Summary:
In zip code 75214, there is one middle school, J L Long Middle, serving grades 6 through 8 with an enrollment of 1,079 students as part of the Dallas Independent School District (Isd).
J L Long Middle shows a clear strength in advanced mathematics, with 88.27% of 8th graders in the Algebra I End-of-Course exam achieving proficiency in the 2025-2026 school year—far exceeding the state average of 54.03%. However, this success contrasts sharply with standard 8th-grade math, where only 32.42% of students were proficient, well below the state average of 47.24%. The school performs consistently above the district average in reading across all grade levels, with proficiency rates around 55-56%, and also outperforms the state in 8th-grade social studies (38.44% vs. 31.69%). The school’s state ranking has improved for three consecutive years, rising from the 46th percentile in 2023-2024 to the 59th percentile in 2025-2026, and its dropout rate of 1.9% is nearly half the district average of 3.2%.
For parents, the key takeaway is that J L Long Middle offers a strong advanced math track for high-achieving students, but the majority of 8th graders struggle with standard math and science compared to state averages. The school is on a positive upward trend overall, with improving rankings and solid reading performance, making it a competitive option within the Dallas ISD. With 63.67% of students economically disadvantaged and a student-teacher ratio of 16.3:1, the school serves a diverse population while maintaining a lower dropout rate than the district.
