Investing in Relational Capital
Iswari Natarajan, High School Principal

St. Mary’s Academy High School excels at preparing young women for leadership in a global society. Our goal is to empower our students through the development of analytical skills, confidence, and generosity to make a difference in the world around them.

As a rigorous college-preparatory school, our seminar-style classes encourage inquiry, debate, and cooperative learning. Our unique Block System schedule consists of four ninety-minute class periods. This proven approach to learning fully engages and focuses your daughter while allowing her to enjoy a fresh slate of classes come January.

Walking through the halls of the high school, you will immediately notice a dramatically different atmosphere – one where girls take center stage. Our students are challenged by their peers to achieve more; they feel more comfortable being themselves and expressing their ideas; and they show greater gains on core academic and life skills.

Our High School students typically push themselves beyond expectations—enrolling in several Advanced Placement classes and taking more than the required number of course credits.

Expect the best from a girl…that’s what you’ll get.

New Research Released December, 2018:
Girls' School Graduates Have a Clear Edge Over Co-educated Peers

Fostering Academic and Social Engagement:
An Investigation into the Effects of All-Girls Education in the Transition to University.  

Prepared by Dr. Tiffani Riggers-Piehl in collaboration with the Higher Education Research Institute (HERI) at the University of California, Los Angeles, this data analysis is an update of the 2009 report commissioned by NCGS and conducted by Dr. Linda Sax and colleagues, including Dr. Riggers-Piehl. 

Fostering Academic and Social Engagement focuses a lens on how graduates of all-girls schools today compare to female graduates of coed schools in terms of their academic characteristics and readiness for university. The findings are extensive and speak highly of the work happening in our schools -- work that is setting up girls' school graduates to be confident and impactful twenty-first century community members, change-makers, and leaders. In summary, the researchers concluded that when compared to their female peers at coed schools, girls' school graduates:

  • Have stronger academic skills
  • Are more academically engaged
  • Demonstrate higher science self-confidence
  • Display higher levels of cultural competency
  • Express stronger community involvement
  • Exhibit increased political engagement
