In the Early Childhood and Lower School divisions, the homeroom teachers form the cornerstone of the advising/counseling/guidance component of the students' lives. They listen to the hopes, dreams, fears, concerns, and issues of the students, their parents and their teachers and they try to offer appropriate guidance, counsel and advice. Division coordinators, Assistant Head and the Head of School may also be a part of these conversations and of course, the school psychologist and school nurse offer invaluable resources regarding the needs of any student.

In the Middle School there is a formal Advisory Program. The advisor is the first line of communication for parents, students, teachers and administrators when there is a concern/issue/commendation/inquiry that is not specific to a subject area. Advisors counsel, guide and advise students with input gathered from division coordinators, the Assistant Head, Head of School, parents, teachers and/or the school psychologist. Bi-monthly (grades 4 through six) and weekly (grades seven and eight) lunch meetings are held with advisory groups to promote connections and to discuss topics of student or teacher concern. Once a month individual advisor-advisee meetings take place. These meetings ensure that communication lines are open.

The close-knit homeroom system is also a foundation of BCD's guidance, counseling and advising program in all divisions. Homeroom (grade level) group building exercises, field trips, lunch and snack times, and social activities are all aimed at creating an atmosphere of acceptance, tolerance and kindness and of developing skills of leadership and citizenship. These skills and understandings form an integral part of BCD's view of "guidance" of young people.

On the Winthrop Campus, the Assistant Head of the Secondary School coordinates guidance procedures. Counseling programs stem primarily from the advisory system. A team of twelve faculty advisors works with groups of five to six students, meeting on a biweekly basis. Advisors work in conjunction with the school psychologist in counseling and advising. Parents contact the student's advisor first on all academic and social matters. When appropriate, the advisor alerts the Assistant Head and/or school psychologist of parental concerns. The Assistant Head then follows up with the parents, student, and advisor until the issue is addressed and resolved. The school psychologist is available five days per week. Students and faculty may make appointments confidentially through the administrative assistant to seek counseling. Advisors meet with the school psychologist on a weekly basis to discuss students of academic or social concern.
