Continuing education designed by professionals who understand professional practice

Coursework supported by qualified technical professionals
Courses are developed and evaluated by experienced engineering educators, licensed professional engineers, and subject-matter experts. Their combined academic and professional backgrounds help maintain material that is technically useful, clearly presented, and appropriate for continuing professional development.
Online-PDH courseware is designed around recognized continuing professional competency principles. Because licensing requirements vary, each licensee should confirm that a selected course is appropriate for the subject, delivery, and documentation requirements of the applicable licensing board.
