Summary

Cardiff J H is a public middle school located in Katy, Texas, serving grades 6-8 with a total enrollment of 818 students. It is part of the Katy Independent School District (ISD), which is ranked 172 out of 961 districts in Texas and has a 4-star rating from SchoolDigger.

Overall, Cardiff J H faces challenges in improving academic performance, particularly in core subject areas like Reading and Mathematics, where the school lags behind district and state averages. The school's test scores are generally lower than the Katy ISD and Texas state averages across various STAAR assessments. Additionally, the school's performance varies significantly across different student subgroups, indicating a need to address the unique needs of underperforming subgroups, such as English Language Learners and At-Risk students. However, Cardiff J H's strong performance in the Gifted and Talented student subgroup suggests that the school may have a robust program for high-achieving students, which could be a potential area of focus and strength.

Comparing Cardiff J H to nearby schools, such as Rowe Middle, Kahla Middle, and Stockdick J H in the Cypress-Fairbanks ISD, as well as Calvin Nelms Middle, a public charter school, provides valuable insights into areas for improvement and potential best practices that could be adopted. These comparisons suggest that Cardiff J H has room for growth in order to better serve its diverse student population and improve overall academic outcomes.
