Welcome to The Montessori School of San Antonio
Where children are guided to be passionate learners, independent thinkers, and engaged citizens.
The Montessori School of San Antonio was founded as the Judson School – a Montessori Workshop in 1974. From there it has grown to include Primary, Elementary, and Middle School Montessori programs. The MSSA campus is a secure 24-acre parcel at the intersection of Loop 1604 and Rogers Ranch Parkway in far North-Central San Antonio with a surrounding environment designed specifically to meet the learning criteria set out by Dr. Maria Montessori.
As a parent, I can confidently say that I could not have chosen a better community for my children and our family unit. MSSA works hard to maintain a wonderful learning environment where grace and courtesy are always paramount. The education is challenging, yet manageable, and it allows students to have a very subtle transition when moving on to a higher grade-level."
Academics at MSSA
With an active and experiential learning environment, the academic program at The Montessori School of San Antonio lays the foundation for children to become lifelong learners. Smaller class sizes allow for accommodating individual students and their personal learning styles. MSSA values all student’s unique strengths and guides them to become strong community members.

🌕✨ What a wonderful celebration of culture in two of our classrooms today! The family of a Primary student and a Lower Elementary student shared the story of Chuseok, Korea’s traditional harvest festival, with their classmates.
Dressed beautifully in hanbok, they explained the significance of honoring ancestors, sharing delicious foods like songpyeon, and celebrating family and gratitude. 🍂🎉
Their presentations are a reminder of how fun and meaningful it is to learn from each other’s traditions. #mssa #themontessorischoolofsanantonio #montessorischool

💙The Montessori Racks and Tubes is an essential material in Lower and Upper elementary classrooms that brings long division to life.
💚Students "build" large numbers with the beads that physically represent the number to be divided. They set up the correct number of skittles for the divisor and use the boards to distribute beads among groups, mimicking the process of sharing or dividing. Students work step-by-step: divide, multiply, subtract, and bring down, just like on paper, but with every stage made concrete and visual.
💙This material allows children to see, touch, and truly understand what happens during division and lays a deep mathematical foundation for students as they move into higher-order mathematical thinking. #mssa #themontessorischoolofsanantonio #montessorischool #montessorimaterials

🔧Practical life skills are woven into every level at MSSA. On Friday, two Upper Elementary students joined Coach O to help with some shelving. After a quick start from Coach O, the students took over by assembling the unit, moving it to the gym, and organizing the shelf materials. Later, a Lower Elementary student discovered tranquility with the items on the shelf and the gym’s new Peace Corner. #mssa #themontessorischoolofsanantonio #practicallifeskills #montessorischool
