Founded in 1962 with 29 girls as its first students, St Agnes Catholic High School has catered for students in Year 7 to 10 in the Rooty Hill community for over 50 years.
Established by the Franciscan Missionaries of Mary, the school upholds the Franciscan spirit of simplicity and acceptance of all. In 1976 the school was handed over to the Sydney Diocese. As needs and wishes of the local people grew St Agnes High School become co-educational in the 1979 school year. From 1999 to 2004 it was incorporated into a multi-campus college, Christ Catholic College. In 2004 this was disbanded and St Agnes Catholic High School again operated independently, providing education for young people in the greater Mount Druitt area.
Students first attended lessons in the original buildings, then, with increases in the student population, new buildings were developed. The original homestead has been carefully preserved and extended. It now houses the administration offices and staff facilities of the school.
St Agnes Catholic High School, as it is now known, provides a quality education for students from Years 7 to 12 while maintaining the Franciscan spirit of simplicity, acceptance of all and a deep personal love of Jesus. Indeed, the handing on of the values has a very important part in the life of the students. The strength of the school lies in the students, in their openness, the joy they have of life, their friendliness and their optimism.
