|The Alternative Education Resource Organization (AERO)
"AERO's goal is to advance student-driven, learner-centered approaches to education. AERO is considered by many to be the primary hub of communications and support for educational alternatives around the world. Education Alternatives include, but are not limited to, Montessori, Waldorf (Steiner) Choice, Democratic, Homeschool, Open, Charter, Free, Sudbury, Holistic, Virtual, Magnet, Early Childhood, Reggio Emilia, Indigo, Krishnamurti, Quaker, Libertarian, Independent, Progressive, Community, Cooperative, and Unschooling. One of AERO's areas of expertise is democratic process and democratic education, but equally important is the networking of all forms of educational alternatives."
