Holy Trinity's K-6 Department has a population of around 300 students. Students are part of a warm and supportive community where teachers know their students and students feel that they belong. The Department is made up of Infants (K-2) and Primary (Years 3-6). Students have their own class block and playground areas. This helps students and staff to build strong relationships. There are times throughout the week and year where all students come together to foster a sense of community.
