Seabourn El, Mesquite TX - Test Scores & Data

Original Research by School Decision on Seabourn El

Seabourn Elementary serves pre-K through fifth grade in Mesquite, a suburb in Dallas County. The school enrolls a little over six hundred students, a composition that is predominantly Hispanic with a substantial Black population and smaller shares of white, multiracial, and Asian students. Nearly all students are eligible for free or reduced-price lunch, marking this as a high-poverty school.

State testing results from the most recent year show mixed academic performance across grade levels and subjects. In mathematics, proficiency varies by grade: fourth grade shows the strongest results, while fifth grade and especially third grade trail behind. English language arts results are generally lower across the board, with third grade recording particularly weak performance. Fifth-grade science proficiency is notably low. When looked at school-wide, about half of students across all tested grades meet or exceed proficiency standards in English language arts and mathematics combined, while science proficiency in the tested grade falls well below that threshold.

Math shows relative strength compared to language arts. The school reports that roughly three-quarters of students approach grade-level math standards, and about a quarter demonstrate mastery. For English language arts, two-thirds approach standards while fewer reach mastery. Science at the fifth-grade level shows the softest picture, with less than a third meeting proficiency. Social studies results, also measured only in fifth grade, are similarly low.

When positioned against other districts in Dallas County, Seabourn's overall proficiency index places it in the top quartile, an indication that despite the numerical results, the school's performance ranks above the typical district in the county. This may reflect the county's range; a parent may want to look into how these results compare to schools in their specific attendance zone or comparable demographics.

The school serves a student population facing economic hardship. The high concentration of students on free and reduced-price lunch indicates that many families experience financial stress. The neighborhood housing market shows moderate values with rents well below ownership costs, suggesting that many families rent rather than own. One data note: the school does not provide counts for students receiving special education services or identified as English learners, so the full picture of academic support needs is not visible here.

For families considering this school, the key takeaway is a community with substantial learning needs, strong math foundations relative to language arts, and a peer environment that reflects south Dallas County's demographic and economic character.

Graduation rate (ACGR) reflects the federally published Adjusted Cohort Graduation Rate for the most recent year available. We refresh this data annually at the close of each academic year in June. The federal source publishes a banded rate (for example, "90-94%") instead of an exact number for cohorts small enough to risk identifying individual students. The state distribution chart, where shown, plots every school in the state with a published rate or band; schools whose rate is federally suppressed are excluded. Where the federal source publishes a band rather than an exact rate, the school is placed within its band using a stable, ID-derived offset, so its position is consistent across visits.
