At our 2018 re-accreditation visit, the following themes for recognition were noted:

  • The school has shown a commitment to the culture and community through the practice of educating students in academics and character traits and providing support for opportunities to practice community values providing students with occasions to apply and achieve in learning, thinking, and life skills.
  • The diverse board makeup and individual commitment to the mission of the school allow the school to function under the leadership of a strong board with daily school operations managed by uniquely qualified and experienced leadership, faculty, and staff, thus creating a highly functional management team.
  • The Branch School's inspirational and caring teachers infuse a positive, safe environment conducive to augmenting student's academic, social, and emotional growth.

Their report stated that "all of the classrooms were warm and welcoming.  Respect for others is the standard and was easily observed throughout the school.  Students responded eagerly to questions and were not intimidated by the fear of failure.  Parents, students, and staff referred to the “family and community” relationship that is a hallmark of The Branch School."
