Mill Street Elementary

Mill Street Elementary is a PK-5 school in the Lewisville Independent School District (Isd) serving 665 students in a densely populated area of Lewisville, where over 83% of students qualify for free or reduced-price lunch. The school has faced significant academic challenges, with state rankings consistently in the bottom 5% of Texas elementary schools for the past five years and test scores across all subjects and grade levels dramatically lower than district and state averages—often by 20 to 40 percentage points. For example, only 11.76% of 5th graders were proficient in Math compared to 54.73% district-wide, and proficiency rates in Reading and Math are roughly half of the district average.

Mill Street spends $11,463 per student, which is higher than several nearby schools with better outcomes, such as Marjory Vickery Elementary ($10,648) and Southridge Elementary ($11,422), suggesting the challenge is not a lack of funding but rather a need for more effective resource allocation. Nearby schools like Creekside Elementary (71st percentile) and Degan Elementary (43rd percentile) perform at significantly higher levels. Interestingly, Central Elementary, located just 0.33 miles away, shares a similar demographic profile with an even higher free/reduced lunch rate of 95.11% and also ranks in the bottom 10% of the state, indicating systemic challenges in this area of Lewisville.

There is a glimmer of hope: the 2025-2026 school year saw a slight improvement in the school’s overall rank (3rd percentile) compared to the previous year (1st percentile), breaking a multi-year pattern of decline. Performance for African American students (23rd percentile) and Special Education students (14th percentile) also showed notable improvement, suggesting targeted interventions may be starting to work. The school’s performance for its core demographic of low socioeconomic status students remains in the bottom 2% of the state, highlighting the critical need for intensive, evidence-based interventions focused on early literacy and numeracy, as well as comprehensive support systems to address non-academic barriers to learning.
