The present population is 1,355 students and includes students from thirty-nine Elementary Schools. St. Thomas has a Code of Conduct developed collaboratively by staff, and parents, which ensures a student's right to be educated in a caring, respectful environment. St. Thomas has an Honour Society in order to grant recognition to their top students.

The board's plan integrated the student populations from both high schools, with as little student displacement as possible.[3]
