Mumford Independent School District (Isd)

The Mumford Independent School District (Isd) is a small, high-performing district in Texas consisting of just two schools—Mumford Elementary (serving grades PK-6) and Mumford High School (serving grades 7-12)—that together serve 598 students and rank in the top 2% of all Texas districts.

Both schools are standout performers, but they excel in different ways. Mumford High School is the district’s crown jewel, ranked 43rd out of 2,009 high schools in Texas (98th percentile) with a 100% proficiency rate on the English II Reading EOC exam, a 0.0% dropout rate, and a 97.6% graduation rate. Mumford Elementary is a powerhouse in its own right, ranked 339th out of 4,627 elementary schools (93rd percentile), with all grade levels scoring above 76% proficiency in Reading and 4th and 5th graders achieving over 90% proficiency. The high school spends nearly 30% more per student ($9,118 vs. $7,055) and has a much lower student-teacher ratio (11.7:1 vs. 17.2:1), reflecting the higher costs of specialized courses and individualized attention for older students.

The most striking finding is that both schools achieve top-tier results despite over two-thirds of students being economically disadvantaged, suggesting highly effective teaching and support systems. Math is a relative weakness—elementary math proficiency ranges from 58% to 75%, and 8th-grade math dips to 57%—but still far exceeds the state average. The data reveals a seamless academic pipeline: 6th graders score 76% in Reading, and by high school they achieve 100% on English II. Both schools have maintained top rankings for three consecutive years, demonstrating a sustainable culture of excellence rather than a temporary spike.
