About the school
St. John XXIII College Preparatory is listed as a private school in Katy, Texas, by the Texas Comptroller TEFA participating-school roster.

Its campus address and a current academic-year signal were separately corroborated on the school website.

The school's official website and campus contact details were cross-checked on 2026-10-31. Contact the school directly for current tuition, admissions dates, curriculum and grade availability.
