St. Thomas School provides early childhood, pre-primary, and primary education for students from 2 ½ years of age through to the eighth grade.

The public facades of the school are designed to reflect the more formal, rectangular, stone-clad character of the adjacent church.

The facility was designed to celebrate cycles of nature and human learning, to demonstrate leadership in environmental responsibility, and to support the school's educational program by addressing the latest research on cognitive development.

The grounds include a playfield, covered play areas, and a children's garden for students to cultivate plants.

St. Thomas' Center for Leadership and Innovation is completing new offices and work space on campus that should be finished in 2022.
