The National Project for Excellence in Environmental Education (NPEEE) conducted a series of workshops to familiarize formal and nonformal educators with the NPEEE Guidelines for environmental education. These workshops were then evaluated to determine participants’ satisfaction and how they intended to use the Guidelines to improve their EE efforts. Data collection instruments included a survey administered to all program participants at the end of the workshop, as well as a follow-up survey that was sent to a random sample of participants 4-5 months after the workshop. Based on the results of the evaluation workshop instructors received additional information and guidance on implementing and evaluating the workshops.
