The All Girls High School Advantage

“Mercy is not a girls school without boys; it's a school where young women can excel in all areas - academics, student government, spiritual life, sports, the arts - and assume the leadership roles in every one of them.” - Mercy Teacher

Mercy High School is all about girls! The top scholars, the school leaders, the class officers, the student-athletes, the peer ministers - all girls! The first students called on in the class, those nominated for awards, the ones receiving the extra support needed to succeed - all girls!

Read what the experts say about the value of an All Girls Academic Environment:

“Single-sex schools are designed to make girls the center of learning, leadership growth and opportunity. Taking leadership positions in high school helps prepare young women for leadership in their adult lives. Colleges and universities are eager to recruit students who have proven they can lead others. In the workplace, leadership is essential for promotion… It is crucial that young women be given as many opportunities as possible to become leaders.”

“At girl's schools, we believe that single-sex education is not merely a matter of separating girls and boys. It's about making sure girls take center stage, while drawing upon all that we know about the way they grow and learn. It's not just the classroom. It's the combination of the community, the culture and the climate girls' schools offer that makes all-girl education such a powerful and transformative experience.”

“…all girls' schools, whether independent or Catholic-affiliated, produce graduates who enter college slightly more academically and politically engaged than women from similar backgrounds who attended coeducational private schools. Additional benefits are found specifically within the Catholic school sector, where attendance at an all-girls' school enhances students' scientific orientation (especially for Latinas), predicts higher SAT scores, and promotes an orientation towards college that is more educationally-motivated and less economically-motivated than is found among female graduates of Catholic co-educational schools.”
