Summary:
Zip code 75135 in Caddo Mills, Texas, is served by two middle-grade schools within the highly-rated Caddo Mills Independent School District (Isd), which together form a continuous pipeline for students in grades 5 through 8 with a combined enrollment of approximately 939 students.
The standout school in this area is Caddo Mills Middle, which serves grades 7 and 8 and excels in advanced academics. Its most impressive achievement is in Algebra I, where 92.13% of 8th graders taking the high-school-level exam were proficient in 2024-2025—nearly double the district average and far exceeding the state average of 47.01%. The school also boasts strong 8th-grade reading scores (72.25% proficient vs. 56.39% statewide) and a zero dropout rate. Meanwhile, Caddo Mills Intermediate, serving grades 5 and 6, provides a consistent, above-average foundation, particularly in 5th-grade science (36.48% proficient vs. 29.57% statewide) and math across both grades. This strong preparatory work directly feeds into the middle school's success in advanced math.
A key takeaway is the "feeder pattern" strength: the intermediate school builds a solid base, enabling the middle school to achieve elite results in Algebra I. However, this creates a notable weakness in 8th-grade math, where only 35.51% of students were proficient—well below the state average of 44.81%—likely because top performers are taking Algebra I. Social studies is also an area for growth at the middle school, despite outperforming the state. Overall, the intermediate school offers balanced, consistent performance, while the middle school delivers exceptional peaks in specific subjects, making the area a strong choice for families seeking a rigorous academic pipeline, particularly in math and reading.
