"Developmentally appropriate practice is the foundation for all of NAEYC's work—publications and conferences, professional development/training, policy/advocacy, and accreditation of both college-level preparation and child care programs." This CD-Rom was designed to acompany a printed book to be distributed to educators. The CD includes videos illustrating examples of educators in actions as well as commentary from the development team. PDF handouts were also included as educational training material. It was developed as an application for use on Mac and PC.
