All Girls High School

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.

BE HERE, BE YOU, BELONG!

Fear of the unknown can often hold us captive. In the face of fear, when we choose to enter the arena, place one foot in front of the other, and pivot if we need to, that's when we grow. That's when we spread our wings and soar! This new academic year is calling all of us to do just that - to show up in the face of uncertainty with courage, flexibility, grace, and compassion. I start every academic year with a town meeting at Snow Mountain Ranch with our students. The entire high school student body huddled close together with the beautiful backdrop of our Rocky Mountains is the perfect setting to come together as a community. I have often felt that I wouldn't have it any other way, but this year was different. I  ZOOMed in from my HS office into the Swivl units in every classroom (a sentence I never imagined I would say). We were all masked up and physically distanced. It couldn't be further away from our usual setting, but it was pure magic. Even though we were six feet apart, we were together at heart like never before. The feeling of community was palpable. I would like to share the two "calls to action" that I shared with the students:

  • Mask up, stay 6' apart, and protect our community: This first week made us all realize how much we have missed being together. Staying open during these times and having school in-person is a privilege that is not lost on any of us. So, we collectively promised to do our part to protect our community.

  • Shed the inner mask you wear, be you, and belong: To navigate high school, often, students wear an inner mask, project an image to fit in, and conceal their inner self. Fitting in is about how others perceive us and what they think of our actions. Belonging comes when we are real and authentic. Choose to belong instead of fitting in. Always. So, we decided to each take one step to shed our inner mask, be unapologetically ourselves, and belong.

I am often caught bragging about our SMirls like a proud mama, but this year, more than ever,  my heart is overflowing with pride as we start the new year that promises to be full of confounding challenges and extraordinary opportunities. I invite you all to be here, be you, and belong!

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
