School Notes

  • The School of St. Mary's primarily emphasizes spiritual education and development as concisely articulated in the Gospel of Jesus Christ.
  • Academically, students excel in high school. Students consistently are placed in high level academic tracks. Many students choose to continue their Latin studies, which begins in fourth grade. We offer a STEAM (Science, Technology, Engineering, Art, Math) class in our new state-of-art lab as part of students` everyday curriculum at the Upper Grade Center. Robotics; design and mechanics are important, real-world skills our students grasp early-on that lead to academic interest in high school, college and beyond.
  • Most importantly, School of St. Mary students reap the benefits of a strong Catholic education. Weekly Mass, preparation for the sacraments and daily religion class combine to give students strong faith foundation.
  • The School of St. Mary`s balanced approach to education is the best of both worlds. A stellar academic program coupled with a strong foundation of faith has proven to be a successful model for over one hundred years.  We look forward to continued growth and excellence in the next one hundred years.
