A network of experts in reproductive and children’s environmental health

Welcome to the PEHSU National Classroom!

The Pediatric Environmental Health Specialty Units are dedicated to increasing knowledge about environmental medicine among healthcare professionals regarding children’s environmental health. Many of the environmental risks that lead to ill health can be lessened or prevented with proper healthcare provider education and preparation. Healthcare providers are well-positioned to deliver care and health education needed to protect children from environmental threats and to share information with colleagues.

We offer various educational opportunities that include the ability to obtain continuing education (CE). See below for a description of the opportunities we offer or select an option using the right navigation for more information.


All courses and on-demand webinars are hosted on the PEHSU program's learning site: www.pehsuclassroom.net. Registration is easy and allows you to access courses on your PC or mobile devices, search our complete course catalog, enroll in courses, track your progress, and print completion certificates. Upon completion, participants are provided instructions for obtaining CE.
