Although our visionary founder Mary Caswell opened the doors of Marlborough over a century ago, her vision for an educational community that would prepare women for lives of meaning and purpose as well as ensure the continued growth and innovation of the school—articulated today in its Mission Statement, Core Values, and Strategic Plan—has remained an inspiration for her seven successors and solidified Marlborough's place as a national leader in secondary education.

Mission Statement

Marlborough School, founded in 1889, is an independent, urban day school serving a diverse group of young women. The School is committed to delivering a superior college preparatory education in an environment imbued with high ethical values. Marlborough is dedicated to the philosophy that academic excellence, leadership skills, and confidence flourish best in an environment exclusively devoted to the education of young women. The Marlborough community enables each student to develop her fullest potential so that she may become an actively engaged global citizen.

Core Values

Marlborough School is a diverse and inclusive community of students, families, faculty, staff, alumnae, and friends. Through experiences offered within our community, the young women at Marlborough learn to face the world with courage, compassion, flexibility, and commitment.

Marlborough School serves as a model of educational excellence and strives to inspire and support each student to achieve her “personal best.”

Marlborough School offers an environment in which students are encouraged to discover their potential, increase their competence, develop leadership skills, and expand their self-reliance.

Marlborough School’s culture is infused with honor, trust, individual responsibility, and mutual respect. The School’s long-standing Honor Code, inspired and created by Marlborough students, serves as a daily reminder of the importance of honesty and integrity in the community.

Strategic Plan

As Marlborough neared successful completion of its 2000-2010 Strategic Plan, the School’s Board of Trustees embarked on the process of envisioning our future for the next decade. Students, parents, alumnae, and employees were surveyed to assess and identify the School’s current strengths, as well as areas of improvement for the future. The Trustees led an 18-month-long planning process that included examining the survey results, revisiting the School’s mission, analyzing data comparing Marlborough to other independent schools, and meeting with college admissions officers, educators, researchers, and other consultants. This process led to our new Strategic Plan, “The Next Ten Years at Marlborough 2010-2020.” Executing the Plan will keep Marlborough not merely at the forefront of educating young women, but at the forefront of independent school education in the nation.

Over the next ten years, we look to assertively pursue the following goals:

  • Preparing Marlborough Girls for the Future
  • Growing, Developing, and Sustaining Marlborough
  • Leading Marlborough Today, Leading Marlborough Tomorrow
  • Engaging Locally, Leading Globally

The Understanding

Marlborough School is a community built on honor, trust, individual responsibility, and mutual respect. The School feels strongly that self-discipline is more valuable than imposed discipline and expects good conduct and behavior from every member of the School community. It is the responsibility of all members of the community to follow established rules so that the School functions safely and individual needs can be met and respected. A student represents Marlborough School when she is on or off campus. Therefore a Marlborough student must take responsibility and will be held accountable for her actions at School, at a School-related function (on or off campus), in the neighborhood or vicinity of the School, while wearing Marlborough apparel, and in other circumstances where the student's conduct may reflect back upon the School, its students, faculty, staff, or community.

Honor Code and Pledge

Marlborough School supports an Honor Code. We believe that to be honorable we must demonstrate honor and pride within ourselves and trust throughout our School community. Each student must respect herself as well as the rights and property of others. The Honor Principle means that we not only abide by these values, but that we support and encourage others to uphold them. A common understanding of these expectations must exist among employees and students.

Our School believes in the utmost importance of honesty and integrity. Students and all other members of the Marlborough community must believe in these values and follow the standards that define them.

Parents and students affirm their support of all School rules, including the Honor Principle, in the Student Handbook of Expectations when they sign The Understanding each fall. The Honor Ceremony, held at the beginning of the School year, explains the Honor Code to new students and heightens awareness for returning students.
