Summary

Cardiff J H is a middle school in Katy, TX, serving 803 students in grades 6-8 as part of the highly-rated Katy Independent School District (Isd), and it stands out for its exceptional advanced math program and strong support for specific student groups despite serving a community where over 82% of students qualify for free or reduced lunch.

Cardiff’s biggest strength is its Algebra I program, which consistently achieves proficiency rates above 84%—far exceeding the district and state averages. For example, in the 2025-2026 school year, 95.77% of Cardiff students passed Algebra I, compared to 77.31% for the district and 54.03% statewide. This suggests a highly effective system for identifying and accelerating students into advanced math. However, the school faces a challenge in standard grade-level math, where only about 25% of 7th graders are proficient, creating a "two schools in one" dynamic. Cardiff also excels with specific subgroups: Gifted and Talented students rank in the 82nd percentile, English Language Learners in the 75th percentile, and low-income students in the 69th percentile. Additionally, the school maintains a low student-teacher ratio of 11.2, which is significantly lower than nearby schools like Stockdick J H (13.8) and Rowe Middle (17.0), allowing for more individualized attention.

Compared to neighboring schools in the Cypress-Fairbanks Independent School District (Isd), Cardiff outperforms them in most metrics, including 8th-grade reading proficiency (55.69% vs. 44-50% for CFISD schools). However, a persistent weakness is 8th-grade social studies, where scores (27.34%) fall below the state average (31.69%) and well below the district average (55.06%). An interesting contrast is Calvin Nelms Middle, a small charter school nearby that achieves higher overall test scores but with a much higher student-teacher ratio (21.0) and lower spending per student ($8,012 vs. Cardiff's $11,739). Overall, Cardiff is a school of contrasts: it excels at accelerating select students in math and supporting diverse learners, but it must work to raise achievement for the majority in standard math and social studies.
