For the art historians among us: the National Art Education Association.
Here’s what the NAEA has to say about itself:
Founded in 1947, The National Art Education Association is the leading  professional membership organization exclusively for visual arts  educators. Members include elementary, middle and high school visual  arts educators, college and university professors, researchers and  scholars, teaching artists, administrators and supervisors, and art  museum educators, as well as more than 45,000 students who are members  of the National Art Honor Society or are university students preparing  to be art educators.
We represent members in all fifty states plus the District of  Columbia, U.S. Possessions, most Canadian Provinces, U.S. military bases  around the world, and twenty-five foreign countries.
Mission
The National Art Education Association (NAEA) advances  visual arts education to fulfill human potential and promote global  understanding.
Core Values 
NAEA staff and members work to support professional growth, change, and leadership through:
 Mentoring
  Networking and collaborating
  Participating in art education conferences
  Developing and disseminating exemplary resources on art education
  Building a professional community by contributing our time and talents to others
  Valuing our diversity and committing ourselves to equity
They have a fairly complicated grid of membership costs by state; for Massachusetts, it’s $70 for full, active membership and $30 for a student membership. For those joining us from other states, you can navigate this PDF to find out your dues. In terms of benefits, you get a fairly robust series of publications, access to a members-only section of the website that includes lesson plans and gallery activities, discounts on all sorts of things, and access to grants and other funding opportunities.
The professional development section of their website is really fantastic: access to lesson plans, all sorts of resources for the practice of art education, book and material reviews, and a mentor program. They also maintain a robust “Research” section, with reports and tools for the thoughtful analysis of art education. Like AAM, NAEA is involved in advocacy for its professional interests, and they have some good advice that goes way beyond art education and is applicable to anyone speaking for a cultural cause.
So go, check them out!
(editor’s note: we’ve made a small correction to our previous post on the AASLH; student members aren’t mailed a paper copy of History News, but they can access back issues online.)
