No. “CHMM” is a trademarked designation for “Certified Hazardous Materials Manager.” Use of the designation by anyone who has not been certified by the Institute of Hazardous Materials Management (IHMM) is a violation of trademark law.
The hazardous materials programs offered by the University of California are similar to mini-degree programs, but they are strictly academic. They issue a certificate of completion, not a certification! The CHMM program combines academics and experience as prerequisites, and requires that you pass the national CHMM examination. That is the only way to become a CHMM.
