The Environmental Education Materials: Guidelines for Excellence comprises a set of recommendations for developing and selecting environmental education instructional materials. 

These guidelines aim to help producers of activity guides, lesson plans, and other instructional materials create high-quality products and to provide educators with a tool to evaluate the wide array of available environmental education materials. Through the National Project for Excellence in Environmental Education, the North American Association for Environmental Education (NAAEE) is taking the lead in establishing guidelines for the development of coherent and comprehensive environmental education materials and programs. These guidelines draw on our best thinking honed by scholars and practitioners across a variety of fields and settings, including formal and nonformal education, curriculum development, instructional design, early childhood education, and adult education.

To ensure that these Guidelines for Excellence reflect a widely shared understanding of environmental education, they were developed by a team of environmental education professionals from a variety of backgrounds and organizational affiliations. This team took on the challenge of turning ideas about quality into tangible recommendations and examples. In addition, drafts of these guidelines were circulated widely to practitioners and scholars in the field (e.g., teachers, educational administrators, environmental scientists, and curriculum developers), and their comments were incorporated into successive revisions of the document. As such, hundreds of practitioners have participated in the writing of these guidelines.
