School Notes
- Children can make an impact on the world right now. That's what St. Mary's School is all about. We teach students to ask "what" and "why," demonstrating that they are an essential piece of the answer to "how." Because when students are guided by compassion and critical thinking, they take responsibility for the world without hesitation.
- St. Mary's offers the only accredited Preschool through Grade 8 International Baccalaureate Programme in Orange County. This curriculum integrates themes of global significance, challenging students to tap their creativity to solve problems both large and small. More importantly, teaching the power of inquiry and reflection to young minds builds a foundation for lifelong learning. Applying a curriculum free to change alongside the world, the International Baccalaureate Programme prepares St. Mary's School students to thrive across an increasingly connected globe.
- St. Mary's School's academics, curricula, and environment prepares students to believe in themselves, trust their ideas, and achieve.
- But experience, confidence, and skill aren't enough. Critical thinking depends on a solid base of values and vice versa.
- Every day, students encounter complex situations that require them to test the truth of the information in front of them. What's more, they have to do this compassionately, with respect for the diverse perspectives of their peers. This is no easy feat, but it's essential.
- Inquiry without love is as much of a dead-end as compassion without intelligence. That's why, at St. Mary's School, we foster academic excellence and empathy in tandem. Regardless of background, we help students invest in their own drive to make a difference.
- A snapshot of St. Mary's School from any angle, on any day, captures the school's unique blend of visible engagement, compassionate inclusion, and genuine delight. From preschool age on, we teach students to say, "I can."

School Reviews

This is school is a wonderful place to send your child for a private education. The teachers are so kind and really pay attention to the students needs. St. Mary's is truly home.
5 11/9/2017
St Marys has been our "home" for the past 17 years!! Both my boys started attending when they were 2 years old. This being our last year (my youngest is in 8th grade) I wanted to write a review of our wonderful school so other families can benefit from this great institution. My children were surrounded by a caring community! The IB program is phenomenal. Teaching children to be global citizens, with the IB profiles. IB learners learn to be: Inquirers, Knowledgeable, thinkers, communicators, principled, open-minded, caring, risk-takers, balanced & reflective. The transition into high school for my oldest was seamless. He has thrived & will be graduating high school this year. I cant say enough wonderful things about St Marys. It would be wonderful if any family could provide such an education for their student!!
Endorse St. Mary's School. Endorsements should be a few sentences in length. Please include any comments on:

- Availability of music, art, sports and other extracurricular activities
