School Life

To enrich their school life and create lasting skills, friendships, and memories, our students are encouraged to participate in the activities, clubs, and co-curriculars we offer. Our Prefect system offers student leadership opportunities, and the tradition of the House system is a vital and integral part of life at SMLS. The school fosters a sense of caring and responsibility by encouraging community involvement with class projects and fundraisers. There is so much for students to benefit from beyond the classroom.  

SMLS Alumnae

Girls who attend SMLS enjoy lifelong friendships with their fellow students, and are welcome back to their school anytime! We have a strong Alumnae Association of empowered women who can be found living and working across the globe. A number of our alumnae have sent their daughters to the school, constituting second and third generation Millies - a testament to our exceptional educational experience. Once a Millie, always a Millie!

SMLS is a registered charity, and as such, we rely on the generous donations of our constituents to provide our students and faculty with the resources they need to learn and grow.
