Staff at a Private Christian School in Singapore

At the core of a private Christian school are the educators and the school staff that nurture and guide the students to their fullest potential.

At TLS Academy, our curriculum adopts a method that promotes independent learning. The focus is on students’ learning rather than teachers’ teaching.

Teachers or educators are referred to as Supervisors, and classrooms are referred to as Learning Centres. A Learning Centre is headed by one Supervisor who is assisted by one or more Monitors (Administrative assistants or teacher aides) or another Supervisor.

Our staff members are chosen based on their individual merits, educational background, life experience and their heart for children and youth.
