Students are expected to volunteer with their choice of surrounding institutions, including among others, retirement manors, medical centers, museums, a historical society, and a food bank.

Chiaravalle seems to have a large community support system, which is reflected in an online community. Searching for the parameters "Chiaravalle Montessori School" brings up many videos created by both students and parents taken at school events and activities or just proclaiming devotion and support for the school. The middle school boasts long periods of uninterrupted work time, similar to traditional lower grade classes, as well as six-week focused work cycles, frequent progress reports and self-assessments, and homework of merely classwork that was not finished during the day.
Notable classes for students include a Speech and Communications course in which is taught "grace and courtesy, listening skills, note-taking, active participation in group discussions, clear articulation of ideas, and ... frequent individual and group presentations. Students learn a variety of communication skills, such as acknowledging others, using "I" messages, active listening, goal-setting, and group decision-making. ... Students are able to practice communication skills daily by working in community meetings, class committees, small group cooperative projects, and peer and multi-age teaching activities." Another notable class, as suggested by Maria Montessori, is Outdoor Education, in which students, for one week, "experience real responsibility as they budget, shop, cook, and clean for themselves and each other. They use nature as a source of inspiration for academic work, studying ponds, streams, lakes, land management, astronomy, and related topics." Other non-traditional classes Career Education/Service Learning in which students are given a choice of assisting a teacher in lower grades or taking up an internship with a local business; Spanish; a health class that involves daily reflection; and "several" field trips each year.
