The Museum and Education Principles and Standards put out by the American Museum Association (AAM) are a great guide for museum education professionals. The document outlines the principles and standards that were drafted by the Committee on Education, a section of the AAM, in 1990 and revised in 2005. The document lists the three major principles that museum educators should follow: accessibility, accountability and advocacy. The group hopes that this document will offer information to museum educators and guide them to support informal education. The document also outlines what it means to be a museum educator and offers further resources. This document is very helpful to an understanding of what it means to be a professional museum educator.
