Original Research by School Decision on Mark Twain Elem.
Mark Twain Elementary serves kindergarten through fifth grade as a regular public school in the Brentwood School District, a small suburban district in inner-ring St. Louis County. It sits in the city of Brentwood, a densely populated suburb known for a mix of residential neighborhoods and a strong commercial corridor. The school itself is small in overall enrollment, and class sizes are modest enough that state testing data is sometimes suppressed to protect student privacy. For a family looking at this school, the first thing to know is that the student body is relatively affluent, with a modest share of students qualifying for free or reduced-price meals, and it is racially diverse, with a majority white population alongside sizable shares of Asian, Black, and multiracial students.
State assessment results from the 2024-25 Missouri Assessment Program are the primary academic signal available. Across the subjects and grades with reportable data, the school performs well. In fourth grade, a strong majority of students scored proficient or above in both math and English language arts. Fifth grade science results were even higher, with most students meeting proficiency. Third grade math showed a smaller share reaching proficiency, but that result came from a tested group that was small, so a single cohort's performance may vary year to year. Results for third grade English language arts and fifth grade math and English language arts were suppressed due to low tested counts, so no reliable conclusion can be drawn from those groups. Looking at the bigger picture of the school's overall proficiency across all tested subjects and grades, Mark Twain places in the top quarter among districts in St. Louis County. That is a clear strength, and it aligns with what one would expect from a school in a community where housing values and household incomes are above the national median for the metro area.
No graduation rate is available because the school ends at fifth grade. There is no data on chronic absenteeism, discipline, staffing ratios, or course access, so a parent would want to ask the school directly about class sizes, enrichment offerings, and student support services. The district brief found no recent major changes such as bond referendums, boundary shifts, or curriculum overhauls to report, so the broad context appears stable.
Brentwood itself is an inner-ring suburb with a small-town feel despite its density. It is well served by MetroLink light rail and bus transit, and the city maintains parks, an ice rink, a community center, and a public library. Commercial activity is concentrated along Brentwood Boulevard and Manchester Road, including many national retailers. The city's population has been steady in recent years, and housing options range from single-family homes to condominiums and apartments. Home values in the area have softened slightly in the most recent year, but remain in a moderate range for the region, and the rental market is active.
For a family considering Mark Twain Elementary, the picture is of a small, performing elementary school in a stable, amenity-rich suburb. The academic results are strong where data is available, and the student demographics reflect a community with relatively low poverty. The school fits those who value solid state test scores, a manageable school size, and a setting that is suburban but not far from downtown St. Louis. A parent may want to investigate what enrichment programs, special education services, and English learner supports look like in practice, as those details were not provided. But the core academic profile is a favorable one relative to other schools in St. Louis County.
