School Notes

  • Assumption Parish School is a Catholic, Christ-centered learning institution for students in Grades K through 8. We are dedicated to the education of the whole child through the spiritual and the academic growth of our students. We are Catholic inside & out. Catholic values are built-in to all areas of our curriculum. We are focused on the mission of Jesus and our call to evangelize. Our teachers believe that the classroom environment is an important tool for helping children learn. Room arrangements and daily schedules,while carefully designed, are flexible. Student work is on display everywhere, signaling to students that the room belongs to them. There are tables for children to work together in groups and individual spaces for independent work.
