The school has been built in five stages. The first two stages being architecturally designed by H.A.Browne, and all other stages by G. & M. Consultants. The final building stage was completed in 1998, with provision for 600 students from Preschool to Year 7.
A refurbishment of the Administration Centre is planned for late 2016.
The community developed the school logo and motto of "Knowledge, Truth, and Love" in 1992. This gave the school clear direction and vision for their mission. A mission statement was formulated in 1994. It emphasises a basis of Christian values within a caring community, which nurtures the potential and uniqueness of each individual. The current Mission and Vision statement have been reviewed and renewed to reflect contemporary pedagogy and Catholic identity for 21st Century. St Rita’s Vision succinctly calls for all in the community to come each day to Know More, Do More and Be More.
