OUR SCHOOL MOTTO & STRATEGY
Our school focuses on teaching students in a way that helps them develop their fullest potential. We use a unique approach called the KASSM method, which encourages students to learn in new ways. By combining academic learning with other activities, we help students become well-rounded individuals. Our goal is to create a learning environment where students can grow and develop in all areas of life.
Why St. Mary's High School Stands Out Among the Best Schools in Dahisar
At St. Mary’s High School, we focus on more than completing the syllabus. We work to create a learning environment where students can build knowledge, confidence, creativity, and strong values. Our approach has helped us earn the trust of families looking for best schools in Dahisar.
Consistent Academic Performance
Our SSC Roll of Honour reflects steady academic performance over the years. Between 2018 and 2022, our students achieved strong results across different academic batches.
- Ms. Dubey Aarya Alok – 94.2% in 2018
- Mst. Jain Divyansh – 95.4% in 2021
- Ms. Shenoy Shruthi – 95.4% in 2021
- Mst. Singh Harsh – 94.6% in 2022
These results show that academic achievement is not limited to a single year. We continue to support students with structured learning and guidance throughout their school journey.
Learning Beyond Rote Education
We encourage students to understand concepts, ask questions, and think independently. Our teaching approach gives importance to critical thinking and creativity alongside academic learning.
For families comparing schools in Dahisar, this student-focused approach can make an important difference. We want children to understand what they learn and apply their knowledge with confidence.
Teachers Who Guide and Mentor
Our experienced faculty members do more than deliver lessons. We aim to create a supportive classroom where teachers can teach, motivate, and mentor students. Regular guidance helps students recognize their strengths and work on areas where they need support. This personal attention adds value to the academic experience we provide.
A Balanced Co-Curricular Calendar
We believe students need opportunities to learn outside the classroom as well. Our annual calendar includes activities related to science, culture, national days, environmental awareness, and physical education. These activities encourage participation, teamwork, discipline, and confidence. They also support the all-round development that parents expect from best schools in Dahisar and Borivali.
Facilities at St. Mary's High School, Dahisar East
We believe a good learning environment needs more than a strong academic programme. Our facilities are planned to support classroom learning, physical activity, safety, and regular communication with parents.
Comfortable Classrooms
Our classrooms are spacious and well ventilated. They provide students with a comfortable setting for daily lessons and classroom activities.
Science and Computer Labs
Our Science and Computer Labs are equipped with modern resources for practical and technology-based learning. Safety measures are followed, and skilled lab assistants support students during laboratory activities.
Library for Wider Learning
Our well-stocked library gives students access to reference books, fiction, and subject-related resources. It encourages reading and helps children explore topics beyond their regular syllabus.
Outdoor Play and Physical Education
We provide an outdoor play area for regular physical activities. Students take part in Sports Day, fitness activities, and team-based games that encourage discipline and teamwork.
Safe School Transport
Our school buses are GPS tracked and operated by trained, professional drivers. We provide door-to-door transport services across Dahisar East and surrounding areas, helping make daily travel more convenient for families.
Campus Safety and Hygiene
We have CCTV surveillance across all floors of the campus. This helps us monitor the premises from student arrival through departure.
We also maintain sanitised premises and provide safe, clean drinking water throughout the academic year. These measures support a healthy school environment for every child.
Easy Parent Communication
Our Xavier's Parent App is available on both iOS and Android. Parents can receive real-time updates about timetables, events, and school communication directly on their phones.
These facilities support the complete school experience we aim to provide for families considering schools in Dahisar. They also strengthen our commitment to creating a safe, comfortable, and engaging environment expected from the best schools in Dahisar.
