A Sudbury school is a type of school, usually for the K-12 age range, where students have complete responsibility for their own education, and the school is run by direct democracy in which students and staff are equals. Students individually decide what to do with their time, and tend to learn as a by-product of ordinary experience rather than through coursework. There is no predetermined educational syllabus, prescriptive curriculum or standardized instruction. This is a form of democratic education. Daniel Greenberg, one of the founders of the original Sudbury Model school, writes that the two things that distinguish a Sudbury Model school are that everyone - adults and children - are treated equally and that there is no authority other than that granted by the consent of the governed.
While each Sudbury Model school operates independently and determines their own policies and procedures, they share a common culture. The intended culture within a Sudbury school has been described with such words as freedom, trust, respect, responsibility and democracy.
The name 'Sudbury' originates from the Sudbury Valley School, founded in 1968 in Framingham, Massachusetts, near Sudbury, Massachusetts. Though there is no formal or regulated definition of a Sudbury Model school, there are now more than 60 schools that identify themselves with Sudbury around the world. Some, though not all, include "Sudbury" in their name. These schools operate as independent entities and are not formally associated in any way.
Sudbury schools are based on:
"The fundamental premises of the school are simple: that all people are curious by nature; that the most efficient, long-lasting, and profound learning takes place when started and pursued by the learner; that all people are creative if they are allowed to develop their unique talents; that age-mixing among students promotes growth in all members of the group; and that freedom is essential to the development of personal responsibility."
All aspects of governing a Sudbury School are determined by the weekly School Meeting, modeled after the traditional New England town meeting. School Meeting passes, amends and repeals school rules, manages the school's budget, and decides on hiring and firing of staff. Each individual present — including students and staff — has an equal vote, and most decisions are made by simple majority
