
