In the fall of 1985, Joan Walter, then President of The Rivers School Parents League, conceived the idea of PIN as a means for parents of Boston area Independent schools to come together to exchange information.

The groundwork for PIN was laid when a symposium was held at Rivers and a questionnaire was sent to potential member schools. In February 1986, the first meeting was held with ten schools in attendance. In June 1989, the Lower School Division was added.

In 1994, PIN became a Massachusetts not-for-profit corporation. Current PIN membership includes over 68 schools (and the number is growing!) and represents a cross-section of the independent school community: grades Pre K-12, day and boarding, single-sex and co-educational schools.

The first lecture in our lecture series was held in the fall of 1985. Subsequently, the monies raised funded our worthy community service programs at PIN member schools.  In 2005, the lecture series was named the Annual Joan Walter Lecture Series in honor of Joan Walter, founder of PIN.

The founding members of PIN were Beaver Country Day School, Belmont Hill School, Buckingham Browne & Nichols, Dana Hall School, Middlesex School, Newton Country Day School, Noble & Greenough School, Rivers School, St. Sebastian’s School, and Thayer Academy.


The Parents’ Independent School Network facilitates communication, promotes parental networking and awareness, and provides programs to our New England area member school communities.
