St Michael’s Stanmore has six classes from Kindergarten to Years 5/6. Year 6 students assume special responsibilities as the senior students in the school. 

There is an active and enthusiastic Student Council with representatives from Years 2 to 6 including two School Captains in Year 6.

Students working in conjunction with the school's Religious Education Co-ordinator, have the opportunity to participate in the Mercy In Action Group (MIAG). These students lead the school in being merciful towards their peers and the wider community. These students follow the example set by Catherine McAuley and the Sisters of Mercy to help their peers show mercy to all in our community.
