Summary:
The Midlothian Independent School District (Isd) is home to three middle schools—Walnut Grove Middle, Earl & Marthalu Dieterich Middle, and Frank Seale Middle—serving grades 6 through 8 in a highly ranked Texas district (85th percentile statewide).
Walnut Grove Middle leads the district as the top performer, ranking in the 87th percentile for the 2025-2026 school year with the strongest reading and math scores and the lowest percentage of students receiving free or reduced lunch (16.3%). Earl & Marthalu Dieterich Middle is a close second, ranking in the 83rd percentile and excelling in advanced coursework with a 96.12% Algebra I proficiency rate and a 0.0% dropout rate. In contrast, Frank Seale Middle ranks lower at the 47th percentile, with the highest percentage of economically disadvantaged students (53.31%) and the highest spending per student ($10,468), yet it still achieves strong Algebra I results (94.74% proficiency).
A key takeaway is the "Algebra I Paradox": all three schools perform exceptionally well in Algebra I despite wide gaps in other subjects, suggesting this course serves a select group of advanced students. Another notable finding is that 7th grade math is a district-wide challenge, with proficiency rates falling below the state average across all schools. While Walnut Grove Middle shows an upward trend in rankings, Frank Seale Middle has remained stagnant, highlighting the impact of socioeconomic factors on overall performance. For parents, Walnut Grove Middle offers the strongest all-around academics, while Earl & Marthalu Dieterich Middle provides excellent advanced coursework opportunities.
