Don T Durham Int, Southlake TX - Test Scores & Data

Original Research by School Decision on Don T Durham Int

Don T Durham Intermediate School serves grades five and six in Southlake, a prosperous suburb in the Dallas-Fort Worth area. The school sits within Carroll Independent School District, an affluent suburban district whose enrollment has been declining for years.

The school's academic profile is strong. In mathematics, the vast majority of fifth and sixth graders performed at or above proficiency. Sixth grade math performance was especially high, with proficiency well above the fifth grade level. English language arts was also solid, with nearly all fifth graders and the overwhelming majority of sixth graders meeting proficiency. Science showed more range: fifth grade science performance was lower than the other tested subjects, trailing math and reading by a meaningful margin, though still at a majority-proficient level. State testing data at this school were available only for grades five through six; the school also serves students who are tested at higher grade levels through the intermediate structure, though those results appear in this data set under different grade designations reflecting state testing tiers rather than campus grade spans.

The school's peer group is affluent and highly educated. The enrollment skews toward white and Asian students, with smaller shares of Hispanic and Black enrollment. Free and reduced price lunch data were not available for this school.

Southlake itself is an upscale, car-dependent residential suburb built around Southlake Town Square, a mixed-use downtown center. The area attracts affluent, highly educated families. Home values in the zip code are well above state and national medians. Median household income is high, and most adults hold bachelor's degrees or higher. The broader Tarrant County area is economically stable with moderate unemployment.

Carroll ISD faces structural enrollment decline. The district board voted in late 2025 to close Durham Intermediate School effective the 2027-28 school year, consolidating the district's intermediate and middle grade structure from three campuses to two. This is a significant change that will affect school assignments and attendance boundaries for families with children in those grades. Parents with elementary or middle-grade students may want to confirm with the district how this closure will affect their own family's campus assignments.

The district's property tax rate has fallen substantially over recent years, lowering the financial cost of home ownership despite high values. In November 2025, voters approved an additional three-cent increase to the maintenance-and-operations tax rate, projected to bring several million dollars in new annual revenue for staff compensation and programs.

The district's recent history includes prolonged conflict over diversity and cultural competence initiatives. A proposed Cultural Competence Action Plan was formally rejected in December 2021 as part of a lawsuit settlement, and the district's diversity council was disbanded. Federal civil rights investigations were opened into the district during this period. These events shaped the district's pedagogical direction; families should be aware that proposals around diversity, equity, and bullying programs were rejected and remain contested.

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.
