Original Research by School Decision on Thomas L Marsalis El Steam Academy
Thomas L Marsalis El STEAM Academy is a public elementary school in south Dallas serving pre-K through fifth grade, housed on a single campus with a student body that reflects the neighborhood. The school has an enrollment of about four hundred students, with the vast majority from low-income households. The student population is predominantly Black, with a substantial Hispanic enrollment and very small numbers of other groups represented.
The school carries a STEAM designation in its name, indicating an emphasis on science, technology, engineering, arts, and mathematics. However, the available data does not detail what that commitment looks like in daily practice, curriculum emphasis, or course offerings beyond standard elementary instruction, so a parent interested in the specifics of the STEAM program may want to contact the school directly.
Academic performance in 2024-25 shows uneven results across subjects and grades. In English language arts, proficiency breaks down by grade and language: third graders in English showed about half of tested students at proficient or above, fifth graders showed stronger results, while a small Spanish-language testing cohort in fourth grade also showed about half meeting standards. Math proficiency trended downward with grade level, starting at about half in third grade, dropping to just under half in fourth grade, and falling to about forty-five percent in fifth grade. Science showed a steeper challenge, with only about thirty percent of fifth graders meeting proficiency in that subject. Across all subjects measured, roughly four in five students reached the "approaches" level, about half met the standard, and about one in five achieved mastery. Science mastery rates were notably lower.
The overall proficiency index positions this school in the top quartile among Dallas County school districts, meaning its aggregated test results rank above the median performance across the county. That standing reflects relative strength in the county context, though raw proficiency rates themselves point to areas where many students fall below grade-level expectations, particularly in science and in the upper elementary grades.
The school sits in Dallas, a large North Texas city with significant economic diversity by neighborhood. South Dallas, where Marsalis is located, is undergoing substantial development with major employers including Methodist Hospitals, the VA North Texas health system, Amazon, and Frito-Lay/PepsiCo. The area includes newer mixed-use projects such as the University Hills development near UNT Dallas, bringing housing and commercial growth. Housing values in the zip code are moderate and declining modestly year-over-year; rents are similarly modest and down slightly. The affordability metrics suggest that renting costs less relative to income than the national benchmark, making this an accessible neighborhood economically, though the typical household would find mortgage costs a heavier burden.
Dallas Independent School District, which operates this school, approved a historic bond in May 2026 intended to replace aging school buildings, eliminate temporary classroom structures, and upgrade facilities. That project unfolds over the next several years and may eventually bring facility improvements to schools in the district, though Marsalis is not specifically named as a planned replacement. The district also recently broadened access to advanced coursework by shifting from opt-in to automatic enrollment for students who score well on state exams, and adopted a new mathematics curriculum with reduced emphasis on test preparation.
The school is a traditional neighborhood elementary, not selective-enrollment, meaning students attend based on residence. It serves an economically vulnerable student population and has not reported special-education or English-learner enrollment rates, so specifics on those support populations are not available. A parent considering this school would want to visit, talk with current families, and ask directly about the STEAM program's implementation, special services availability, and whether the school's current proficiency levels and grade-level trend match their child's needs and your expectations for what elementary school should provide.
